| Source | Rat IFN-γ, amino acids Gln23-Cys156 (Accession# NM_138880) was expressed in E. Coli. |
|---|---|
| Molecular Mass | 16 kD |
| Purity | >98% |
| Formulation | Lyophilized in sterile-filtered PBS, pH 7.2, containing 1% BSA, 0.09% sodium azide, and protease inhibitors. |
| Concentration | Lot-specific (to obtain lot-specific concentration and expiration, please enter the lot number in our Certificate of Analysis online tool.) |
| Storage & Handling | Unopened vials can be stored between 2°C and 8°C until the expiration date. Prior to use, reconstitute the lyophilized powder with 0.2 mL of PBS containing a carrier protein (e.g., 1% BSA, protease free), pH7.4. Re-cap vial, vortex. Allow the reconstituted standard to sit at room temperature for 15 minutes, vortex again to mix completely. The reconstituted standard stock solution can be aliquoted into polypropylene vials and stored at -70°C for up to one month. Do not re-use diluted standards. Avoid repeated freeze/thaw cycles. |
| Application | ELISA - Quality tested |
| Recommended Usage | Each lot of this protein is quality control tested by ELISA assay. For use as an ELISA standard, a standard curve comprised of two-fold dilutions from 2000 pg/ml to 31 pg/ml is suggested. It is recommended that the reagent be titrated for optimal performance for each application. |
Unless otherwise stated, the minimum order amount is USD 1,000.
