Active Recombinant Human LIF protein, His-tagged

• Cat.No.: LIF-134H
• Product Overview: Recombinant Human LIF(23-202aa) fused with His tag at C-terminal was expressed in Insect cells.

Specification

• Description: LIF, as known as leukemia inhibitory factor, is a pleiotropic glycoprotein belonging to the LI6 family of cytokines. This protein is involved in growth promotion and cell differentiation of different types of target cells, influence on bone metabolism, embryogenesis and inflammation. It is produced by the adrenal cortex and likely enhances its production of cortisol and aldosterone. Also, it can function as an autocrine growth factor in some pancreatic cancers, but induced differentiation in the leukemic cell line M1.
