Abstract
In vitro selection of proteins from cDNA libraries using display technologies, such as the in vitro virus method, is a powerful means for the discovery of novel protein interactions. After iterative screening, selected proteins are usually identified and evaluated by cloning and sequencing analysis. Previously we applied real-time PCR for evaluation of the sequences obtained on in vitro virus screening. Here, we have presented additional data regarding monitoring of the process of enrichment of selected clones in each round of selection and elimination of false positives by real-time PCR, and have also discussed the utility of the novel method. This approach should also be applicable to other display technologies.
