|Highly reactive rabbit antiserum directed against the E. coli strain W3110. The antibody is a perfect tool to determine bacterial contamination in your W3110 expression experiments.
Info Box: W3110
E. coli W3110 (DSM 5911, ATCC 27325) is still the workhorse for many recombinantly expressed proteins for pharmaceutical purposes.
The strain has a well documented pedigree and is one of the most unmodified K12 strains. It was derived from a K12 wild-type by UV-irradiation and two spontaneous mutations. It is F- and lambda-. On the other hand it is easily detected by a large genomic inversion. The strain is often modified for the specific demands of the expression system.
