Anti-MelanA antibody [DT101 + BC199] (ab731)

Overview

  • Product nameAnti-MelanA antibody [DT101 + BC199]
    See all MelanA primary antibodies
  • Description
    Mouse monoclonal [DT101 + BC199] to MelanA
  • SpecificityThis antibody recognizes a protein of 18kDa, identified at MART-1 (Melanoma Antigen Recognized by T- cells 1) or Melan-A. The MART-1 recognizes a subcellular fraction found in melanosomes. The antibody labels melanomas and tumors showing melanocytic differentiation. It does not mark neoplasms of epithelial origin, lymphomas or mesenchymal tumors. Melan-A is a useful addition to melanoma panels as it is apparently specific for melanocytic lesions. Both HMB-45 and MART-1 are coexpressed in the majority of melanomas, as well as uniquely expressed in certain cases. Studies have shown that MART-1 is more sensitive than HMB-45 when labeling metastatic melanomas.

Applications

Our Abpromise guarantee covers the use of ab731 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
IHC-P 1/50 - 1/100. Perform heat mediated antigen retrieval before commencing with IHC staining protocol. ABC method.
IHC-Fr 1/50 - 1/100. ABC method.
It is sometimes difficult to interpret DAB stained melanomas due to endogenous pigment. We recommend you substitute an AEC or a Fast Red substrate protocol. An avidin biotin blocking may be required for certain types of melanomas.

Target

  • FunctionInvolved in melanosome biogenesis by ensuring the stability of GPR143. Plays a vital role in the expression, stability, trafficking, and processing of melanocyte protein PMEL, which is critical to the formation of stage II melanosomes.
  • Tissue specificityExpression is restricted to melanoma and melanocyte cell lines and retina.
  • Post-translational
    modifications
    Acylated.
  • Cellular localizationEndoplasmic reticulum membrane. Golgi apparatus. Golgi apparatus > trans-Golgi network membrane. Melanosome. Also found in small vesicles and tubules dispersed over the entire cytoplasm. A small fraction of the protein is inserted into the membrane in an inverted orientation. Inversion of membrane topology results in the relocalization of the protein from a predominant Golgi/post-Golgi area to the endoplasmic reticulum. Melanoma cells expressing the protein with an inverted membrane topology are more effectively recognized by specific cytolytic T-lymphocytes than those expressing the protein in its native membrane orientation.
