Archaeal Genome Browser Database, Marmoset Genome Browser and Blat Server, Clean Genome E. coli

The Archaeal Genome Browser Database, a visualization tool and an integrated repository for archaeal functional genomics data, is available here. It was developed by the Todd Lowe Lab in the University of California Santa Cruz biomolecular engineering department, in collaboration with the UCSC Genome Browser team.

A genome browser and Blat server for the Callithrix jacchus marmoset genome is available here. The June 2007 assembly, WUSTL version Callithrix jacchus-2.0.2, UCSC version calJac1, was produced by Washington University School of Medicine’s Genome Sequencing Center.

Scarab Genomics has launched the Clean Genome E. coli strain and competent cells. According to the company, the strain’s genome is very stable because of the removal of all mobile insertion sequence elements. The absence of mobile elements eliminates the danger of undesirable IS transposition into a customer’s clone and reduces the mutation rate of the strain. The competent cells increase success in cloning difficult or “unclonable” genes by eliminating cloning artifacts due to IS transposition and minimizing plasmid rearrangement, according to Scarab.
