Clone TA99 is a mouse monoclonal antibody that reacts with tyrosinase-related protein 1 (TRP1), a 75kDa differentiation-related human glycoprotein (gp75), formerly referred to as pigmentation-associated antigen (PAA). It is expressed by pigmented melanoma cells and cultured melanocytes. TRP1 is involved in the pigmentation machinery of melanocytes and can be used as a differentiation marker.
This antibody was derived in 1985 by injection of whole human melanoma cells (SK-MEL-23) into mice. Splenocytes from these immunized mice were fused with NS-1 cells to generate hybridomas producing anti-TRP1 antibodies.
