Anti-btn3a3

Not available outside of the UK & Ireland.

Application

Anti-BTN3A3 antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project . Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.

Biochem/physiol Actions

BTN3A3 (butyrophilin, subfamily 3, member A3) gene encodes a member of the butyrophilin (BTN) family, the members of which are major histocompatibility complex (MHC)-associated genes. These genes encode type I membrane proteins containing two extracellular immunoglobulin (Ig) domains and an intracellular B30.2 (PRYSPRY) domain. BTN3A3 is expressed on endothelial cells, in the membrane layer surrounding milk fat-secreting droplet from mammary epithelial cells, on immune cells, and on some tumor cell lines. It may be involved in the proliferation of CD₄⁺ and CD₈⁺ and in the cytokine secretion by T-cells. It may function as a co-stimulatory molecule on CD₄⁺ T cells and NK (Natural Killer) cells.

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.
