Applications
Our Abpromise guarantee covers the use of ab9386 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
| Application | Notes |
|---|---|
| Sandwich ELISA | sELISA: Use at an assay dependent dilution. This antibody can be used in a sandwich ELISA for the determination of human IFN-a2b. It recognizes different epitopes than monoclonal antibody 4E10 (ab9388). We recommend using this antibody as a capture antibody and ab9388 as a detection antibody. |
| Inhibition Assay | Inhib: 1/400 - 1/1000. |
| WB | WB: 1/1000 - 1/5000. At 5 µg/ml, this ab inhibits 90% of IFN-a2b antiviral activity in vitro: The bioassay was performed using L41 cell line and mouse encephalomyocarditis virus (EMCV). Interferon was pre-incubated with the ab for 2 h at RT and then added to the cell monolayer. 24h later the cells were infected with EMCV and cultured for further 24h. Antiviral activity of IFN was evaluated using crystal-violet staining. PAbs to respective interferons and an irrelevant MAb of same isotype were used as controls. |
| Indirect ELISA | I-ELISA: 1/1000 - 1/10000. |
Target
