| Description | Purity >95% by SDS-PAGE, MW: 19.7 kDa (SDS-PAGE). Leukemia Inhibitory Factor (LIF) is a pleiotropic cytokine belonging to the long four-helix bundle cytokine superfamily. LIF shares tertiary structure with several other cytokines, including Interleukin-6 (IL-6), Oncostatin M, ciliary neurotropic factor, and cardiotrophin-1, and their functions in vivo are also redundant to some extent. LIF can bind to the common receptor of IL-6 subfamily, gp130, and then recruit its own receptor LIF Receptor to form a ternary complex. The basal expression of LIF in vivo is low; and its expression is induced by pro-inflammatory factors, including lipopolysaccharide, IL-1, and IL-17, and inhibited by anti-inflammatory agents, including IL-4 and IL-13. The functions of LIF include proliferation of primordial germ cells, regulation in blastocyst implantation and early pregnancy, and maintenance of pluripotent embryonic stem cells. Recombinant human Leukemia Inhibitory Factor (rhLIF) produced in E. coli is a single non-glycosylated polypeptide chain containing 180 amino acids. A fully biologically active molecule, rhLIF has a molecular mass of 19.7 kDa analyzed by reducing SDS-PAGE and is obtained by chromatographic techniques. |
