For every success there’s a successor. It’s called

progress. So while we knew we had something

special in Amersham™ ECL Plus, our Western

blotting team was quietly working on the next

generation of detection reagent. The result: a new

substrate that operates with superior levels of

sensitivity, signal intensity and stability than even

its famous predecessor, making it an excellent

choice for CCD imagers.Welcome to ECL Prime.

UNDERSTANDING CHANGE

New tools to advance epigenetics researchFor over 35 years, New England Biolabs has been committed to understanding the mechanisms of restriction and

methylation of DNA. This expertise in enzymology has recently led to the development of a suite of validated

products for epigenetics research. These unique solutions to study DNA methylation are designed to address some

of the challenges of the current methods. EpiMark™ validated reagents simplify epigenetics research and expand the

potential for biomarker discovery.

EpiMark™ validated products include:

• Newly discovered methylation-dependent restriction enzymes

• A novel kit for 5-hmC and 5-mC analysis and quantitation

• Methyltransferases

• Histones

• Genomic DNAs

To learn how these products can help you to better

understand epigenetic changes, visit neb.com/epigenetics.

Simplify DNA methylation analysis with MspJI

MspJI recognizes methylated and hydroxymethylated DNA and cleaves

out 32 bp fragments for sequencing analysis. Overnight digestion of

1 µg of genomic DNA from various sources with or without MspJI is

shown. Note: Yeast DNA does not contain methylated DNA, therefore

no 32-mer is detected.

TRANSFECTION REAGENTS Effective and nontoxic DNA and small interfering RNA (siRNA) de-

livery is essential for reliable scientifi c results. jetPRIME is a new

versatile and powerful DNA and siRNA transfection reagent for day-

to-day experiments. jetPRIME ensures high DNA transfection effi -

ciency and excellent gene silencing in a variety of adherent cells.

jetPRIME is ideal for DNA/siRNA cotransfection and is very gentle to

cells since it requires low amounts of nucleic acid and reagent during

transfection. The jetPRIME protocol is easy-to-follow and compatible

with the use of serum and antibiotics during transfection.

siRNA SILENCING KITEnabling researchers to perform effi cient small interfering RNA (siR-

NA) silencing (gene knockdown) experiments in small animal mod-

els, Invivofectamine 2.0 Reagent and Ambion In Vivo siRNA provide

strong and sustained knockdown of in vivo protein expression in

an easy-to-use kit. These tools accelerate the use of RNA interfer-

ence to effi ciently study gene function in animal models. Targeted

gene silencing has been demonstrated to last for more than three

weeks with a single application of Invivofectamine 2.0 Reagent

and the positive control Ambion In Vivo siRNA. The new reagents

provide a powerful alternative to the conventional use of knockout

mouse models, which can take nearly 10 months to develop. Sold

as part of a 1 ml starter kit or a 5 ml kit, Invivofectamine 2.0 Reagent

and Ambion In Vivo siRNA are synthetic, contain no components

of viral origin, and show minimal to no toxicity after extensive

initial studies.

IN VIVO TRANSFECTION KITThe PEG-Liposome siRNA In Vivo Transfection Kit is designed for

in vivo transfection of negatively charged molecules—RNA, DNA,

and small proteins. Transfection is one of the major laboratory

methods used to introduce DNA and RNA molecules into cells and

tissues. This technique makes it possible to cross cellular barriers

and deliver a gene or a small interfering RNA (siRNA) into cells for

research or therapeutic purposes. The novel PEGylated liposome-

based siRNA delivery kit is optimized for directed RNA interference

induction by effi cient delivery of functional small RNA molecules

(siRNA, shRNA, miRNA) into tissues. The liposome component

provides in vivo siRNA protection due to effi cient siRNA-liposome

encapsulation. A remarkable feature of this reagent is reduced

innate immune response and low cytotoxicity due to biodegradable

PEG modifi cation.

RNA ISOLATION When working with stored materials, researchers often need to

isolate RNA from samples that have been stored as formalin-fi xed

paraffi n-embedded (FFPE) tissue blocks. Although the tissue struc-

ture of FFPE samples will have been maintained for histological anal-

ysis, damage to the nucleic acid may have occurred through the fi xa-

tion, embedding, and storage processes impeding measurements

of gene expression levels. ExpressArt FFPE RNAready overcomes

the limitations associated with RNA degradation and interference

from RNA cross-linking in FFPE tissues. The FFPE RNAready kit ef-

fi ciently isolates and preserves mRNA using a specially developed

lysis solution and an innovative universal inhibitor of RNases that dis-

places tightly bound RNA from high-molecular-weight aggregates.

Subsequent treatment with a unique de-modifi cation reagent re-

verses formalin induced cross-links, resulting in total RNA optimized

for reverse transcription reactions and subsequent downstream ap-

plications. FFPE RNAready together with ExpressArt RNA amplifi -

cation TRinucleotide primer technology is now available to amplify

microgram quantities of high quality RNA from very small amounts

of degraded total RNA, with minimal loss of sequence.

siRNA PREMIXES

With FlexiTube siRNA Premix, small interfering RNA (siRNA) for your gene of interest and

highly effi cient transfection reagent are already premixed and provided in a single tube. Flexi-

Tube siRNA Premix includes a specialized buffer that increases the stability of siRNA-reagent

complexes. The ratio of reagent to siRNA in FlexiTube siRNA Premix is preoptimized to provide

the highest transfection effi ciency and gene knockdown. FlexiTube siRNA Premix is ready-to-

use for cell transfection. Simply add to cells and incubate. With FlexiTube siRNA Premix, RNA

interference experiments get off to a faster start, as there is no need to optimize siRNA-to-

reagent ratio. Tedious optimization experiments involving multiple transfections are minimized

or eliminated. Multiple transfections can be performed from a single FlexiTube siRNA Premix,

reducing variability, and enabling consistency across experiments and more reliable results.
