Dh10-Beta Competent <i>E. coli</i>
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. In comparison with DH5a, methylated DNA from genomic preparation could be efficiently transformed into DH10B, therefor, the DH10B cells are more applicable than DH5a in generating genomic libraries containing methylated cytosine or adenine residues.
