STR Database for Human Cell Lines
As part of our continuing efforts to fully characterize and authenticate the cell lines in our collection, ATCC is developing a comprehensive database of DNA fingerprints of STR (short tandem repeat) loci for all of our human cell lines.
STR loci are among the most informative polymorphic markers in the genome. The fingerprinting process used at ATCC involves simultaneously amplifying eight STR loci and the amelogenin gene in a multiplex PCR reaction (Promega PowerPlex® 1.2 system) which allows for discrimination of fewer than 1 in 108 individuals (Lins, A.M., et al. J. Forensic Sci. 43: 1168-1180, 1998). The amplicons are separated by electrophoresis and analyzed using Genotyper® 2.0 software from Applied Biosystems. Each peak in the resulting electropherogram represents an allele that is alphanumerically scored and entered into our database.
Below is the alphanumeric data for each cell line we have characterized. This list will be updated monthly as new information is generated until all of our human cell lines are listed. As in the past, when we find an inconsistency in the fingerprint of a cell line (i.e., the fingerprint is similar or identical to that of an unrelated cell line) we will post a note at Misidentified Cell Lines. We fully expect this database will initiate and facilitate discussions on cell line authenticity.
We are providing this data to the scientific community as a service to help ensure the quality and integrity of research. You can now fingerprint your cells and compare them to our cells. We anticipate that this information will become the standard for identifying human cell lines. If you have any questions about STR loci or this database, please contact a technical service representative. |
