Description
For use in pBLU® transformation experiments. This is a mutant E. coli strain incapable of producing ,223;-galactosidase, which is necessary for the breakdown of lactose or X-gal, a lactose analog. When these bacteria are transformed with pBLU®, they will break down X-gal (and lactose) and this results in blue colonies and slant culture.
Note: Culture should be used within 1 month but is best used within 2 weeks of delivery. Store at +4° C.
