Using degenerate oligonucleotide primers for conserved regions of HSP60, a 0.6 kilobase fragment of Clostridium perfringens DNA was amplified by the polymerase chain reaction. The amplified fragment was used as a probe to isolate a genomic clone containing the C. perfringens HSP60 operon. The clone contained two open reading frames homologous to the GroES and GroEL (or HSP60) family of bacterial and eukaryotic proteins as well as other upstream and downstream sequences. The approach described here, employing this set of degenerate oligonucleotide primers, could be used to clone HSP60 gene/cDNA from any species.
