I am attempting to electroporate a 'rescued' lambda ZAP II cDNA library (ie.
is in pBluescript)
into E. coli cells (more specifically, XL-1 Blue cells). The problem is that
I get very few colonies
from this (my positive control works well and my cells are competent). I'm
presuming the
problem is that most of the DNA is quite large. Is this the most likely
reason? Is there a better

Thanks in advance,
