title: A randomized lentivirus shRNA library construction.
abstract: Vector based shRNA (short hairpin RNA) expression library has been widely used to screen functional genes. For two main methods that have been used to generate short hairpin RNA libraries, chemical synthesis is too expensive to be widely used and the low efficiency of enzymatic approach makes it difficult to construct. We have developed a protocol to construct a new kind of shRNA library called randomized shRNA library. Within three steps chemically synthesized randomized 19-mers DNA were efficiently converted to double-stranded DNA fragments containing shRNA templates. This kind of shRNA library permits simple and economic construction, providing another choice for whole-genome phenotypic screening of genes.
