Description générale

C1QA (complement component 1, q subcomponent, A chain) is a versatile recognition protein with a molecular mass of 460kDa. It is synthesized by monocyte/macrophage lineage, microglia cells. Crystal structure studies have suggested a compact spherical heterotrimeric assembly held by the non-polar interactions, with a Ca2+ ion bound at the top. The bouquet type is composed of six heterotrimeric collagen-like triple helices. Its N-terminal end forms a “stalk” whereas C-terminal heterotrimeric globular domain forms individual “stems”.

Application

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.

Actions biochimiques/physiologiques

C1QA (complement component 1, q subcomponent, A chain) is involved in the activation of the classical complement pathway by binding to the immune and non-immune ligands. C1 subunit of C1Q is associated with innate immunity i.e. activation of the complement classical pathway. Deficiency of C1q leads to the lupus erythematosus and glomerulonephritis.

Caractéristiques et avantages

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.

The molecular size of C1q-binding immunoglobulin (Ig) G complexes in systemic lupus erythematosus (SLE) sera was studied by gel filtration using C1q solid-phase radioimmunoassay (C1q SPRIA). All 15 SLE sera tested contained predominantly small-sized IgG complexes, cofractionating with monomeric IgG.
