Protein A is a highly stable surface receptor produced by Staphylococcus aureus, which is capable of binding the Fc portion of immunoglobulins, especially IgGs, from a large number of species (Boyle and Reis, 1987).
Each protein A molecule can bind 2 molecules of IgG, allowing the formation of a precipitate.
Applications:Suitable for use in ELISA and Western Blot.
Other applications not tested.
Recommended Dilution:Optimal dilutions to be determined by the researcher.
Storage and Stability:Store product at 4°C if to be used immediately within two weeks.
For long-term storage, aliquot to avoid repeated freezing and thawing and store at -20°C.
Aliquots are stable at -20°C for 12 months after receipt.
Dilute required amount only prior to immediate use.
Further dilutions can be made in assay buffer.
Note: Sodium azide is a potent inhibitor of peroxidase and should not be added to HRP conjugates.
For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
Note: Applications are based on unconjugated antibody.
