Predicted Molecular Mass:19.6 kDa SDS-PAGE:19 kDa, reducing conditions Activity:Measured in a cell proliferation assay using TF‑1 human erythroleukemic cells. Kitamura, T. et al. (1989) J. Cell Physiol. 140:323.The ED₅₀ for this effect is typically 0.02-0.12 ng/mL.Measured by its ability to induce IL-6 secretion by M1 mouse myeloid leukemia cells.The ED₅₀ for this effect is approximately 0.5 ng/mL. Molecule Information: LIF Long Name: Leukemia Inhibitory Factor Entrez Gene IDs: 3976 (Human); 16878 (Mouse) Background: LIF Based on its helical structure, LIF (Leukemia Inhibitory Factor) is considered a member of the Interleukin-6 family of cytokines. Functionally, it has been implicated in a many physiological processes including development, hematopoiesis, bone metabolism, and inflammation. Some cell types known to express LIF include activated T cells, monocytes, astrocytes, osteoblasts, keratinocytes, regenerating skeletal muscle, mast cells, and fibroblasts.
