View Cart or Continue shopping.
The SJ25C1 monoclonal antibody binds to human CD19, a 95-kDa type I transmembrane glycoprotein in the immunoglobulin superfamily. CD19 forms a signal transduction complex with the complement receptor 2 (CD21), a tetraspanin membrane protein, TAPA-1 (CD81), and Lue 13 to function as a dominant signaling component on the surface of B cells1,2. It is expressed in all phases of B cell development, maturation, and differentiation except at the terminal stage of differentiation, lost in plasma cells3. It is also present on follicular dendritic cells and absent on T cells.
