• Protein Length: Full Length of Mature Protein
• Source: Mammalian cell
• Biological Origin: Homo sapiens (Human)
• Expression Region: 23-202aa
• Endotoxins: Not test.
• Storage: The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
• Buffer/Preservatives: If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.
• Alternative names: (LIF)(Differentiation-stimulating factor)(D factor
• Note: For research use only
• Application notes: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.
• Expiration Date: 6 months from date of receipt.

(Tris-Glycine gel) Discontinuous SDS-PAGE (reduced) with 5% enrichment gel and 15% separation gel.

Measured by its binding ability in a functional ELISA. Immobilized Human LIF at 2 μg/ml can bind Human LIFR protein. The EC50 is 8.067-9.260 ng/mL.
