You might consider trying a few ul of your library as a template - no
preparation required. I routinely (and often successfully) use gt11
libraries as a template for PCR to amplify fragments up to ~ 1 kb. I
recommend starting with 5% of your PCR reaction volume. I don't deviate
from a standard hot-start of 94C for 30 sec prior to the first cycle.
Another sometimes effective way to combine PCR and lambda libraries is to
design primers flanking the cloning site and to use them individually with
complementary specific primers. This will occasionally result in the
amplification of a large chunk of your gene of interest without resorting to
Of course the better the library, and probably the better represented your
sequence is, the better these things work.
