Biological Activity
The ED50 is <0.5 ng/mL as measured by murine 2E8 cells, corresponding to a specific activity of >2.0 × 106 units/mg.

Appearance
Lyophilized powder.

Formulation
Lyophilized after extensive dialysis against PBS, pH 7.4.

Endotoxin Level
<1 EU/μg, determined by LAL method.

Reconstitution
Reconstitute the lyophilized recombinant Human Interleukin-7 (rHuIL-7) to 0.1-1.0 mg/mL using sterile distilled water or aqueous buffer containing 0.1 % BSA.

Storage & Stability
Lyophilized recombinant Human Interleukin-7 (rHuIL-7) is stored at -20°C. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer. It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Shipping
Room temperature in continental US; may vary elsewhere.

Background
Recombinant Human Interleukin-7 (r-hIL-7) has a central role in T-cell development and survival and enhances immune recovery in murine models of allo-hematopoietic stem cell transplantation (allo-HSCT). Recombinant Human Interleukin-7 induces a doubling in CD4+ and CD8+ T cells. The main effect of IL-7 is an expansion of effector memory T cells. r-hIL-7 can enhance immune recovery after a T cell–depleted allo-HSCT without causing significant GVHD or other serious toxicity[1].
