Abstract

Collections of nonredundant, full-length complementary DNA (cDNA) clones for each of the model organisms and humans will be important resources for studies of gene structure and function. We describe a general strategy for producing such collections and its implementation, which so far has generated a set of cDNAs corresponding to over 40% of the genes in the fruit fly Drosophila melanogaster .

2. Total RNA was prepared by hot phenol extraction. mRNA was purified with the Stratagene Poly(A) Quik mRNA isolation kit. mRNA quality was assessed by RNA blots with Delta and Notch clones as probes. First strand cDNA synthesis was carried out with the Stratagene λZAPII-cDNA synthesis kit with the substitution of SuperscriptII reverse transcriptase from GIBCO-BRL. The cDNAs were directionally cloned into the λZAPII and pOT2a vectors. Phage and plasmid libraries were amplified once. The plasmid libraries were size fractionated with GIBCO-BRL S-500 cDNA size fractionation columns and clones with inserts larger than 1 kb were pooled and transformed.
