General description

Protein G is a bacterial cell wall protein, which has high affinity for immunoglobulin G (IgG). It is isolated from group G streptococcal strains. Peroxidase from Streptococcus sp. is used to maintain the H2O2 homeostasis in cells. It aids the regulation of ABC Mn2+-permease complex (psaBCA) genes.


The product binds IgG for most mammalian species (excluding feline) and can be used in ELISA or immunohistochemical formats. Protein was determined to be at 250-350ug per 250ug vial by UV absorbance. Reactive to chicken IgG as well.


Protein G- Peroxidase from Streptococcus sp. has been used in indirect ELISA and immunoblotting.

Preparation Note

Labeled with peroxidase type VI by a modification of the procedure of O′Sullivan, M.S., et al., FEBS Lett., 95, 311 (1978) which favors low molecular weight conjugates. Conjugate is purified by gel filtration.


Unless otherwise stated in our catalog or other company documentation accompanying the product(s), our products are intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals.
