Anti-PSAP antibody produced in rabbit

产品说明

一般描述

PSAP (prosaposin) is a nonenzymic sphingolipid activator protein. It encodes the precursor of four sphingolipid activator proteins. It is expressed in the extracellular space. PSAP exisits as a fully glycosylated (70kDa) form in the extracellular space. It is secreted from the trans-golgi network (TGN), later transported to the lysosomes as a partially glycosylated (65kDa) protein with high-mannose/hybrid oligosaccharides. Its major composition is complex glycans.

应用

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.

生化/生理作用

PSAP (prosaposin) is mainly involved in lysosomal trafficking. Lysosomal trafficking is mainly modulated by the D domain along with highly conserved C-terminal region of prosaposin. It was first reported that transport of the protein is mediated by sortilin. Later, it has also been postulated that PSAP may covalently aggregate into oligomers and enter into the secretory pathway in oligomerize form.

特点和优势

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.
