Key Properties
−| Expression System | E.coli |
|---|---|
| Biological Origin | Human |
| Biological Activity | ELISA: Immobilized Human IL-17A(Cat#orb2995247) at 2μg/ml (100 μl/well) can bind Anti-Human IL-17A mAb(Cat#orb2993149).The ED50 of Anti-Human IL-17A mAb(Cat#orb2993149) is 0.185 ug/ml.. BLI: Loaded Human IL-17RA-Fc(Cat#orb2994535) on Protein A Biosensor, can bind Human IL-17A(Cat#orb2995247) with an affinity constant of -3 nM as determined in BLI assay. Loaded Biotinylated Human IL-17RA-His-Avi(Cat#orb2993686) on HIS1K Biosensor, can bind Human IL-17A(Cat#orb2995247) with an affinity constant of 0.50 nM as determined in BLI assay. Loaded Biotinylated Human IL-17RA-Fc(Cat#orb2993676) on Pro A Biosensor, can bind Human IL-17A(Cat#orb2995247) with an affinity constant of 0.79 nM as determined in BLI assay.. Cell Based Assay: Measured by its ability to induce IL-6 secretion by NIH‑3T3 mouse embryonic fibroblast cells. The ED50 for this effect is 1-7 ng/ml. |

Storage & Handling
−| Storage | Lyophilized protein should be stored at ≤ -20°C, stable for one year after receipt. Reconstituted protein solution can be stored at 2-8°C for 2-7 days. Aliquots of reconstituted samples are stable at ≤ -20°C for 3 months. |
|---|---|
| Form/Appearance | Lyophilized |
| Buffer/Preservatives | 0.2 μm filtered solution of 20mM PB, 150mM NaCl, pH 7.4. |
| Reconstitution | Always centrifuge tubes before opening.Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100μg/ml. Dissolve the lyophilized protein in distilled water. Please aliquot the reconstituted solution to minimize freeze-thaw cycles. |
| Expiration Date | 6 months from date of receipt. |
