Catalog No. ABIN94017

Product Details anti-CD19 Antibody (APC)

Target: CD19 (CD19 Molecule (CD19))

Reactivity: Human

Host: Mouse

Clonality: Monoclonal

Conjugate: This CD19 antibody is conjugated to APC

Application: Flow Cytometry (FACS)

Specificity: The antibody LT19 reacts with an extracellular epitope of CD19 (B4), a 95 kDa type I transmembrane glycoprotein (immunoglobulin superfamily) expressed on B lymphocytes and follicular dendritic cells, it is lost on plasma cells.

Alternative Name: CD19 (CD19 Products)

Background: CD19 Molecule,CD19 is a transmembrane glycoprotein of Ig superfamily expressed by B cells from the time of heavy chain rearrangement until plasma cell differentiation. It forms a tetrameric complex with CD21 (complement receptor type 2), CD81 (TAPA-1) and Leu13. Together with BCR (B cell antigen receptor), this complex signals to decrease B cell treshold for activation by the antigen. Besides being signal-amplifying coreceptor for BCR, CD19 can also signal independently of BCR coligation and it turns out to be a central regulatory component upon which multiple signaling pathways converge. Mutation of the CD19 gene results in hypogammaglobulinemia, whereas CD19 overexpression causes B cell hyperactivity.,B4, Leu-12, CVID3
