Tyrosinase (TYR, LB24 AB, LB24-AB, Monophenol Monooxygenase, Oculocutaneous Albinism IA, OCA1A, OCAIA, SK29 AB, SK29-AB, Tumor Rejection Antigen AB) (BSA & Azide Free) (HRP)

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 antibody showed tyrosinase in melanotic as well as amelanotic variants (1). This antibody is a useful marker for melanocytes and melanomas.

Applications:
Suitable for use in Immunocytochemistry, Western Blot, Immunofluorescence and Immunohistochemistry. Other applications have not been tested.

Recommended Dilutions:
Immunohistochemistry (formalin/paraffin): Staining of formalin-fixed tissues requires boiling tissue sections in 1mM EDTA, pH 8.0, for 10-20 minutes followed by cooling at RT for 20 minutes.
Optimal dilutions to be determined by the researcher.

Positive Control:
Melanoma cell lines and Melanoma

Storage and Stability:
Store product at 4°C if to be used immediately within two weeks. For long-term storage, aliquot to avoid repeated freezing and thawing and store at -20°C. Aliquots are stable at -20°C for 12 months after receipt. Dilute required amount only prior to immediate use. Further dilutions can be made in assay buffer. Note: Sodium azide is a potent inhibitor of peroxidase and should not be added to HRP conjugates.
For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.

Note: Applications are based on unconjugated antibody.
