I am having trouble in getting regular amounts of pET (19b or 11a, with ot
without insert)) in DH5alpha.
I have only 30-50ug of plasmid from a 200ml LB culture (Cesium Chloride prep).
The DH5alpha strain is ok since I get 500-700ug of pUC in the same conditions.
Does anyone on the net have an answer to that problem ?
I am planning to do cloning with these pETs and I bet I won't be able to
check the clonings with that low yield.
