BioCoreUSA provides normal, malignant or metastatic tissue array or tissue microarray (TMA) which can be utilized to validate clinical relevance of potential biological targets in the development of therapeutics, diagnostics and study new protein markers and genes. TMA contains multiple tissue samples with DNA,RNA and protein. The advantage of TMA lies in the small size, and the tissue morphology and genetic characteristics are similar in the serial TMA tissue sections. Therefore, it provides a high-throughput methods for the fast analysis of molecular markers associated with disease diagnosis, prognosis and therapeutics in patients. BioCoreUSA also provides custom tissue array as well as the immunohistochemistry (IHC) staining service.
