Clone Host Grade Applications Monoclonal Mouse Affinity Purified IH IC FC

CD19 is a type I transmembrane glycoprotein important in B-lymphocyte signal transduction.1 Together with CD21, CD81, and beta 1 integrin, it is a part of the B-lymphocyte signaling complex, which regulates B-cell activation and differentiation.2 Originally identified as B4, CD19 is a pan B-cell antigen expressed from the B-cell progenitor stage where rearrangement of immunoglobulin genes takes place, to the terminal stage of B-cell differentiation into plasma cells. CD19 is detected on follicular dendritic cells and malignant B-cells.
