Anti-CD19/ B4/ CVID3 antibody for FACS & in-vivo assay| GMab

Pre-made anti-CD19 benchmark inhibitory monoclonal antibody(mab, blocking antibody inhibitor) is expressed by mammalian cell line as a benchmark antibody for cell culture, FACS, ELISA or other affinity binding assay or functional assay development, animal model development, PK/PD model development (Pharmacokinetics & Pharmacodynamic). The anti-CD19 mab is expressed and produced by mammalian cell line as a benchmark reference therapeutic antibody for biological drug discovery items including cell culture, assay development, animal model development, PK/PD model development (Pharmacokinetics & Pharmacodynamic) and mechanism of action (MOA) research. The target: CD19, gene name: CD19, also named as B4, CVID3. This gene encodes a member of the immunoglobulin gene superfamily. Expression of this cell surface protein is restricted to B cell lymphocytes. This protein is a reliable marker for pre-B cells but its expression diminishes during terminal B cell differentiation in antibody secreting plasma cells. The protein has two N-terminal extracellular Ig-like domains separated by a non-Ig-like domain, a hydrophobic transmembrane domain, and a large C-terminal cytoplasmic domain. This protein forms a complex with several membrane proteins including complement receptor type 2 (CD21) and tetraspanin (CD81) and this complex reduces the threshold for antigen-initiated B cell activation. Activation of this B-cell antigen receptor complex activates the phosphatidylinositol 3-kinase signalling pathway and the subsequent release of intracellular stores of calcium ions. This protein is a target of chimeric antigen receptor (CAR) T-cells used in the treatment of lymphoblastic leukemia. Mutations in this gene are associated with the disease common variable immunodeficiency 3 (CVID3) which results in a failure of B-cell differentiation and impaired secretion of immunoglobulins. CVID3 is characterized by hypogammaglobulinemia, an inability to mount an antibody response to antigen, and recurrent bacterial infections. Alternative splicing results in multiple transcript variants encoding distinct isoforms. [provided by RefSeq, Jul 2020].
