HPA020432    Human Protein Atlas characterization data

Complement component 3 (C3) is the key component of the complement system. It is referred to as ASP, C3α, C3β, AHUS5, ARMD9, CPAMD1 and HEL-S-62p. C3 is acted upon by C3 convertases, which produces the activated C3b. It is a member of the α2-macroglobulin protein family. It possesses an α- and β-chain of 115 and 75kDa respectively. These together form 13 domains. These domains are divided into single linker (LNK), anaphylatoxin (ANA/C3c), C1r/C1s-UEGF-BMP1 (CUB), C345c and thioester-containing domains (TED), namely eight macroglobulin domains (MG1-MG8).

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. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.

Complement component 3 (C3) is a key fluid-phase protein of the immune system. Complement activation of this gene results in the formation of multiple C3b plasma protein complexes in serum. It helps in recognizing and tags damaged plasma proteins for subsequent removal from the blood without triggering pro-inflammatory functions. The C3 serum levels are associated with angiographic parameters of atherosclerosis.

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.

Corresponding Antigen APREST78222.
