Description | The antibody A103 is suitable for the detection of Melan-A antigen (syn. MART-1) in cells of melanoic origin. The antibody will label 80-90% of metastasing malign melanoma (1, 6). Melan-A-negative melanoma usually are of the spindle cell or desmoblastic type. The antibody also reacts positive with angiomyolipoma (4) and steroid hormone producing cells of the adrenal gland, ovary, testis and especially with carcinoma of these organs. Melan-A is a melanoma specific antigen, which is detected by cytotoxic T-cells. It is exprimed by benign naevi and melanoma cells. 20-22 kDA Melan-A protein, no cross-reactivity to MAGE-1 and Tyrosinase. |
