Product Specific Information

Use: Human IL-7 exerts activity in the range of 0.1 to 10 ng/mL for most in vitro applications.

Reconstitution and Dilution: Reconstitute in distilled water to a concentration of 100 µg/mL. After reconstitution, dilute cytokine in a neutral buffer containing carrier protein such as 5-10% FBS or 1-4% high purity BSA (fatty acid free fraction V).

Lyophilized product is stable until expiration if stored desiccated below 0ºC. Cytokines diluted as indicated above should be divided into aliquots and stored at -70ºC. Recombinant proteins should be stored at concentrations >500 ng/mL to reduce loss of activity.

Target Information

Interleukin 7 (IL-7) is a hematopoietic cytokine that is constitutively produced by stromal cells from the bone marrow and thymus. IL-7 signals through the IL-7R to promote the differentiation of hematopoietic stem cells to lymphoid precursor cells, which give rise to T cells, B cells, and natural killer cells.
