CULTHuman hLIF is expressed in E. coli as a fusion protein with GST using the pGEX expression system, cleaved from GST moeity with thrombin and purified by HPLC chromatography.Greater than 95% by SDS-PAGE. Endotoxin level is less than 0.1 ng per mg of LIF. Tested negative in both aseptic and mycoplasmic tests.

DescriptionLeukemia Inhibitory Factor human
OverviewHuman LIF is a 19.7 kDa protein containing 181 amino acid residues. The non-glycosylated, E. coli expressed, recombinant human LIF is indistinguishable from native LIF in its biological activities in vitro. Human and murine mature LIF exhibit a 78% sequence identity at the amino acid control. Human LIF is equally active on both human and mouse cells. Murine LIF is approximately 1000 fold less active on human cells, than hLIF.
Alternate Names
  • LIF
Background InformationLeukemia Inhibitory Factor (LIF) is a lymphoid factor which promotes long-term maintenance of embryonic stem cells by suppressing spontaneous differentiation. LIF has a number of other activities including cholinergic neuron differentiation, control of stem cell pluripotency, bone and fat metabolism, mitogenesis of certain factor dependent cell lines and promotion of megakaryocyte production in vivo.

Biological Information
Concentration100 μg/mL
PurityGreater than 95% by SDS-PAGE. Endotoxin level is less than 0.1 ng per mg of LIF. Tested negative in both aseptic and mycoplasmic tests.
SourcehLIF is expressed in E. coli as a fusion protein with GST using the pGEX expression system, cleaved from GST moeity with thrombin and purified by HPLC chromatography.
Specific ActivityThe activity of human LIF is determined by the ability to induce differentiation of M1 myeloid leukemic cells. The minimum detectable concentration of human LIF in this assay is 0.5 ng/mL. The specific activity is >=1 x 10(E8) units/mg, where 50 units is defined as the amount of human LIF required to induce differentiation in 50% of the M1 colonies in 1 mL agar cultures.
Entrez Gene Number
Entrez Gene SummaryLeukaemia inhibitory factor is a cytokine that induces macrophage differentiation. Neurotransmitters and neuropeptides, well known for their role in the communication between neurons, are also capable of activating monocytes and macrophages and inducing chemotaxis in immune cells. LIF signals through different receptors and transcription factors. LIF in conjunction with BMP2 acts in synergy on primary fetal neural progenitor cells to induce astrocytes.
