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.
Binds IgG only from most mammals, except rat, goat, sheep.
Protein A–Peroxidase from Staphylococcus aureus/horseradish has been used in enzyme-linked immunosorbent assay (ELISA).
Package size based on protein content.
Lyophilized powder containing sodium citrate buffer salt. Protein determined by A205.
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.
