Identification of positive clones
Web1 nov. 2006 · Identification of positive GATEWAY expression clones when both the pENTRY and pDEST vectors contain the same marker for bacterial selection GATEWAY cloning technology (Invitrogen) takes advantage of bacteriophage λ site-specific recombination. The life cycle of λ alternates between the lytic and lysogenic stages. WebProtocols for Blue-White Screening. The complete protocol of blue-white screening includes 3 important steps: Ligation: ligation of foreign DNA into MCS of the plasmid vector. Transformation: introduction of plasmid vector with foreign DNA insert into competent E. coli. Screening: blue-white screening to identify recombinant bacterial colonies.
