Description_x000D_ General description_x000D_ 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._x000D_ Specificity_x000D_ 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._x000D_ Application_x000D_ Protein G- Peroxidase from Streptococcus sp. has been used in indirect ELISA and immunoblotting._x000D_ Preparation Note_x000D_ 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._x000D_ Disclaimer_x000D_ 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.
