Identification of PINPV--DNA Recombinant Colonies with Sandwich Hybridization
Abstract: The genome of the bacularvirus PINPV was digested completely into sevenfragment (A、B、C、D_1、D_2、E、F) with Hind Ⅲ. These fragments were ligated in vitro with vector pUC18 seperately and used to transform host strainE. coli TG_1. Recombinant colonies were identified with sandwich hybridization.Seven kinds of recombinant colonies containing the PINPV-DNA Hind Ⅲ fra-gments were obtained, but unfortunately the A fragment was less than theoriginal one.
