General description

CD46 (CD46 molecule, complement regulatory protein) is a membrane cofactor protein, and behave as a complement regulatory receptor for C3b and other pathogens.

Immunogen

Membrane cofactor protein precursor recombinant protein epitope signature tag (PrEST)

Application

Anti-CD46 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.
Applications in which this antibody has been used successfully, and the associated peer-reviewed papers, are given below.

Biochem/physiol Actions

CD46 (CD46 molecule, complement regulatory protein) is involved in the T-cell-mediated immunity and tolerance. In presence of IL-2, CD46 acts as a costimulatory factor and induces signals for the Tr1 (T-regulatory 1)-specific cytokine phenotype in human CD4+ T cells. These stimulated CD4+ cells multiply fast to restrict the activation of bystander T cells. It also plays a major role in human spermatozoon-oocyte interaction at the oocyte plasma membrane.

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.

The immune system must distinguish not only between self and non-self, but also between innocuous and pathological foreign antigens to prevent unnecessary or self-destructive immune responses. Unresponsiveness to harmless antigens is established through central and peripheral processes. Whereas clonal deletion
