EasyWaytoCloneGenesFromaPhageLibrary
Easy Way to Clone The protocol is oriented towards a C. albicans genomic library I made in Lambda Zap II on 7/97.The overall sequence of events is: • Titer and plate out phage • Lift plaques onto filters and prepare them for screening • Make a probe • Hybridize the probe to the filters • Wash the filters and expose to film • Purify putative plaques • Excise plasmid from the des......阅读全文
