ANTI-CD8B (C15-1452-159)

General description

Human CD8 (cluster of differentiation 8 or CD8b molecule) is expected to have disulfide-linked homodimers and homomultimers of a single polypeptide chain similar to that of mouse and rat CD8 alpha. It belongs to the Ig gene superfamily. CD80 has NH₂-terminal domains similar to Ig variable (V) regions and joining (J) segments. CD8 is a glycoprotein that is expressed in thymocytes, mature T cells and natural killer (NK) cells. CD8B is located on human chromosome 2p11.

CD8b molecule

Application

All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project 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. We also provide Prestige Antibodies^® protocols and other useful information.

Biochem/physiol Actions

The CD8 (cluster of differentiation 8 or CD8b molecule) helps to identify the monomorphic determinants on major histocompatibility complex (MHC) class I antigens, and in signal transduction at the time of T-cell activation.

Features and Benefits

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.

Linkage

Corresponding Antigen APREST90687.

Physical form

Solution in phosphate buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide.
