RESUMO
Objective To establish a high throughput general multiple competitive polymerase chain reaction ( cPCR) detecting method of copy number variations ( CNVs) for the population of chromosome 1 substitution strains from wild mice.Method The selected 14 loci, including 11 CNVs on chromosome 1 and internal control loci on other three chromosmes (Chr 7, Chr 19 and Chr X), were detected based on the universal fluorescent primer multiple competitive pol-ymerase chain reaction.All specific cloned plasmids were constructed as competitors.Results Altogether 11 CNVs were designed in one panel, and the copy of Chr X accurately reflects the gender.Conclusions A rapid and high-throughput fluorescent multiplex cPCR assay is established which can be used for detection of copy number variations on chromosome 1 in mice.
