| | PROTEIN A RESIN Usage And Synthesis |
| Uses | Purification of mouse monoclonal antibodies from ascites fluid or cell culture supernatants. Protein A or Protein G Agarose affinity matrix can be used to purify antibodies from crude cell extracts and for the immunoprecipitation or co-immunoprecipitation of proteins. It has also been used for photoactivatable-ribonucleoside-enhanced cross-linking immunoprecipitation (PAR-CLIP) analysis. | | General Description | extracellular protein A is immobilized on cross-linked CNBr-activated agarose 4B | | Biological Activity | Protein A binds to Fcγ (the constant region) and Fab (antigen binding fragment) of IgG. Protein A agarose resin is commercially used for affinity based purifications. |
