Highlighted Antibody - Melan A Clone BS52

Melan A (MART-1) is a transmembrane protein which is expressed in skin melanocytes and melanocyte lineages, and is ecognised by autologous cytotoxic T lymphocytes.


This antibody is useful for the identification of melanomas and it should be included in standard melanoma diagnostic panels. It does not cross react with cells of adrenal cortex.


This antibody provides truly optimal staining and as with all our antibodies we provide a 100% guarantee, so trying it really is risk free.
