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.

Specificity

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.

Application

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.
