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.

Actions biochimiques/physiologiques

Pregnancy-associated plasma protein-A (PAPPA) is an insulin-like growth factor binding protein (IGFBP) protease. It is characterized as a zinc-binding matrix metalloproteinase that is abundantly expressed in eroded and ruptured plaques. It may function as a marker of plaque destabilization. In presence of IGF, PAPP-A particularly cleaves IGF-binding protein (IGFBP)-4, one of six antagonists of IGF action, which leads to the release of IGF bound to IGFBP-4.

Caractéristiques et avantages

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.

Insulin-like growth factors (IGFs), IGF binding proteins (IGFBPs), and IGFBP proteases are important in ovarian function. IGFs stimulate granulosa steroidogenesis, an effect that is inhibited by IGFBP-4 and augmented by IGFBP-4 proteolysis. We have recently identified the IGFBP-4 protease in

Pregnancy-associated plasma protein-A (PAPPA), also known as pappalysin, is a member of the insulin-like growth factor (IGF) family. PAPPA acts as a protease, cleaving IGF inhibitors, i.e., IGF binding proteins (IGFBPs), thereby setting free IGFs. The insulin/IGF-axis is involved in

Pregnancy-associated plasma protein-A (PAPP-A), originally known from human pregnancy serum, has recently been demonstrated to be a metzincin superfamily metalloproteinase involved in normal and pathological insulin-like growth factor (IGF) physiology.
