Tissue Cross-Reactivity Studies

TCR screening studies or GLP-compliant TCR studies suitable for IND submission

Precision for Medicine’s scientific team can perform TCR screening studies using frozen tissue microarrays or GLP–compliant TCR studies suitable for Investigational New Drug (IND) submission. Guidelines issued by the US 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.

Tailored methodology for biotherapeutic tissue cross-reactivity studies

Precision for Medicine’s unique combination of research services and comprehensive tissue bank form the pillars of our TCR Services.
