Protein A is a highly stable surface receptor produced by Staphylococcus aureus, which is capable of binding the Fc portion ofimmunoglobulins, 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 (Sjöholm, 1975).||Protein A Sepharose is prepared by covalently coupling Protein A to 6% cross-linked sepharose beads. The coupling technique is optimized to give a high binding capacity for IgG. The capacity of IgG binding could be up to 25mg of human IgG per ml of wet gel. High binding capacity (18-22mg/ml of gel); High flow rate; Low falling off of rProtein A.||Applications: |Purification of monoclonal and polyclonal antibodies. Protein A binds to most human and mouse IgG subclasses (e.g., human IgG1, IgG2, IgG4; mouse IgG1, IgG2a, IgG2b, IgG3). It also binds to total IgG from cow, guinea pig, hamster, horse, pig, and rabbit. Protein A has little affinity to chicken, goat, rat and sheep.||Protocol:|1. Wash column with ddH2O to remove air bubbles.|2. Fill column with protein A beads.|3. Wash the column with 5X volume of Binding Buffer.|4. Dilute serum sample with Binding Buffer (1:1 ratio).|5. Invert the diluted serum sample to mix well. Make sure no bubbles in the solution.|6. Pour the solution onto the column.|7. Collect the solution and repeat step 6 & 7 for 10 times.|8. Wash the column 5-10 times with the Binding Buffer.|9. Add Elution Buffer to elute IgG (0.5-1ml each time).|10. Collect the eluent using microcentrifuge tube.|11. Repeat step 9 & 10 for 10 times.|12. Assay protein concentration and combine the fractions containing sufficient amount of IgG. ||Binding buffer: 0.05M sodium borate, 0.15M sodium chloride pH 8.0 |Elution buffer: 0.1M citric acid, pH 2.75||Storage and Stability:|Slurry may be stored at 4°C.
