title: Preparation of a differentially expressed, full-length cDNA expression library by RecA-mediated triple-strand formation with subtractively enriched cDNA fragments.
abstract: We have developed a fast and general method to obtain an enriched, full-length cDNA expression library with subtractively enriched cDNA fragments. The procedure relies on RecA-mediated triple-helix formation of single-stranded cDNA fragments with a double-stranded cDNA plasmid library. The complexes were then captured from the solutions using the digoxigenin-antidigoxigenin paramagnetic beads followed by recovery of the enriched double-stranded cDNA expression library. We have observed a linear relation between the capture of full-length cDNAs in the library and the fold enrichment in the subtracted cDNA population.
