Recognises a cluster of proteins between 70-80 kDa, identified as tyrosinase. Occasionally a minor band at 55 kDa is also detected. This mAb shows no cross-reaction with MAGE-1 and tyrosinase-related protein 1, TRP-1/gp75. Tyrosinase is a copper-containing metalloglycoprotein that catalyses several steps in the melanin pigment biosynthetic pathway; the hydroxylation of tyrosine to L-3,4-dihydroxy-phenylalanine (dopa), and the subsequent oxidation of dopa to dopaquinone. Mutations of the tyrosinase gene occur in various forms of albinism. Tyrosinase is one of the targets for cytotoxic T-cell recognition in melanoma patients. Staining of melanomas with this mAb shows tyrosinase in melanotic as well as amelanotic variants. This mAb is a useful marker for melanocytes and melanomas.

ELISA (order Ab without BSA) Flow Cytometry: 0,5-1 µg/million cells in 0,1 ml Immunofluorescence: 1 - 2 µg/ml Immunohistochemistry (FFPE): 0,5 - 1 µg/ml for 30 min at RT (1) Prediluted format: incubate for 30 min at RT (2) Optimal dilution of the Tyrosinase antibody should be determined by the researcher.

1. Staining of formalin-fixed tissues requires boiling tissue sections in 10 mM Tris with 1mM EDTA, pH 9.0, or 10 mM Citrate buffer, pH6,0, for 10 - 20 min followed by cooling at RT for 20 min.
2. The prediluted format is supplied in a dropper bottle and is optimised for use in IHC. After epitope retrieval step (if required), drip mAb solution onto the tissue section and incubate at RT for 30 min.
