Anti-C1QC antibody produced in rabbit

Complement C1q subcomponent subunit C precursor recombinant protein epitope signature tag (PrEST)

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.

C1QC (complement component 1, q subcomponent, C chain) gene encodes the C-chain polypeptide, a major component of the human complement subcomponent C1q. C1q associates with C1r and C1s proenzymes to form the first component of the serum complement system, C1, which functions in the host defense against pathogens. C1q consists of 18 polypeptide chains comprising six A-chains, six B-chains, and six C-chains. Each of these chains contains a collagen-like region at the N-terminus and a globular region at the C-terminus. These chains are localized to chromosome1 and are present as A-C-B. Deficiency of C1q is linked to lupus erythematosus and glomerulonephritis.

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.
