DNA fingerprint method of the cultured cells

: DNA fingerprint method is very available not only to examine the cross-contamination of cultured cell lines and their origins and but to know the somatic mutation frequency in the cultured cells by exposure of radiation and chemicals. The method for DNA fingerprint was grouped in the following four types in term of probe; multilocus minisatellite probe, simple sequence repeat probe, locus specific minisatellite probe and repeat unit sequence variation in minisatellites.
