| Enzyme-substrate studies | |
| Receptor-ligand interaction studies | |
| Blocking and competition assays | |
| 90-95% | Production of monoclonal antibodies |
| Enzyme-substrate studies (quantitative) | |
| Receptor-ligand interaction studies (quantitative) | |
| Blocking and competition assays | |
| ELISA and RIA (quantitative) | |
| In vivo/in vitro studies | |
| >80% | Western blotting studies (non-quantitative) |
| Immunograde | Production of polyclonal antibodies |
| >65% | Determination of the titer of antibodies in standard ELISA |
