|
| Product Name | Recombinant Human IL-7 Protein |
| Expression Host | CHO cells |
| QC Testing Purity | >95% as determined by SDS-PAGE and HPLC |
| Activity | A cell proliferation assay was performed with PHA-activated PBMC cells with a corresponding specific activity of >1×10⁷ IU/mg (calibrated according to the human IL-7 reference standard (NIBSC code: 90/530). |
| Endotoxin | <0.01EU per 1μg of the protein by the LAL method. |
| Molecular Mass | The recombinant human IL-7 protein predicts a molecular mass of 43.8 kD. |
| Formulation | Lyophilized from sterile PBS, pH 7.4. Normally 6 % mannitol are added as protectants before lyophilization. |
| Stability & Storage |
Lyophilized preparation can be stored at -20 ℃. 6 months at -20℃ under sterile conditions after reconstitution. 12 months at -80℃ under sterile conditions after reconstitution. Recommend to aliquot the protein into smaller quantities after reconstituting with water for injection, normal saline or PBS, and keep the diluted concentration above 100μg/mL. Avoid repeated freeze-thaw cycles. |
| Background | IL-7 is an important cytokine for the growth, survival, and differentiation of T, B, and NK cells. The heterodimer formed by IL-7 and hepatocyte growth factor (HGF) is a precursor B cell growth stimulating factor. Studies on gene knockout in mice have shown that IL-7 plays a crucial role in the survival of lymphocytes. IL-7 stimulates pluripotent stem cells to differentiate into lymphoid progenitor cells. |
