product description

GoldBio’s GB10B™ Chemically Competent E. coli cells are equivalent to DH10B cells. GB10B™ cells are high efficiency and suitable for a wide variety of applications such as cloning and sub-cloning. GB10B™ Chemically Competent E. coli cells have multiple features including the ɸ80lacZ∆M15 marker, which provides α-complementation of the β-galactosidase gene with blue/white screening protocol. These cells also have the mcrA genotypic marker and the mcrBC, mrr deletion, which allows for cloning of DNA that contains methylcytosine and methyladenine.

Product Specifications Competent cell type: Chemically competent Equivalent to: DH10B Species: E. coli Transformation efficiency: ≥8.2 x 106 cfu/µg pUC19 DNA Blue/white screening: Yes
