I cannot find the IgG protein from Lama pacasIgG protein from Lama pacas in your server.

“Lama pacas” = Lama guanicoe pacos (Alpaca) (Lama pacos)40 entries in UniProtKB (5 Swiss-Prot, 35 TrEMBL), but no IgG;98 entries at the EMBL database, no IgG;

In addition:Ig are not annotated in UniProtKB/Swiss-Prot (currently many Ig sequences are stored only in UniParc);Lama pacos is not an annotation priority.

Dear Folks, Dear Folks, I cannot find an entry for I cannot find an entry for human human apolipoprotein B100apolipoprotein B100 in Swiss-Prot/TrEMBL. in Swiss-Prot/TrEMBL.Am I doing something wrong? Am I doing something wrong?

In the annotation process, we try to add all synonyms found for a

given protein/gene in the literature and other databases.

In the future, our search engines will cope with dashes, Roman/Arabic

figures, etc.

I am trying to locate the entry ofr the human beta-beta-2 adrenoreceptor2 adrenoreceptor protein, but I don't seem to get any entries. Can you help me to locate this entry, please?

The missing synonym was added

I found that the UNIPROT entry for human MAPKAKK3 is still a TREMBL entry (since MAPKAKK3 is still a TREMBL entry (since 1996)1996) and could not be found in SWISSPROT. Is there a specific reason why certain entries do not enter the SWISSPROT section and get

an'correct UNIPROT ID' ?

I wish to retrieve separately, all the bacteria I wish to retrieve separately, all the bacteria and viruses protein sequences with and viruses protein sequences with virulence factorsvirulence factors, but what I manage to get when i type "virulence" as a keyword are all the protein sequences with virulence as a keyword. Are the sequences i got here only from bacterial and virus? Any other organisms have this virulence factors? How could I specified the sequences,based on viral and bacterial virulense factors? I ll be really appreciated if you could help me. Thank you.

Dear Sirs,We need deacetylase for the following purposes:1. Deacetylation of fiber obtained from chitin.2. Chitin deacetylation for obtaining chitosan oligosaccahrides.Evidently, it will be different types of deacetylase, because in case of the fiber decrease of molecular weight is not allowed, while in case of chitin deacetylation it is allowable and even desirable for oligomerisation of the product during deacetylation.We ask you to send us the example Deacetylase We ask you to send us the example Deacetylase for chitin and its price.for chitin and its price.

Dear,At this moment I am looking for : bovine TGF beta1I saw in web that you have this product with part# P18341

Could you inform me the price and delivery time ?Could you inform me the price and delivery time ?
