WebThe chemically competent Stellar Competent Cells are treated with calcium chloride to assist attachment of the plasmid DNA to the competent cell membrane, while the Stellar Electrocompetent Cells are prepared for transformation via electroporation. Both formats use an E. coli HST08 strain that provides high transformation efficiency and have ... WebRestriction sites that are blocked by Dam or Dcm methylation can be un-methylated by cloning your DNA into a dam–, dcm– strain of E. coli, such as dam–/dcm– Competent E. coli ( NEB #C2925 ). Restriction sites can also be blocked if an overlapping site is present. In this case, part of the Dam or Dcm sequence is generated by the ...

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 …
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. WebMe too but I think that TOP10 that we have grow considerably slower than the DH5alpha I remember. DK. Nick Theodorakis 2006-02-25 01:23:57 UTC. Permalink.
