Library amplification problems - Glenn Samwell

Hi yeast users,

I am trying to amplify a human brain library (Clontech) that has been 
cloned into pACT2 and transformed into E. coli strain BNN132. The yields 
I have been getting are very poor and I think that it is because the 
bacterial cells are not lysing properly. I am using standard maxi-prep 
protocols and I'm not sure what else to try. I thought maybe a couple of 
freeze-thaw cycles may assist in cell lysis. Has any body had the same 
problems, and what, if any, methods did you use to get better yields?

Thanking you in advance,


Glenn
