Promega recommend a final concentration of ampicillin in 
LB/ampicillin/IPTG/X-gal plates (for E. coli JM 109 transformed with 
T-vector) of 100 ug/ml...   Can I get away with only 50 ug/ml as 
suggested by a lab manual or is this a false economy?

Anyone got a sure fire cheap plate recipe?

Thanks!!

B.
