免疫原

Cystathionine beta-synthase recombinant protein epitope signature tag (PrEST)

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

CBS (cystathionine-β-synthase) encodes a heme containing protein that catalyzes the conversion of serine and homocysteine to cystathionine, which is the first step in the transsulfuration pathway. It acts as a homotetramer and uses pyridoxal phosphate as a cofactor. S-adenosylmethionine (SAM) binding to CBS activates catalytic domain of CBS. Defects in this gene lead to deficiency of CBS causing homocystinuria, which is characterized by increased levels of the toxic metabolite homocysteine. Higher levels of homocysteine are associated with increased risk for cardiovascular diseases, Alzheimer′s disease and with neural tube defects. Polymorphism in it is also linked to bipolar disorder. Presence of CBS in human fallopian tube epithelium is crucial for production of gaseotransmitter, hydrogen sulphide, which relaxes the spontaneous contraction of the human oviduct. It is up-regulated in colon cancer cells and supports tumor growth and stimulates angiogenesis and vasorelaxation.

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.
