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.[1] Peroxidase from Streptococcus sp. is used to maintain the H2O2 homeostasis in cells. It aids the regulation of ABC Mn2+-permease complex (psaBCA) genes.[2]

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.[3][4]

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.

Mutations in the ryanodine receptor 1 (RYR1) gene are associated with several human congenital myopathies, including the dominantly inherited central core disease and exercise-induced rhabdomyolysis, and the more severe recessive phenotypes, including multiminicore disease, centronuclear myopathy, and congenital fiber type

Protocols

Reinheitszahl (RZ) is the ratio of absorbance due to hemin (A403, Soret region) to absorbance due to protein (A275).

Questions

  1. After diluting this, how long does it keep in a fridge? (2-8 degrees Celsius)

    1 answer
    1. The solution should be stable for about one week when stored at 2-8°C. For long-term storage, the stock solution should be frozen in aliquots at -20°C.
