Anti-MS4A1 antibody produced in rabbit

产品说明

一般描述

The gene MS4A1 (membrane spanning 4-domains A1) is also referred to as CD20 and is expressed on the surface of human B lymphocytes and to some extent on a small subset of T cells. The 33 to 35kDa, nonglycosylated protein has 4 membrane-spanning domains with both the amino and carboxy termini of the protein localized to the cytoplasm. The gene is mapped to human chromosome 11q12-13.

免疫原

B-lymphocyte antigen CD20 recombinant protein epitope signature tag (PrEST)

应用

All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org)and as a result, are supported by the most extensive characterization in the industry.

The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link.

生化/生理作用

The gene MS4A1 (membrane spanning 4-domains A1) encodes a protein belonging to the membrane-spanning 4A gene family that participates in the development and cell cycle progression in B-cells. It has been found to interact with proteins, such as transmembrane adapter protein p75/80, CD40, and major histocompatibility complex class II proteins (MHC II). It may participate in Ca²⁺ influx across plasma membranes, maintenance of Ca²⁺ concentration, and activation of B-cells. The MS4A1 protein activates Src leading to rapid phosphorylation of phospholipase C-γ1 (PLC-γ1) and PLC-γ2, in turn activating caspase-3 signaling of apoptosis.

特点和优势

Prestige Antibodies^® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies^® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:

• IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
• Protein array of 364 human recombinant protein fragments.
