Predicted Molecular Weight
The 180 amino acid recombinant protein has a predicted molecular mass of approximately 20 kD. The protein migrates at about 20 kD in DTT-reducing conditions and about 18 kD in non-reducing condition by SDS-PAGE. The N-terminal amino acid is Ser.
Source Species
E. coli
Purification
Greater than 97% by SDS-PAGE
Usage Summary
Stock solutions can also be prepared at 50-100 µg/mL in sterile buffer (PBS, HPBS, DPBS, or EBSS) containing carrier protein such as 0.2-1% BSA or HSA.
Bio-Activity
Human LIF induces proliferation of TF-1 cells. ED50 is equal to0.03-0.12 ng/ml, corresponding to a specific activity of 8.3-33.3 x 10^6 units/mg.
Endotoxin
Less than 0.1 EU/µg protein (determined by LAL method).
Presentation
0.22 µm filtered protein solution in PBS, pH 7.4
Storage
Store unopened at 2°C to 8°C for up to 1 week, at -20°C for up to 6 months, or at -70°C for up to 1 year. Store diluted at -20°C to -70°C. Avoid freeze/thaw cycles. For maximum results, quick spin vial prior to opening.
Restrictions
For research use only. Intended for use by laboratory professionals.
