Description: Melan-A is expressed in the majority of human melanomas as well as in melanocytes. The Melan-A gene, also called MART-1, encodes a melanoma specific antigen recognized by autologous cytotoxic lymphocytes. This antibody reacts with many tumor cells: Benign and malignant adrenocortical tumors, Leydig tumors of the testis, and Sertoli-Leydig ovarian tumors.

Tissue Type: Testis tumors, ovarian tumors, CaC1 melanoma cells and Melanomas. |
Fixation: Formalin fixed paraffin sections, acetone fixed frozen sections, or cytospin preparations. |
Positive Control: Testis tumors, ovarian tumors, CaC1 melanoma cells and Melanomas. |
Negative Control: Omit primary antibody, isotype control, absorption control |
Blocking: 2-5% normal serum to reduce unspecific background staining; 0.5-3% H2O2 to block endogenous peroxidase activity; avidin/biotin to block endogenous biotin activity if necessary |
Melan-A/MART-1 (Clone M2-7C10 + M2-9E3, Labvision, Cat# MS-716-P1) also works well at 1:100 dilution on paraffin sections with Citrate Buffer Method.
