   Dear neters,

I am using a Lambda ZAP II cDNA library and I would like to screen for a
protein using plaque lift. However my detection system is not very good
and I need about 5 micrograms of recombinant protein to be able to detect

Has anybody an idea of how much recombinant protein is produced in a
plaque when inducing with IPTG after one night ? Maybe I could produce
'large' plaques (2 mm diameter) to have enough protein?

Thank you in advance

Sincerely yours
