  • About DDC

Cell lines are often used in biomedical research to investigate disease pathways and therapies.

In late 2007, an open letter by a group of scientists led by Dr. Roland Nardone spurred the National Institutes of Health (NIH) to recommend authenticating cell lines in scientific studies.

In early 2012, the ATCC issued its standard to address the problem of cell line misidentification and "delineate a standardized, universally applicable method for authenticating new and established human cell lines and human primary tissue used in research."

Studies have shown an alarming percentage of human cell lines, those purchased from commercial repositories and primary cell lines, are contaminated or misidentified. Poor cell culture technique, shared equipment and poor quality control in a laboratory can all contribute to the misidentification and contamination issues. In addition, genetic instability of some cell lines can result in changes at the DNA level that can compromise research results. Articles published on these topics indicate as much as 20 to 33 percent of all cell lines are misidentified or contaminated, but there is a simple and affordable solution.

DDC Medical, a division of DNA Diagnostics Center (DDC), one of the world’s largest DNA laboratories, offers Human Cell Line Authentication and Mycoplasma Detection services.

Peer review Journals throughout the research community recommends Cell Line Authentication and Mycoplasma Detection as part of the publication process. Grant providers are also aware of the issue and requiring Cell Line Authentication and Mycoplasma Detection ensures a sound investment.

   • When a new line is first established or purchased
   • As a control measure at the start of a new study and concluding a study
   • At least once every 6 months in active culture
   • Before freezing down for storage

Human Cell Line and Primary Cell Line Authentication

DDC Medical is committed to assisting the research community with proper cell line documentation through its Cell Line Authentication and Mycoplasma Detection services. We offer the most comprehensive testing available. DDC Medical uses DNA STR analysis, examining 17 highly polymorphic genetic markers, more than twice than is recommended. A DNA profile is generated, uniquely identifying the cell line. Authentication will ensure the research has been conducted using the correct cells, maximizing reliable results, supporting publication efforts and reducing the risk of wasted time and resources. A researchers reputation could also be adversely affected by publishing results from contaminated cell lines.

DDC uses STR (Short Tandem Repeat) Analysis in Cell Line Authentication

The DNA profile generated for Cell Line Authentication utilizes STR analysis of a number of highly polymorphic unlinked loci. Each locus is characterized by a motif of repeat units typically 4 bases in length. The number of repeats detected in a DNA fragment identifies each allele. For example, if the designation at the D5S818 locus is 14, 16, two DNA fragments were detected; one with 14 repeats and one with 16 repeats. The loci used for Cell Line Authentication are utilized for human identification for paternity and forensic analysis and are not designed to detect non-human DNA. Cell lines established from different human sources will possess different DNA profiles.

Mycoplasma Detection

Authenticating cell cultures is a process that not only verifies the identity of the cell line, but also rules out any contaminants. Mycoplasma is one of the most prevalent contaminating agents in cell culture. Unlike most bacterial and fungal contaminants, which are easily detected by changes in visual appearance of the culture, mycoplasma contamination cannot be detected without further analysis.

Mycoplasma are parasitic, unicellular organisms that have the ability to induce chromosomal aberrations and metabolic changes, as well as alter a cell line's growth pattern, in some cases leading to the death of the cell line. These changes can affect the experimental results derived from infected cell lines.

DDC’s Mycoplasma Detection Test

To rule out mycoplasma in your cell cultures, DDC Medical offers a DNA PCR detection test that will screen for 19 species, including the 6 most common contaminants found in cell cultures. DDC Medical tests for all of the most common contaminants and 95% of all mycoplasma contaminants. The Mycoplasma Detection test has a sensitivity of 3 to 5 femtograms of mycoplasma DNA or approximately 5 mycoplasma genomes per micro liter.
