Endotoxin Level:< 0.10 EU per 1 μg of the protein by the LAL method. Predicted Molecular Mass:17 kDa Activity:Measured in a cell proliferation assay using PHA-activated human peripheral blood lymphocytes (PBL). Yokota, T. et al. (1986) Proc. Natl. Acad. Sci. USA 83:5894. The ED₅₀ for this effect is typically 0.2-0.5 ng/mL. Formulation:Lyophilized from a 0.2 µm filtered solution in PBS.See Certificate of Analysis for details. Molecule Information: IL-7 Long Name: Interleukin 7 Aliases: Lymphopoietin-1; PBGF Entrez Gene IDs: 3574 (Human); 16196 (Mouse); 25647 (Rat) Background: IL-7 Interleukin 7 (IL-7), previously known as pre-B-cell growth factor and lymphopoietin-1, is expressed by adherent stromal cells from various tissues. Mouse IL-7 has approximately 65% amino acid sequence identity with human IL-7 and both proteins exhibit cross-species activity.
