The cell line authentication testing division of Labcorp (formerly known as Genetica Cell Line Testing - a LabCorp brand), provides reliable, fast and affordable authentication of human cancer cell lines, stem cell lines, xenografts, and more utilizing STR DNA technology; current clients include major research and cancer institutions, pharmaceutical and biotechnology companies within the United States and throughout the world.
Inadvertent cell line contamination has been a major problem for biomedical researchers with estimates that 18-36% of all cell lines are either misidentified or cross-contaminated with another cell line ; cell line integrity is of utmost importance since the validity of the data obtained often depends on the identity of the cell line or stem cells used. The National Institutes of Health  recommends validation of cell lines for grant applications and many journals such as those published by the American Association for Cancer Research (AACR)  and Nature have guidelines for cell line authentication prior to publication .
The short tandem repeat DNA profiling (STR DNA profiling, STR DNA typing, STR DNA test, and also known as DNA fingerprinting) offers the greatest value for cell line identity verification (cell line authentication). The process of obtaining a DNA profile using highly polymorphic STR repeats includes the isolation of DNA from a human cell line or other research specimen, the amplification of targeted areas of that DNA, and analysis of the amplified product using a genetic analyzer. STR DNA typing generates reproducible data in a format suitable to reference cell line database or patient sample comparison. Labcorp's laboratory procedures for cell line authentication comply with the guidelines set forth by the American Type Culture Collection (ATCC) SDO Workgroup ASN-0002 Standards document , as well as with the requirements of other leading scientific organizations.
Labcorp provides reliable, fast, and affordable human cell line authentication services, using STR DNA typing to assist the scientific community in accurate identification of specimens used in research and drug development. Our standard human cell line authentication test involves generating STR DNA profiles of the submitted cell lines or other research specimens for 15 independent genetic sites and amelogenin [the sex identity locus].
NEW! All of our human cell line authentication report options include a single MOUSE marker for the detection of mouse DNA contamination, especially helpful for researchers who are using mouse/human xenograft models and/or human and mouse cell lines simultaneously. The test can also be used to confirm that a mouse cell line is NOT cross-contaminated with a human cell line or confirmation of the presence of mouse cells. We can detect as low as 0.5% contaminating mouse DNA. Additional human genetic STR sites may also be tested [contact us for details].
