Active Recombinant Human LIF protein, hFc-tagged

• Cat.No.: LIF-248H
• Product Overview: Active Recombinant Human LIF protein(P15018)(Met1-Phe202) was expressed in HEK293 with the Fc region of human IgG1 at the C-terminus.

Specification

• Species: Human
• Source: HEK293
• Tag: Fc
• Protein Length: 1-202 aa
• Form: Lyophilized from sterile PBS, pH 7.4.
• Bio-activity: 1. Measured by its ability to inhibit the proliferation of M1 mouse myeloid leukemia cells. The ED50 for this effect is typically 0.6-3 ng/ml. 2. Measured by its ability to bind human LIFR-His in a functional ELISA.
• Molecular Mass: The recombinant human LIF/Fc is a disulfide-linked homodimer. The reduced monomer comprises 421 amino acids and has a predicted molecular mass of 46.7 kDa. The apparent molecular mass of the protein is approximately 63 kDa in SDS-PAGE under reducing conditions.
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method
• Purity: > 95 % as determined by SDS-PAGE.
• Storage: Store it under sterile conditions at -20°C to -80°C upon receiving. Recommend to aliquot the protein into smaller quantities 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.
