产品详细信息

Reconstitute the lyophilized antiserum by adding 1 mL sterile distilled water.

The antiSerum does not cross-react with any other Human plasma proteins as tested in gel-diffusion techniques. Inter-species cross-reactivity is a normal feature of antibodies to plasma proteins, since homologous proteins of different species frequently share antigenic determinants. Cross-reactivity of this antiSerum has not been tested in detail.

In immunoelectrophoresis in agarose-plates use 2 µL human plasma or equivalent against 120 µL antiserum. In double radial immunodiffusion use a rosette arrangement with 10 µL antiserum in 3 mm diameter center well and 2 µL plasma samples (neat and serially diluted) in 2 mm diameter peripheral wells.

Dilutions may be prepared by adding phosphate buffered saline (PBS, pH 7.2). Repeated thawing and freezing should be avoided. If a slight precipitation occurs upon storage, this should be removed by centrifugation. It will not affect the performance of the antiserum. Diluted antiserum should be stored at 4°C, not refrozen, and preferably used the same day.

靶标信息

Complement component 4-binding protein (C4BP) is a plasma glycoprotein that inhibits the classical pathway of complement activation, which is mediated through antibody targeting of foreign antigen. Structurally, C4BP is a disulfide linked, multimeric protein that is composed of seven alpha chains and one beta chain. C4BP functions as a cofactor for C3beta inactivator in the cleavage of C3beta, and accelerates the decay of C4betaC2alpha (C3 convertase) by acting as a cofactor in the cleavage of C4beta by factor I. Streptococcal strains that express Ig-binding cell surface molecules, which are members of the M protein family, can bind to overlapping C4beta binding sites in C4BP and therefore, interfere with the classical pathway of complement activation. Bacteria-bound C4BP may be an evolved mechanism that downregulates complement activation in the bacterial host microenvironment, thereby reducing the occurrences of bacterial opsonization and phagocytosis.
