Notes

Lot Specific Information:
Given endotoxin and ED50 values are acceptance criteria standards. For lot specific values, please contact technical support.

Detailed Reconstitution:
Centrifuge vial before opening. Suspend the product by gently pipetting the recommended solution down the sides of the vial. DO NOT VORTEX. Allow several minutes for complete reconstitution. For prolonged storage, dilute to working aliquots in a 0.1% BSA solution, store at -80C and avoid repeat freeze thaws.

Expiration Date:
12 months from date of receipt when stored at -20C to-80C as supplied. 1 month when stored at 4C after reconstituting as directed. 3 months when stored at -20C to -80C after reconstituting as directed.

Background

Interleukin-7 (IL-7, previously known as lymphopoietin-1 and pre-B-cell growth factor) is a hematopoietic growth factor that stimulates early B and T cells. It can also co-stimulate the proliferation of mature T cells with other factors such as ConA (concanavalin A) and IL-2. IL-7 can induce the formation of lymphokine-activated killer (LAK) cells, it also plays a role in the development of cytotoxic T lymphocytes (CTL). IL-7 can stimulate the production of pro-inflammatory cytokines and enhance the tumoricidal activity of monocytes/macrophages. It is produced by thymic stromal cells, spleen cells and keratinocytes. Human and murine IL-7 show cross-species reactivity.
