about transformation of DNA into E.Coli

Wed Aug 7 17:42:06 EST 1996

Somebody mentioned something about transformation of bacteria (with 
plasmids) without having to resort to shocking the cells at 37-42 C, and 
simply by leaving the cells on ice for 3 min. I have not come across any 
such method so far. Has anybody tried this? Is it an established method? 
How does it work? Does it mean that the 15-20 min on ice followed by HS 
can simply be cut down to just 3 min on ice? I would like some reference to 
this protocol.
