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.

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:
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.

Clinical gene therapy trials for cardiovascular diseases have demonstrated the crucial role of efficient gene delivery and transfection technologies in achieving clinically relevant results. We hypothesized that the use of tropism-modified adenoviruses would improve transduction efficacy and to this end

CD46 (membrane cofactor protein) is a cell surface complement regulatory glycoprotein that facilitates enzymatic cleavage of complement component C3b; it is expressed by both human oocytes and acrosome-reacted spermatozoa. Murine anti-CD46 monoclonal antibody (mAb) has been reported to decrease significantly

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

The widely expressed transmembrane molecule CD46 is the complement regulatory receptor for C3b as well as the receptor for several pathogens. Beside its binding functions, CD46 is also able to transduce signals. We showed that CD46 aggregation on human T
