CD19 Antibody Product Information

Immunogen :

Recombinant Human CD19 Protein (Catalog #11880-H08H)

Antibody Type : Mouse Monoclonal Antibody ( Mouse mAb Service Platform )

Clone ID :


Ig Type :

Mouse IgG1

Formulation : 0.2 μm filtered solution in PBS, 5% trehalose may be added in some batches. Please read the hardcopy of COA or contact our customer service to confirm the formulation.
Preparation :

This antibody was produced from a hybridoma resulting from the fusion of a mouse myeloma with B cells obtained from a mouse immunized with purified, recombinant Human CD19 (rh CD19; Catalog#11880-H08H; Met 1-Lys 291; P15391). The IgG fraction of the cell culture supernatant was purified by Protein A affinity chromatography.

CD19 Antibody Background

B-lymphocyte antigen CD19, also known as CD19, is a single-pass type I membrane protein which contains two Ig-like C2-type (immunoglobulin-like) domains. CD19 forms a complex with CD21, CD81 and CD225 in the membrane of mature B cells. It interacts with VAV. It interacts with GRB2 and SOS when phosphorylated on Tyr-348 and/or Tyr-378. CD19 also interacts with PLCG2 when phosphorylated on Tyr-409. CD19 is an important pan B cell marker and co-stimulatory protein in humans and mice. CD19 is a hallmark differentiation antigen of the B cell lineage and positively regulates antigen receptor signal transduction in mature B cells. CD19 defines signaling thresholds for the Ag receptor as well as other cell surface receptors that regulate B lymphocyte selection, activation, and differentiation. Defects in CD19 are a cause of hypogammaglobulinemia.
