General description

Protein G conjugated to alkaline phosphatase. Does not react with IgA, IgE, or IgM.
Protein G, Alkaline Phosphatase Conjugate is obtained by conjugation of protein G, a cell-surface protein of Streptococcus species to alkaline phosphatase. This conjugate is used as a secondary agent in immunoassay methods to detect polyclonal goat and rabbit antibodies and monoclonal mouse IgG1, IgG2a, and IgG2b.

Application

Protein G, Alkaline Phosphatase Conjugate has been used in:
  • direct enzyme-linked immunosorbent assay (ELISA) (1:1000)(1:250)
  • indirect ELISA (1:1000)
  • immunoblot (1:5000)

Packaging

Please refer to vial label for lot-specific concentration.

Warning

Toxicity: Standard Handling (A)

Physical form

In 50 mM Tris buffer, 1 mM MgCl₂, 0.1 mM ZnCl₂, 1% BSA, 0.1% sodium azide, pH 7.6.

Analysis Note

Single band at 33.8 kDa by SDS-PAGE

Other Notes

p-Nitrophenyl phosphate, 1.0 mg/ml in 10% diethanolamine, pH 9.8, 1 mM MgCl2 at 25°C, was used as substrate to test immunoenzyme reactivity. Variables associated with assay conditions will dictate the proper working dilution.
