Dh10-Beta Competent E. Coli
The DH10B competent E. coli has a transformation efficiency of 1 x 109 cfu/µg for supercoiled DNA and is ideal for high-efficiency cloning and plasmid propagation. It allows stable replication of high-copy number plasmids. Comparing with DH5a, it could be efficiently transformed of methylated DNA from genomic preparation there for it is more useful for generating genomic libraries containing methylated cytosine or adenine residues.
