LIF

Leukemia Inhibitory Factor (LIF) is a lymphoid factor that promotes long-term maintenance of pluripotent embryonic stem cells by suppressing spontaneous differentiation. Recombinant Mouse Leukemia inhibitory factor (mLIF) is produced in E. coli. It contains a single non-glycosylated polypeptide chain 181 amino acids and has a molecular mass of 20kDa. mLIF is purified by proprietary techniques using HPLC and FPLC chromatography. The sample purity is better than 99% on SDS page. Its biological activity has been determined.
