Active Recombinant Human LIF protein(Met1-Phe202)

• Cat.No.: LIF-0330H
• Product Overview: Recombinant Human LIF (P15018-1) (Met1-Phe202) was expressed in HEK293.

Specification

• Source: HEK293
• Species: Human
• Tag: N/A
• Protein length: Met1-Phe202
• Form: Lyophilized from sterile PBS, pH 7.4. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
• Bio-activity: Measured by its ability to inhibit the proliferation of M1 mouse myeloid leukemia cells. The ED50 for this effect is typically 0.2-0.8 ng/mL.
• Molecular Mass: The recombinant human LIF comprises 180 amino acids and has a predicted molecular mass of 19.7 kDa. The apparent molecular mass of the protein is approximately 35.4 kDa in SDS-PAGE under reducing conditions due to glycosylation.
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method
• Purity: > 95 % as determined by SDS-PAGE
• Storage: Samples are stable for up to twelve months from date of receipt at -20°C to -80°C. Store it under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.
