Gene Information

human ... C1S(716)

General description

The gene complement component 1 subcomponent s (C1S) is mapped to human chromosome 12p13.2. The protein contains a CUB1 (C1r/C1s, Uegf, Bmp1)-EGF (Epidermal growth factor-like)-CUB2 region, two complement control protein modules (CCP1 and CCP2) and a serine protease (SP) domain.

Immunogen

Complement C1s subcomponent precursor recombinant protein epitope signature tag (PrEST)

Application

Anti-C1S antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project . Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige. The antibody has been used for bead array immunoassay.

Biochem/physiol Actions

Complement component 1 subcomponent s (C1S) is a subcomponent of C1, the first component of the complement system. The complement system is a first line of innate immune defense in cells. C1S is a serine protease. Activated C1S participates in immune response by binding and cleaving the effector molecule complement component-4 (C4). The CUB1 (C1r/C1s, Uegf, Bmp1)-EGF (Epidermal growth factor-like) region of C1S is responsible for mediating interaction between C1S and other components of C1 (C1R and C1Q). Absence of C1S is associated with autoimmune diseases, for instance lupus-like syndrome, Hashimoto′s thyroiditis, and autoimmune hepatitis.

Features and Benefits

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.
