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.

Lyophilized powder.


Lyophilized after extensive dialysis against PBS, pH 7.4.

Endotoxin Level

<1 EU/μg, determined by LAL method.


It is not recommended to reconstitute to a concentration less than 100 μg/mL in sterile distilled water or aqueous buffer containing 0.1% BSA.

Storage & Stability

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.


Room temperature in continental US; may vary elsewhere.


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].

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
