About This Item
Form:
lyophilized powder
General description
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.
Application
Protein A–Peroxidase from Staphylococcus aureus/horseradish has been used in enzyme-linked immunosorbent assay (ELISA).
Biochem/physiol Actions
Binds IgG only from most mammals, except rat, goat, sheep.
Packaging
Package size based on protein content.
Physical form
Lyophilized powder containing sodium citrate buffer salt. Protein determined by A205.
Preparation Note
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.

The notion that postweaning multisystemic wasting syndrome (PMWS)-affected pigs develop an impaired humoral response against porcine circovirus type 2 (PCV2) has been reported in several studies. However, little information is available regarding the presence of neutralizing antibodies (NA) in PCV2-infected

The plant hormone abscisic acid (ABA) orchestrates plant adaptive responses to a variety of stresses, including drought. This signaling pathway is regulated by reversible protein phosphorylation, and genetic evidence demonstrated that several related protein phosphatases 2C (PP2Cs) are negative regulators

Influenza virus entry occurs in endosomes, where acidification triggers irreversible conformational changes of the hemagglutinin glycoprotein (HA) that are required for membrane fusion. The acid-induced HA structural rearrangements have been well documented, and several models have been proposed to relate
Protocols
This procedure is for the determination of Peroxidase enzymatic activity using Pyrogallol as the substrate.
To standardize a procedure for the assay of Peroxidase using 2,2'-Azino-bis(3-Ethylbenzthiazoline-6-Sulfonic Acid) as a substrate.
Reinheitszahl (RZ) is the ratio of absorbance due to hemin (A403, Soret region) to absorbance due to protein (A275).
