I have often blogged about my trials and tribulations with the NCBI database.This morning I was trying to locate all the kappa light chain genes from the NCBI database.
I tried the following search
The results I got were a curious mix of microbe genomes ranging from Aspergillus Niger to Salmonella enterica. Maybe I left my search skills at home or my eyes are playing tricks on me.
Addendum: Eric Jane from Uniprot showed me how to do the same query on Uniprot beta. Uniprot really rocks. Not only could I do the query , but also downloaded the results in batch mode as fasta sequences and in the xml format.Thanks eric , I would definitely recommend uniprot beta to everyone. Isabelle phan from uniprot did post an excellent screencast detailing the features of uniprot beta at this link on Bioscreencast.com . Do check it out as well as Erics comments below.
