LIF has a number of other activities including cholinergic neuron differentiation, control of stem cell pluripotency, bone and fat metabolism, mitogenesis of certain factor dependent cell lines and promotion of megakaryocyte production in vivo. Human and murine mature LIF exhibit a 78% sequence identity at the amino acid level. Human LIF is equally active on human and mouse cells. Murine LIF is approximately 1000 fold less active on human cells than human LIF.\u003c\/p\u003e\n\n\u003cp\u003eAlternate Names: Leukemia Inhibitory Factor; LIF; Differentiation-Stimulating Factor; D Factor; Melanoma-Derived LPL Inhibitor; MLPLI; Emfilermin; LIF; HILDA\u003c\/p\u003e\n\n\u003cp\u003eDescription: Recombinant Human Leukemia Inhibitory Factor is produced by our E.coli expression system and the target gene encoding Ser23-Phe202 is expressed.\u003c\/p\u003e\n\n\u003cp\u003eAccession: P15018\u003c\/p\u003e\n\n\u003cp\u003eMolecular Weight: 19.7 KDa\u003c\/p\u003e\n\n\u003cp\u003eApparent Molecular Weight: 18 KDa, reducing conditions\u003c\/p\u003e\n\n\u003cp\u003eStorage Condition: Lyophilized protein should be stored at \u0026lt; -20°C, though stable at room temperature for 3 weeks.
