General description

SERPINB2 (serpin peptidase inhibitor B2) is a member of a large family of proteins called serine protease inhibitors (serpins), the members of which are structurally related. It has a constitutive expression in only certain cell types such as, trophoblasts, neurons, pre-adipocytes, macrophages and keratinocytes. When localized intracellularly, it has a molecular weight of 47kDa, and is non-glycosylated. The secreted form is 60kDa, and is glycosylated. It has a C-D loop, which are α-helices acting as bridges between domains.

Immunogen

Plasminogen activator inhibitor 2 precursor recombinant protein epitope signature tag (PrEST)

Application

Anti-SERPINB2 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.
Applications in which this antibody has been used successfully, and the associated peer-reviewed papers, are given below.

Biochem/physiol Actions

SERPINB2 (serpin peptidase inhibitor B2) functions as a suppressor of urokinase type plasminogen activator. It is involved in the survival of macrophages, differentiation of keratinocytes and monocytes, signaling pathways, apoptosis and cellular protection. It also has an immunomodulatory role, and aberrant expression of this protein is linked to asthma, pre-eclampsia, periodontal disease, and cancer. Its expression is induced by the carcinogen PMA (phorbol 12-myristate 13-acetate) in multiple cell types such as, monocytic lineage cells. In endothelial cells, it binds to proteasome complex, and thus, affects its activity. As proteasome activity determines the apoptotic fate of cells, elevated expression of this protein in endothelial cells might favor apoptosis. The expression of this protein is elevated in cervical cancer, and this is linked to high-risk human papillomavirus (HPV) and cervical lesion grade.

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.
