IL-7 (human) (rec.) (His)

Interleukin-7; Lymphopoietin 1; LP-1

Measured by the dose dependent stimulation of the proliferation of murine 2E8 cells. The ED50 for this effect is typically 0.2ng/ml corresponding to a specific activity of 5x 106 units/mg.

Lyophilized from 0.2µm-filtered solution in PBS.

Avoid freeze/thaw cycles.Centrifuge lyophilized vial before opening and reconstitution.PBS containing at least 0.1% BSA should be used for further dilutions.

Protein. The extracellular domain of human IL-7 (aa 26-177) is fused at the C-terminus to a His-tag. Source: HEK 293 cells. Endotoxin content: <0.01EU/µg protein (LAL test; Lonza). Lyophilized from 0.2µm-filtered solution in PBS. Purity: >95% (SDS-PAGE). Interleukin-7 (IL-7), is a hematopoietic growth factor and a member of the IL-7/IL-9 family. IL-7 stimulates the proliferation of lymphoid progenitors and is secreted by stromal cells in the bone marrow and thymus. IL-7 is also important for proliferation during certain stages of B cell maturation. IL-7 and the hepatocyte growth factor (HGF) form a heterodimer that functions as a pre-pro-B cell growth-stimulating factor. It is found to be a cofactor for V(D)J rearrangement of the T cell receptor beta (TCRbeta) during early T cell development. IL-7 can be produced locally by intestinal epithelial and epithelial goblet cells and may serve as a regulatory factor for intestinal mucosal lymphocytes.
