MART-1 / Melan-A Antibody

SKU: orb248349

Description

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.

Images & Validation

• Tested Applications: FACS, IF, IHC-P, WB
• Dilution range: Flow cytometry: 1-2ug/million cells,Immunofluorescence: 1-2ug/ml,Western blot: 1-2ug/ml,Immunohistochemistry (FFPE): 1-2ug/ml for 30 min at RT
• Reactivity: Human, Mouse, Rat
• Application Notes:
  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 pH 9 10mM Tris with 1mM EDTA 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.
