Cell line misidentification, contamination, and poor annotation affect scientific reproducibility.  STR profiling aids in the detection of cell lines that are misidentified, cross-contaminated, or have genetically drifted - any of which can invalidate research results.  With WiCell’s Short Tandem Repeat (STR) testing you can be confident in the material used for your research.  In addition WiCell's STR testing can also be used to address the NIH’s new grant application guidance regarding the authentication of key biological resources.
