Preparation and Storage
The lyophilized LIF, though stable at room temperature, is best stored desiccated below 0 degree C. Reconstituted LIF should be stored in working aliquots at -20 degree C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Related Product Information for LIF active protein
Leukemia Inhibitory Factor also called LIF is a lymphoid factor that promotes long-term maintenance of embryonic stem cells by suppressing spontaneous differentiation. Leukemia Inhibitory Factor has several functions such as cholinergic neuron differentiation, control of stem cell pluripotency, bone & fat metabolism, mitogenesis of factor dependent cell lines & promotion of megakaryocyte production in vivo. Human and mouse LIF exhibit a 78% identity in its amino acid sequence. Human LIF is as active on human cells as is it is on mouse cells, though mouse LIF is about 1000 fold less active on human cells, than human LIF. Recombinant mouse LIF produced in E. coli is a single, non-glycosylated, polypeptide chain containing 180 amino acids and having a molecular mass of 19.86 kDa.

Product Notes
The LIF lif (Catalog #AAA79172) is an Active Protein produced from E Coli and is intended for research purposes only. The product is available for immediate purchase. The Mouse LIF reacts with Mouse and may cross-react with other species as described in the data sheet. The amino acid sequence is listed below: N-Terminal Sequence: SPLPIT. It is sometimes possible for the material contained within the vial of "LIF, Active Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
