Description   Human Leukemia Inhibitory Factor (LIF) is member of the IL-6 family and is made by a variety of tissues. Human LIF signals through gp130 to activiate STAT3 in human ESCs . In mouse ESCs, LIF promotes self-renewal and pluripotentcy, but in human cells there is no indication that LIF has the same function. Instead, FGF-basic (FGF-2) and Activin A are used to promote self-renewal and pluripotent potential. Human LIF is produced in E. coli. Recombinant human LIF is a non-glycosylated protein, containing 181 amino acids, with a molecular weight of 19.9 kDa.
Molecular Weight   19.9 kDa
Purity   Purity > 95% as determined by RP-HPLC and reducing and non-reducing SDS-PAGE. Protein Content determined by UV spectroscopy at 280 nm and analysis by RP-HPLC calibrated against a known standard. Quantitation on SDS-PAGE against a known standard.
Storage   Store at -20°C. Product is guaranteed one year from the date of shipment. Following reconstitution, store at -20°C. We recommend to add a carrier protein (0.1% HSA or BSA) for long term storage.
