Anti-IGSF8 antibody produced in rabbit

HPA011917    Human Protein Atlas characterization data

IGSF8 (Immunoglobulin superfamily, member 8) is a cell surface IgSF protein with molecular weight of 63kDa. This novel member of Ig superfamily is predominantly expressed in normal human brain, liver and to a lesser extent in the glioblastoma tumors and cell lines. It is expressed on the B, T and natural killer cells but absent in the monocytes, polynuclear cells or platelets.

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.

IGSF8 (Immunoglobulin superfamily, member 8) is majorly involved in the organization of actin cytoskeleton. It connects tetraspanin-enriched microdomains to actin cytoskeleton by the molecular interaction of tetraspanin-tetraspanin. It also binds to α-actinin mediated by PIP2 (Phosphatidylinositol 4,5-bisphosphate) in the regulation of immune synapse formation and T cell activation.

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.
