Introduction
Leukemia inhibitory factor, is a pleiotropic cytokine which is expressed by numerous cells including activated T lymphocytes, monocytes, mast cells and neuronal cells. LIF takes part in the induction of hematopoietic differentiation in normal and myeloid leukemia cells, induction of neuronal cell differentiation, regulator of mesenchymal to epithelial conversion during kidney development, and is a key player in immune tolerance at the maternal-fetal interface.
Description
LIF produced in E.Coli is a single, non-glycosylated polypeptide chain containing 415 amino acids (23-202a.a.) and having a molecular mass of 47.2kDa.
LIF is fused to a 236 amino acid His-GST tag at N-terminus & purified by proprietary chromatographic techniques.
Source
Escherichia Coli.
