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.[2] 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.[3][4] In the presence of hydrogen peroxide, the enzyme catalyzes the oxidation of luminol.[5]
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.

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).

I bought Product P8651, Protein A Peroxidase, to hide heavy and light chain in a Western blot. How does it do that?
1 answer-
P8651 will only recognize the native antibody incubated on a blot, not what's run in the gel. This should circumvent heavy and light chain detection.
