Identification and verification of rodent cell lines by polymerase chain reaction.

ABSTRACT: Cell lines represent valuable tools for basic research and diagnostic applications as well as for the production of biological products such as antibodies or vaccines. For all cell culturists, a well-identified origin of their cell lines as well as the periodic re-examination of their identity should be a basic requirement. We established a simple polymerase chain reaction (PCR) to verify or identify rodent and human cell lines. Since mouse-, rat-, Chinese hamster- and Syrian hamster-derived cell lines represent the most frequently used rodent cell lines, our investigations were focused on these species. Our assay used oligonucleotide primers annealing to sequences within the beta-actin and the beta-globin gene and to repetitive DNA. Primers were designed mostly from intron sequences of th
