The characterization of three monkey kidney cell lines.

Three monkey kidney cell lines, Vero, GL-V3 and MA-104 were subjected to karyological analysis to determine their chromosomal stability and to confirm their species of origin. Although the lines were shown to be relatively stable throughout all of the passage levels that were tested, the species of origin of one of them was found to be different from that claimed by the originators. This finding was supported by data from isoenzyme studies.
