Popis: | Iterative screening of expressed protein libraries using fluorescence-activated cell sorting (FACS) typically involves culturing the pooled clones after each sort. In these experiments, if cell viability is compromised by the sort conditions and/or expression of the target protein(s), rescue PCR provides an alternative to culturing but requires re-cloning and can introduce amplification bias. We have optimized a simple protocol using commercially available reagents to directly recover plasmid DNA from sorted cells for subsequent transformation. We tested our protocol with 2 different screening systems in which 60% of the sorted cell population was recovered. |
