320 - Monoclonal antibody G63
Description: Monoclonal antibodies to MAFA (Mast cell Function-associated Antigen), originally raised against intact rat RBL-2H3 cells. MAFA is a type II membrane glycoprotein, which was shown to inhibit the secretory response to the type 1 Fc? receptor (Fc? RI) stimulus. Binding of G63 antibody to MAFA was shown to enhance this inhibition by enhanced MAFA clustering.
