Abstract:
Objective To identify the species of cultured cells and to detect inter-species cross contamination by polymerase chain reaction (PCR).Methods From references and NCBI database,we outsourced 32 pairs of species-specific primers targeted to genomic DNA of ten common species of cultured cells.Then we screened for optional primers with high specificity and high sensitivity.PCR amplification with these primers,the genomic DNAs isolated from the tested cell line and agarose gel electrophoresis of the PCR products were done.Mixed DNA of 10 species was used as positive-control template,and water as negative-control template.Results Ten pairs of species-specific and highly sensitive primers were selected.By PCR amplification with these primers and agarose gel electrophoresis,we may easily identify the origin of cell lines and find whether the tested cell lines are contaminated by cells of other species.Conclusion This PCR assay provides a simple,rapid,sensitive,and cost-effective method to identify cell species and detect interspecies cross-contamination.
