Tyrosinase Antibody (T311 + OCA1/812) Summary

Immunogen
Recombinant tyrosinase protein (Uniprot: P14679 )
Localization
Cytoplasmic
Marker
Melanoma Marker
Specificity
Recognizes a cluster of proteins between 70-80kDa, identified as tyrosinase. Occasionally a minor band at 55kDa is also detected. This monoclonal antibody shows no cross-reaction with MAGE-1 and tyrosinase-related protein 1, TRP-1/gp75. Tyrosinase is a copper-containing metalloglycoprotein that catalyzes 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 monoclonal antibody shows tyrosinase in melanotic as well as amelanotic variants. This monoclonal antibody is a useful marker for melanocytes and melanomas.

Applications/Dilutions

Dilutions
  • Flow Cytometry 0.5-1 ug/million cells
  • Immunocytochemistry/Immunofluorescence 1-2 ug/ml
  • Immunofluorescence 1 - 2 ug/ml
  • Immunohistochemistry
  • Immunohistochemistry-Paraffin 1-2 ug/ml
Application Notes
Immunohistochemistry (Formalin-fixed): 1-2ug/ml for 30 minutes at RT. Staining of formalin-fixed tissues requires heating tissue sections in 10mM Tris with 1mM EDTA, pH 9.0, for 45 min at 95C followed by cooling at RT for 20 minutes.
Optimal dilution for a specific application should be determined.

Background

Tyrosinase is a rate-limiting enzyme in the melanin biosynthetic pathway and a complete defect of the enzyme activity caused by homozygous mutations of the tyrosinase gene is well known to result in tyrosinase-negative oculocutaneous albinism (OCA1A) patients who never develop any melanin pigment in the skin, hair and eyes throughout life (1). Tyrosinase catalyzes the first two steps of melanin biosynthesis. Mutations of the TYR gene have been identified in a large number of patients, most of Caucasian ethnic origin, with various forms of type I OCA (2). Type I OCA results from mutations of the gene encoding tyrosinase, the enzyme that catalyzes the first 2 steps of melanin pigment biosynthesis. In type IA (tyrosinase-negative) OCA tyrosinase enzymatic activity is completely absent, and in type IB ("yellow") OCA tyrosinase activity is greatly reduced. More than 80% of the known missense substitutions associated with type I OCA cluster within 2 relatively small regions of the tyrosinase polypeptide, suggesting that these may correspond to functionally important sites within the enzyme (3).
