Description
Interleukin-7 (IL-7) is required for the development and survival of T cells and plays a critical role in modulating T-cell homeostasis.IL-7 is a limiting resource under normal conditions, but it accumulates during lymphopaenia, leading to increased T cell proliferation.Human IL-7 shares approximately 60-63% aa sequence identity with mouse, rat, canine and feline IL-7, and 72-76% with equine, bovine, ovine, porcine, feline and canine IL-7. IL-7 as an immunotherapy agent has been examinedin many human clinical trials for various malignancies and during HIV infection. Furthermore, IL-7 induces the arming of effector functions and enhances the sensitivity of MAIT cells.

Reconstitution |
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20°C. Further dilutions should be made in appropriate buffered solutions. |
Shipping and Storage
The products are shipped with ice pack and can be stored at -20 ℃ for 1 year.
1 month, 2 to 8 °C under sterile conditions after reconstitution.
3 months, -20 °C under sterile conditions after reconstitution.
Recommend to aliquot the protein into smaller quantities when first used and avoid repeated freeze-thaw cycles.
Cautions
- Avoid repeated freeze-thaw cycles.
- For your safety and health, please wear lab coats and disposable gloves for operation.
