Description CD19 is a 95 kD type I transmembrane glycoprotein also known as B4. It is a member of the
immunoglobulin superfamily expressed on B-cells (from pro-B to blastoid B cells, absent on
plasma cells) and follicular dendritic cells. CD19 is involved in B cell development,
activation, and differentiation. CD19 forms a complex with CD21 (CR2) and CD81 (TAPA
