Description générale

Protein A is a cell wall constituent of Staphylococcus aureus, with a molecular weight of 56kDa. It possesses five binding domains which interact with heavy chains of immunoglobulins at the Fc or Fab fragment. In response to protein A, the complement system, interferon production, hypersensitivity reactions and cell-mediated cytotoxicity get activated. Horseradish peroxidase is a heme-containing enzyme. In the presence of hydrogen peroxide, the enzyme catalyzes the oxidation of luminol.

Spécificité

Binds IgG only from most mammals, except rat, goat, sheep.

Application

Protein A–Peroxidase from Staphylococcus aureus/horseradish has been used in enzyme-linked immunosorbent assay (ELISA).

Conditionnement

Package size based on protein content.

Forme physique

Lyophilized powder containing sodium citrate buffer salt. Protein determined by A205.

Notes préparatoires

Protein A, extracellular, coupled to Peroxidase, Type VI, by a modification of the procedure of O′Sullivan, M.J., et al., FEBS Lett., 95, 311 (1978), which favors low molecular weight conjugates.

Protocoles

To standardize a procedure for the assay of Peroxidase using 2,2'-Azino-bis(3-Ethylbenzthiazoline-6-Sulfonic Acid) as a substrate.

This procedure is for the determination of Peroxidase enzymatic activity using Pyrogallol as the substrate.
