We want to make a fish genomic library in Lambda GEM 12 vector (Promega).
The Lambda GEM 12 arms have been cut with BamHI restriction enzyme and we
have eliminated the central stuffer (14 Kb) by electrophoresis in low
melting agarose gel. The genomic DNA has been cut with Sau3aI restriction
enzyme and dephosphorilated. Part of this genomic DNA has been
selectioned by electrophoresis low melting agarose gel about 10 - 20 Kb
size. We have tried all kind of combinations between Lambda GEM 12 BamHI
arms and our genomic Sau3aI DNA in the ligation reaction. We have also
tried several host strains like LE392, NM538 and KW251. What could we
check to increased our very low number of recombinants?. Many Thanks.
