Gene Information

human ... CD19(930)

Specificity

The CD19 antigen (90 kDa) is expressed from the earliest stages of B-progenitor development, on all peripheral B cells including germinal centre B cells and all B cell lines and B cell leukaemias tested. T cell and monocytic cell lines are negative and the antigen is lost on B cell maturations to plasma cells. The antigen is a type I integral membrane glycoprotein whose in vitro inhibition will influence B cell activation and proliferation.

Application

Anti-CD19 Antibody, clone HD37 detects level of CD19 & has been published & validated for use in FC, IP, IH.
Identification of CD19 positive B lymphocytes and malignant B cells by indirect immunofluorescence staining

Leukaemia and lymphoma phenotyping

Identification of normal and malignant CD19 positive B lymphocytes in cryostat frozen sections

Immunoprecipitation of the CD19 antigen

Studies of the CD19/21 complex in B cell activation and the control of B cell development

CD19 and CD21 (CR2) are co-receptors found on B-cells and various B-cell lymphomas, including non-Hodgkin lymphoma. To evaluate their suitability as targets for therapy of such lymphomas using internalization-dependent antibody-drug conjugates [such as antibody-4-(N-maleimidomethyl)cyclohexane-1-carboxylate, (N2'-deacetyl-N2'-(3-mercapto-1-oxopropyl)-maytansine) (MCC-DM1) conjugates, which require lysosomal

Low-grade MALT-type lymphomas are malignancies of mucosal marginal-zone B cells and preceded by reactive inflammatory lymphoid tissue. Experimental observations suggest that antigen and CD40 Ligand act during cognate T/B cell interaction and are crucial for germinal center B-cell maturation generating
