Key Properties
−| Expression System | Human Cells |
|---|---|
| Biological Origin | Human |
| Biological Activity | BLI: Loaded Anti-Human SIRPA mAb-Fc(Cat#orb2993142) on Protein A Biosensor, can bind Human SIRPA-His(Cat#orb2995109) with an affinity constant of 10.1 nM as determined in BLI assay. |
| Tag | C-6His |
| Molecular Weight | Predicted: 38.31 KDa. Observed: 45-65 KDa, reducing conditions |
| Expression Region | Glu31-Arg370 |
| Purity | SDS-PAGE: Greater than 95% as determined by reducing SDS-PAGE. |
| Endotoxins | < 1 EU/µg as determined by LAL test. |
| Conjugation | Unconjugated |
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 from a 0.2 μm filtered solution of PBS, 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. |
