Abstract

We have established a comprehensive procedure based on the polymerase chain reactian (PCR) to analyze the molecular spectrum of mutatians at the hypoxanthine-guanine phosphoribosyltransferase (hprt) locus in Chinese hamster cells. The procedure includes direct sequencing of PCR-amplified hprt cPHA for locating point mutatians in the expressed coding sequences, multiplex PCR amplification of the hprt exons for screening large deletions, and direct sequencing of PCR-amplified hprt exons and their flanking regions for detecting intronic mutations resulting in mRNA splicing errors. Using this procedure, we have identified different types of mutations among a representative collection of spontaneous and induced HPRT-deficient Chinese hamster cell mutants. This procedure is simple, rapid, accurate, and practical far a comprehensive study of the mutation spectrum in a large number of HPRT-deficient Chinese hamster cell mutants.
