| Alternative Names | Interleukin-4; IL-4; B-cell stimulatory factor 1 (BSF-1); Binetrakin;Lymphocyte stimulatory factor 1; Pitrakinra |
| Organism | Homo sapiens (Human) |
| Expression Host | Mammalian cell |
| Molecular Weight | 16.3 kDa |
| Expression Region | Full Length of Mature Protein(25-153aa ) |
| Expression Region | C-terminal 10xHis-tagged(Full Length of Mature Protein ) |
| Purity | Greater than 90% as determined by SDS-PAGE. |
| Endotoxin | Less than 1.0 EU/ug as determined by LAL method. |
| Biological Activity | The ED50 as determined by the dose-dependent stimulation of the proliferation of TF-1 cells is 1.864-4.949 ng/mL. |
| Form | Lyophilized powder |
| Buffer | The default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol if the delivery form is liquid. The lyophilization buffer is Tris/PBS-based buffer, 6% Trehalose, pH 8.0 if the delivery form is lyophilized powder. Please contact us if you have any special requirment. |
| Reconstitution | We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference. |
| Storage | Generally, the shelf life of liquid form is 6 months at -20℃/-80℃. The shelf life of lyophilized form is 12 months at -20℃/-80℃. The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. |
