Active Recombinant Mouse Lif, His-tagged, Biotinylated

• Cat.No.: Lif-719M
• Product Overview: The recombinant mouse LIF is expressed as a 202-amino acid protein consisting of Ser24 - Phe203 region of (UniProt accession #P09056) and a C-terminal His-tag. It contains 6 potential N-linked glycosylation sites.

Specification

• Species: Mouse
• Source: Human Cells
• Tag: His
• Protein Length: 24-203 a.a.
• Form: Supplied at 0.5 mg/ml in sterile PBS pH7.4 (carrier & preservative free). The purified recombinant protein was labeled with Biotin (3-5 Biotin per molecule).
