General description
Native protein from Straphylococcus Aureus, conjugated to biotin. Recognizes the Fc portions of immunoglobulins of various species.
Native protein A conjugated to biotin.
Application
Solid Phase Immunoassay (1:10,000)
Packaging
Please refer to vial label for lot-specific concentration.
Warning
Toxicity: Standard Handling (A)
Physical form
In 10 mM PBS, 1% BSA, pH 7.6.
Reconstitution
Following initial thaw, aliquot and freeze (-20°C).
Analysis Note
A single band at MW 50,000 by SDS-PAGE
Other Notes
The protein A: biotin molar ratio is determined on a lot-specific basis. Binding strength is as follows: strongly reactive, guinea pig, human IgG1, IgG2, and IgG4, and rabbit; weakly reactive: bovine, human IgA, IgM, and IgE, and mouse; nonreactive: goat, horse, human IgD and IgG3, rat, and sheep. o-phenylenediamine, 1.0 mg/ml in citrate buffer, pH 4.5, 0.1% urea peroxide at 25°C, was used as substrate for testing biotin-Protein A and avidin peroxidase functionality. Variables associated with assay conditions will dictate the proper working dilution.
