TOP10chemicallycompetentcells
OverviewThis protocol is a variant of the Hanahan protocol [1] using CCMB80 buffer for DH10B, TOP10 and MachI strains. It builds on Example 2 of the Bloom05 patent as well. This protocol has been tested on TOP10, MachI and BL21(DE3) cells. See Bacterial Transformation for a more general discussion of other techniques. The Jesse ''464 patent describes using this buffer for DH5α cells. The Bloom04 patent descri......阅读全文
