Tissue Cross-Reactivity Studies

Guidelines issued by the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA) for the development of therapeutic antibodies and related products recommend their testing for tissue cross reactivity (TCR) on a range of human tissues.

Precision for Medicine’s scientific team can perform TCR screening studies using frozen tissue microarrays, or fully good laboratory practice (GLP)-compliant TCR studies suitable for Investigational New Drug (IND) submission.
