This antibody recognizes a protein doublet of 20-22kDa, identified as MART-1 (Melanoma Antigen Recognized by T cells 1) or Melan-A. MART-1 is a melanocyte differentiation antigen recognized by autologous cytotoxic T lymphocytes. There are seven other melanoma associated antigens recognized by autologous cytotoxic T cells: MAGE-1, MAGE-3, tyrosinase, gp100, gp75, BAGE-1, and GAGE-1. Subcellular fractionation shows that MART-1 is present in melanosomes and endoplasmic reticulum. This MART-1 antibody labels melanomas and other tumors showing melanocytic differentiation. It is also a useful positive-marker for angiomyolipomas. The antibody does not stain tumor cells of epithelial, lymphoid, glial, or mesenchymal origin.

ELISA: order BSA-free format for coating Flow Cytometry: 0.5-1 ug/million cells IF: 1-2 ug/ml WB: 0.5-1 ug/ml IP: 0.5-1ug/500ug protein lysate IHC (FFPE): 0.5-1 ug/ml for 30 minutes at RT (1) Prediluted format : incubate for 30 min at RT (2) The concentration stated for each application is a general starting point. Variations in protocols, secondaries and substrates may require the Melan-A antibody to be titered up or down for optimal performance.

1. Staining of formalin-fixed tissues is enhanced by boiling tissue sections in 10mM Citrate Buffer, pH 6.0, for 10-20 min followed by cooling at RT for 20 minutes.
2. The prediluted format is supplied in a dropper bottle and is optimized for use in IHC. After epitope retrieval step (if required), drip mAb solution onto the tissue section and incubate at RT for 30 min.
