It is a fact that cross-contamination and misidentification of mammalian cell cultures is widespread. An incredible high number of 15-20% of all cell line based biomedical research is affected by misidentified cell lines. Therefore, establishing a cell line’s identity through STR profiling is essential to conducting valid and re-producible research. Moreover, more and more journals (not only the high-impact ones!) are requesting the authentication of cell lines as prerequisite for acceptance of manuscripts.
Microsynth has over 10 years of experience in genotyping and offers an easy-to-use service for human, mouse, rat, and dog cell lines.
Mouse cells typed with 18 mice specific STR markers from Almeida et al. 2019.
Rat cells typed with 14 rat specific STR markers and one sex specific marker
Dog cells typed with 11 dog specific STR markers.
Easy-to-use
Ship your cell line(s) at room temperature. Microsynth has developed a protocol which eliminates costly shipment of your cell line(s) on dry ice.
Use our cost-free pickup service and drop your cell line(s) into one of our numerous collection boxes in Europe. Alternatively send us your cell line(s) with your preferred postal service at room temperature.
Reduce Your Risk
Fast and reliable cell line authentication by Microsynth a provider with many years of experience
Don't risk working with misidentified or cross-contaminated cell lines
Convenient
Multiple organisms are available. In cooperation with our subsidiary ecogenics GmbH, we can develop high-quality microsatellite markers for virtually any organisms.
Useful add on services at an extra charge:
Database comparison of the DNA profile on Cellosaurus for human and mouse
Mycoplasma contamination testing of cell culture supernatant
How it Works
Collect 1.0-5.0 mio cells and wash the cell pellet twice in PBS or another appropriate buffer. Resuspense cell pellet in 0.5 ml of 70-90% ethanol and transfer to 1.5 ml screw cap tube (no cryo-tube) . If you want to send us isolated DNA, please provide ≥50 μl gDNA at a concentration of 50 ng/μl in Tris or low-EDTA buffer (10 mM Tris, 0.1 mM EDTA).
