Overview
Regulatory Status: RUO
Shipping:
Blue Ice or room temp
Storage:
The recombinant protein is stable for at least 2 years from date of receipt at -20°C. Reconstituted protein is stable for at least 3 months when stored in working aliquots with a carrier protein at -20°C. As with any protein, exposing the recombinant protein to repeated freeze / thaw cycles is not recommended. When working with proteins care should be taken to keep recombinant protein at a cool and stable temperature.

Background:
LIF is a pleiotrophic factor produced by multiple cell types, including T cells, myelomonocytic lineages, fibroblasts, liver, heart and melanoma. LIF promotes long-term maintenance of embryonic stem cells by suppressing spontaneous differentiation. Other activities include the stimulation of acute phase protein synthesis by hepatocytes, stimulation of differentiation of cholinergic nerves, and suppression of adipogenesis by inhibiting the lipoprotein lipase in adipocytes. While human LIF is active on mouse cells and is widely used in the maintenance of murine ESC to prevent spontaneous differentiation, mouse LIF is not active on human cells due to its inability to bind to the human LIF receptor. Recombinant Murine LIF is a 19.9 kDa protein containing 180 amino acids residues, including three disulfide bonds.
Biological Activity:
Murine LIF is fully biologically active when compared to standards. The ED50 as determined by the M1 cell differentiation assay is < 0.05 ng/ml, corresponding to a specific activity of > 2 x 107 units/mg.
