 Recombinant Human Interleukin-7
 IL7
 Pre-B-cell growth factor (PBGF) 
 Interleukin-7 (IL7) is encoded by the IL7 gene and secreted by stromal cells in the red marrow and thymus. It binds to the IL7 receptor, a heterodimer consisting of IL7 receptor alpha and IL2 receptor gamma chains. IL7 stimulates the differentiation of hematopoietic stem cells into lymphoid progenitor cells. IL7 can also stimulate the proliferation of B-cells, T cells and NK cells (natural killer cells). Murine IL7 has approximately 61% amino acid sequence identity with human IL7, and both proteins exhibit cross-species activity. IL7 has been examined as an immunotherapy agent in many human clinical trials for various malignancies, along with its role in HIV-positive individuals.

 Storage/Handling: This lyophilized  preparation is stable at 2-8°C, but should be kept at -20°C for long term  storage. The reconstituted sample can be apportioned into working aliquots and  stored at -80 °C for up to 6 months. Avoid repeated freeze/thaw cycles. 
 Reconstitution: The sample should  be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute  in a siliconized tube using PBS that contains a 0.1% BSA to a concentration of  0.1-1.0 mg/mL. Reconstituted solutions are stable for up to one week at 2-8°C.  Stock solutions should be aliquoted and stored at -80°C. Further dilutions  should be made in appropriate buffered solutions containing BSA or serum.
