Detergent and Competent Cells...

Fri Aug 27 04:22:48 EST 1993

	Just a quick question, has anyone out there ever had troubles with
detergents used in washing glassware which is then used for making
competent bugs (eg NM522/MC1061's etc.) We changed our detergent a few 
months back, and coincidently our ability to make high competency
bugs seemed to fall. 10^4 colonies /microgram seemed to be the best
I could get, whereas this was at least 10^6, 10^7 before. Before we blame 
the detergent I thought I'd see if this has happened to others first.

	Any replies would be much appreciated, either to this newsgroup
or to me via email.
