Description
Recombinant Human LIF is a 19.7 kDa protein containing 180 amino acids residues, including three disulfide bonds. Additional product information and specifications are provided on the Certificate of Analysis. All PeproGMP® products are manufactured using animal-derived component free materials. Product Description/Intended Use: PeproTech GMP recombinant proteins are manufactured for use as ancillary materials by applying applicable principles of GMP and quality control requirements from USP (United States Pharmacopeia) Chapter 1043 Ancillary Materials for Cell, Gene, and Tissue-Engineered Products. Product use statement: For research use or further manufacturing. Not for diagnostic use or direct administration into humans or animals.
Leukemia inhibitory factor (LIF) is a 20 kDa protein that belongs to the IL-6 receptor family. It binds to a heterodimeric membrane receptor made up of a LIF-specific subunit, gp190 or LIFR, and the subunit gp130, which is shared with the other members of the IL-6 family. LIF expression has been observed in various tissues including thymus, lung, and neuronal tissue. LIF can be up-regulated by pro-inflammatory cytokines such as TNFα and IL-17, and elevated levels of LIF have been found in cases of rheumatoid arthritis, neural injury, systemic inflammation, and tuberculosis. LIF displays diverse biological effects, but is best known for its ability to inhibit the differentiation of embryonic stem cells in mice and contribute to stem cell self-renewal.Human and mouse LIF share 79% sequence homology and exhibit cross-species activity. However, LIF inhibition of stem cell differentiation appears to be mouse-specific.Specifications
