DDC, One of the Largest DNA Testing Companies Worldwide, Supports National DNA Testing Standard for Tissue Culture Authentication

Share Article

In line with the new National Standard for Authentication of Human Cell lines, DDC has developed a Cell Line Authentication Service that follows the National Standard by providing DNA testing services to identify human cells.

We are pleased that the scientific community has developed standards for testing cell lines. The testing recommended by the new National Standard, STR analysis, is a core strength of DDC.

DDC(DNA Diagnostics Center), one of the largest DNA testing companies in the world, announces its support for the new National Standard requiring DNA testing for tissue culture authentication. The National Standard was developed for a number of reasons, including the fact that tissue cell cultures used in a variety of biomedical research areas are often misidentified. This misidentification leads to inappropriate conclusions, withdrawal of scientific papers, and wasted resources. This knowledge has spurred the scientific community to develop standards to address this situation.

A recent publication by the American Type Culture Collection Standards Development Organization (ATCC SDO), ASN-0002: “Authentication of Human Cell Lines: Standardization of STR Profiling” discusses the need to use DNA testing methods to verify the authenticity of human cell lines used in a wide variety of research activities. This consensus National Standard will have a profound impact on researchers involved with basic cell biology research, drug discovery, stem cell research, and translational medicine. In addition, it should have a significant impact on the issue of tissue cell line misidentification.

In line with the new National Standard for Authentication of Human Cell lines, DDC has developed a Cell Line Authentication Service that follows the National Standard by providing DNA testing services to identify human cells. According to Peter Vitulli, President and CEO of DDC, “We are pleased that the scientific community has developed standards for testing cell lines. The testing recommended by the new National Standard, STR analysis, is a core strength of DDC, and over the past year we have been working with researchers, biotechnology companies, and drug development leaders to provide the testing services to authenticate their cell lines.”

In addition to cell line authentication services, DDC provides testing to identify contamination by other human cell lines as well as bacteria like mycoplasma, a common contaminant of cell culture. DDC is also able to provide species identification for researchers that work with cell lines from multiple species. Samples can be provided to DDC in the form of cell pellets, isolated DNA, or cells spotted to FTA cards with testing completed in 5 days. Many scientific peer review journals now require cell line authentication in order to publish and this trend is likely to increase.
