Intended use

The INNO-LiPA MYCOBACTERIA v2 assay is a DNA probe test, for in vitro use, designed for the detection and identification of the genus Mycobacterium and 16 different mycobacterial species from liquid and solid culture, based on nucleotide differences in the 16S-23S ribosomal RNA (rRNA) spacer region.

Test Principle

INNO-LiPA MYCOBACTERIA v2 is based on the reverse hybridization principle. Biotinylated DNA material is hybridized with specific oligonucleotide probes immobilized as parallel lines on membrane-based strips. After hybridization, streptavidin labelled with alkaline phosphatase is added and bound to any biotinylated hybrid previously formed. Incubation with 5-bromo-4-chloro-3-indolyl phosphate and nitroblue tetrazolium (BCIP/NBT) chromogen results in a purple/brown precipitate.

To perform the INNO-LiPA MYCOBACTERIA v2 assay, amplification of the 16S-23S ribosomal rRNA spacer region should be carried out (see INNO-LiPA MYCOBACTERIA v2 Amp instructions for use). Amplification products are subsequently hybridized using 1 typing strip onto which 22 parallel DNA probes lines and 2 control lines are fixed (Figure 1).

INNO-LiPA MYCOBACTERIA v2: Steps involved Step 1 Amplification of 16S-23S rRNA spacer region of Mycobacterium species

(INNO-LiPA MYCOBACTERIA v2 Amp). Step 2 Hybridization and stringent wash of the amplified 16S-23S rRNA spacer

region with specific probes immobilized on a strip. Step 3 Color development. Step 4 Interpretation of the signal pattern.

Specimens

This test utilizes biotinylated amplified DNA material. An amplification kit, utilizing biotinylated oligonucleotide primers, is available as an accompanying tool for amplification of 16S-23S rRNA spacer region of Mycobacterium species (INNO-LiPA MYCOBACTERIA v2 Amp) from the specimen: fully grown cultured samples (liquid or solid culture) from e.g. sputum. This amplified material is used on INNO-LiPA MYCOBACTERIA v2 to detect the Mycobacterium genus and the following Mycobacterium species: M. tuberculosis complex, M. kansasii, M. xenopi, M. gordonae, M. genavense, M. simiae, M. marinum and M. ulcerans, M. celatum, MAIS, M. avium, M. intracellulare, M. scrofulaceum, M. haemophilum, M. chelonae complex, M. fortuitum complex and M. smegmatis.

Remarks and precautions

- Do not mix reagents with different lot numbers. - Avoid microbial contamination of reagents. - Use tweezers to handle strips. Do not touch strips with your hands as the oils from

your hands could interfere with hybridization and color development. - Use only pencil to write on the strips. The assay reagents may remove ink from the

strips.

Page 7: INNO-LiPA MYCOBACTERIA v2

80346 INNO-LiPA MYCOBACTERIA v2 / 28723 v2 / KEY CODE: FRI92473 p 7/16

- Make sure that the test strips are placed in the troughs with the side bearing the coated membrane facing upwards (this side is marked).

- The strips are designed to be used only once! - All vessels used to prepare conjugate and substrate working solutions should be

cleaned thoroughly and rinsed with distilled water. - Use a new sterile pipette tip (cotton-plugged) for each specimen. - To prevent PCR contamination, maximize the physical separation of the pre- and

post-amplification steps. Do not return samples, equipment, or reagents to the area where you performed the previous step. If you need to return to a previous work area, first perform the appropriate anti-contamination safeguards.

- Do not reuse the troughs.

Test procedure

Please read Remarks and precautions before performing the test. NOTE: - Throughout the different incubation steps, the test strips should always remain in the

same trough. - Before incubation, check the temperature of the water bath using a calibrated

thermometer, and adjust the temperature if necessary before placing the tray in the water bath. Always close the lid.

Procedural notes

- The hybridization and stringent wash incubation at exactly 62°C ± 0.5°C are the most critical steps to avoid false-positive (temperature too low) or false-negative/very weak signals (temperature too high). A shaking water bath (80 rpm) with a closed lid allows good control of temperature variations. Strict temperature control with a calibrated thermometer is necessary.

- The shaking of the solutions over the strips is critical in achieving maximum sensitivity and homogeneous staining. During shaking, the strip surface should be completely submerged. Do not use a hot air shaker.

- The amplitude of the motion generated by both the shaking water bath (hybridization procedure) and the orbital, reciprocal shaker or rocking platform (color development procedure) is critical in achieving maximum sensitivity and homogeneous staining. The amplitude should be as high as possible. However, spilling of liquid over the edges of the troughs must be avoided!

- For hybridization and stringent wash, the troughs should be placed on the shaking platform of the water bath. Adjust the water level to between 1/3 and 1/2 of the height of the trough. Make sure that the troughs do not float on the water. The water should be in direct contact with the troughs.

- Shaking during incubation of the strips should be performed in such a way that both the liquid and the test strips move back and forth in the trough, without liquid being spilled over the edge of the troughs.

- Always close the lid of the water bath during incubation. - Do not cover the tray. - The liquid is aspirated from the trough with a pipette, preferably attached to a

vacuum aspirator. The tray is held at an angle to allow all liquid to flow to one end of the trough. Add 2 mL of the appropriate solution to each trough and follow the

Page 8: INNO-LiPA MYCOBACTERIA v2

80346 INNO-LiPA MYCOBACTERIA v2 / 28723 v2 / KEY CODE: FRI92473 p 8/16

protocol. Repeat this step as many times as are indicated in the test procedure (a dispensing Multipette (Eppendorf) is useful for this purpose). NOTE: Do not allow the strips to dry between the washing steps. Make sure the surfaces of the strips are not damaged when aspirating. Preferably

aspirate the liquid at the top of the strip above the marker line. Make sure the whole strip is thoroughly washed by complete submersion in the

solution. Alter the speed of the shaker when necessary.

Samples

1. Mycobacterial 16S-23S rRNA spacer amplified product (use 10 µL). 2. Blank amplified control sample (negative control) (use 10 µL).

Hybridization

1. Heat a shaking water bath to 62°C ± 0.5°C. Check the temperature using a calibrated thermometer, and adjust the temperature if necessary. Prewarm the hybridization solution and stringent wash solution to at least 37°C and do not exceed 62°C. Mix before use. All crystals should be dissolved.

2. Using forceps, remove the required number of INNO-LiPA MYCOBACTERIA v2 strips from the tube (1 strip per sample) and pencil an identification number above the blue marker line on the strip. Always include a strip for the negative control sample (no DNA added).

3. Take the required number of test troughs (1 trough per strip) and place them in the tray.

4. Pipette 10 µL denaturation solution into the upper corner of each trough. NOTE: Close the vial immediately after use.

5. Add either 10 µL amplified biotinylated product or 10 µL negative control sample to the denaturation solution and carefully mix by pipetting up and down. Always use cotton-plugged sterile pipette tips. Allow denaturation to proceed for 5 minutes at room temperature (20 - 25°C).

6. Shake the prewarmed hybridization solution and gently add 2 mL to the denatured amplified product in each trough. Take care not to contaminate neighboring troughs during pipetting.

7. Immediately place the strip into the trough with the marked side (blue Marker Line) of the membrane facing upwards. The strips should be completely submerged in the solution. NOTE: Wear disposable gloves and use forceps.

8. Place the tray in the 62°C ± 0.5°C shaking water bath (approximately 80 rpm; see “Procedural notes”), close the lid, and incubate for 30 ± 3 minutes.

Stringent wash

1. After hybridization, remove the tray from the water bath. 2. Hold the tray at a low angle and aspirate the liquid from the trough with a pipette,

preferably attached to a vacuum aspirator. Add 2 mL pre-warmed stringent wash solution into each trough and rinse by rocking the tray for 60 ± 30 seconds at room temperature. Aspirate the solution from each trough.

3. Repeat this washing step once see also Procedural notes.

Page 9: INNO-LiPA MYCOBACTERIA v2

80346 INNO-LiPA MYCOBACTERIA v2 / 28723 v2 / KEY CODE: FRI92473 p 9/16

4. Finally, aspirate the solution and incubate each strip in 2 mL pre-warmed stringent wash solution in the shaking water bath at 62°C ± 0.5°C for 10 ± 2 minutes. Close the lid of the water bath. Before incubation, check the temperature of the water bath using a calibrated thermometer, and adjust the temperature if necessary. Always close the lid. NOTE: Prepare rinse working solution and conjugate working solution during

stringent wash incubation.

Color development

All subsequent incubations are carried out at 20 - 25°C on a shaker. During the incubations, the liquid and test strips should move back and forth in the trough for homogeneous staining.

1. Wash each strip twice for 60 - 90 seconds using 2 mL rinse working solution (see “Procedural notes”). Aspirate.

2. Add 2 mL of conjugate working solution to each trough and incubate for 30 ± 3 minutes while shaking. Aspirate. NOTE: Prepare substrate working solution about 10 minutes prior to the end of the

conjugate incubation. 3. Wash each strip twice for 60 - 90 seconds using 2 mL rinse working solution and

wash once more using 2 mL substrate buffer. Aspirate. 4. Add 2 mL of substrate working solution to each trough and incubate for

30 ± 3 minutes while shaking. Aspirate. 5. Stop the color development by washing the strips twice in 2 mL distilled water while

shaking for at least 3 minutes. 6. Using forceps, remove the strips from the troughs and place them on absorbent

paper. Let the strips dry completely before reading the results. Store the developed and dried strips in the dark.

Quality control

- The uppermost blue line is the marker line. This line controls for the positioning of the plastic reading card.

- The first positive line is the conjugate control line. This line controls for the addition of reactive conjugate and substrate working solution during the detection procedure. It should always be positive and should have approximately the same intensity on each strip in the same test run.

- The second line is the Mycobacterium genus probe line (MYC genus on the reading card and data reporting sheet) which detects the presence of Mycobacterium in the test sample, and indicates whether or not an appropriate amount of amplified material was added for hybridization as the intensity of other positive lines must be compared with the intensity of this line.

- The negative control should be blank except for the conjugate control line. This demonstrates that no contamination has occurred.

Interpretation of the results

The presence of a clearly visible line is considered a positive reaction. Identify all line numbers which are positive on the INNO-LiPA MYCOBACTERIA v2 strip and determine the Mycobacterium species by using the INNO-LiPA MYCOBACTERIA v2 interpretation chart.

Limitations of the procedure

- Use of this product should be limited to personnel well trained in the techniques of amplification and hybridization.

- Good laboratory practice as well as careful performance of the procedures specified will allow specific amplification.

- Polymerase inhibition might be the reason for complete failure of the assay! - Powder from disposable gloves and sodium hypochlorite has an inhibiting effect on

amplification. - A polymorphism in the target region, although rare, may result in a false positive or

negative reaction of one of the probe lines.

Test performance

The INNO-LiPA MYCOBACTERIA v2 was evaluated at one Belgian center (Antwerp) and internally on a selected sample population, representing predominantly those species for which probes were added or improved on the INNO-LiPA MYCOBACTERIA v2.

A total of 73 mycobacterium specimens, 21 non-mycobacterium species and 25 media were tested at the center. All 73 Mycobacterium strains reacted with the Mycobacterium genus (MYC) probe. Sixty-six of these isolates gave concordant results with the reference method after initial testing, while after discrepancy testing 71 of the 73 isolates were concordant. The 2 remaining discordant samples were M. intracellulare 2 isolates that were correctly classified as members of the MAIS complex.

All 11 mycobacterial species tested in-house reacted with the Mycobacterium genus (MYC) probe and 10 of these strains gave an interpretable LiPA result concordant with the reference method.

Overall, diagnostic sensitivity was 98.8%. Accuracy after initial testing was 91.6% and after discrepancy testing, 97.6%. Amplification was obtained for 20 of the 21 non-mycobacterial species and none of the amplified material reacted with the Mycobacterium genus (MYC) probe (100% specificity). The 25 medium samples were negative on strip except for the conjugate control line.
