WebDH5-Alpha Cell. DH5-Alpha Cells are E. coli cells engineered by American biologist Douglas Hanahan to maximize transformation efficiency. They are defined by three [1] mutations: recA1, endA1 which help plasmid insertion and lacZΔM15 which enables blue white screening. The cells are competent and often used with calcium chloride … Web54 rows · One Shot ® TOP10 Chemically Competent E. coli: ThermoFisher (Invitrogen) C4040-03: 20 x 0.05ml: NEB 10-beta Competent E. coli (High Efficiency) C3019: 20 x …

WebApr 15, 2008 · DH10B got some more mutations in restriction systems (mcr-system, if memory serves) that can regognize methylated foreign DNA and degrades it. Thus in DH10B you can also insert DNA that was methylated (as you stated). However, there is also DH5alpha MCR, that carries the same mutation, so it can also be used for methylated DNA. WebWe use XL-10 Gold E. coli, but have successfully tested DH5a, TOP10, and Mach1. No common lab cloning strain has failed so far. What is most important is the transformation efficiency of the strain: when asking the cell to perform multiple recombination events, all linear fragments need to get into the same cell.
