Leukemia Inhibitory Factor (LIF) is a lymphoid factor that promotes long-term maintenance of pluripotent embryonic stem cells by suppressing spontaneous differentiation. Recombinant Human Leukemia inhibitory factor (hLIF) is produced in E. coli. It contains a single non-glycosylated polypeptide chain 181 amino acids and has a molecular mass of 20kDa. hLIF is purified by proprietary techniques using HPLC and FPLC chromatography.
Maintain at 4°C for 18 months. Freeze-thaw should be avoided as it results in loss of activity.
