pGEM Beta-Gal Control DNA
pGEM beta-Gal Control DNA contains the coding sequence of beta-galactosidase downstream of an E. coli wildtype lacZ promoter. pGEM beta-Gal Control DNA can be used as a positive control in the E. coli S30 Extract System for Circular DNA. The wildtype lacZ promoter is not efficient for initiating transcription from a linear DNA template. Supplied as a 0.5mg/ml solution in TE buffer.
