PRAME red, technical only
Use
Preferentially expressed antigen in melanoma (PRAME) is a melanoma-associated antigen that acts as a repressor of the retinoic acid receptor signaling pathway. PRAME stains many melanoma subtypes diffusely positive as well as other malignant tumors such as certain sarcomas, carcinomas, and hematolymphoid neoplasms. PRAME is basally expressed in benign testis, ovary, placenta, adrenals, and endometrium tissues.
