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. Mouse LIF is a 22 kDa protein containing 203 amino acid residues. View All» Key Applications:

  View All» Application Notes: RECOMMENDED QC PROTOCOL M1 Bioassay 1. The M1 bioassay is performed using in vitro semi-solid agar cultures, which contain approximately 100 cells in 1 mL volumes of DME containing 20 % FCS in 0.3% agar. 2. Add 100 μL of sample or mLIF (10(E4) units/mL in 5% FCS in isotonic saline) in two-fold serial dilutions in duplicate to 35 mm petri dishes. 3. Add 100 μL of 5% FCS in isotonic saline to two control slides. 4. Incubate at 37°C in fully humidified atmosphere of 10% CO2 in air for 7 days. 5. Score the number of colonies that show differentiation (note: 50 units is defined as the amount of activity which results in 50% of the colonies being differentiated).

    View All» Entrez Gene Summary: Leukaemia 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. View All» UniProt Summary: FUNCTION: SwissProt: P09056.1 # LIF has the capacity to induce terminal differentiation in leukemic cells. Its activities include the induction of hematopoietic differentiation in normal and myeloid leukemia cells, the induction of neuronal cell differentiation, and the stimulation of acute-phase protein synthesis in hepatocytes.SIZE: 203 amino acids; 22,287 Da SUBCELLULAR LOCATION: Secreted.SIMILARITY: SwissProt: P09056.1 ## Belongs to the LIF/OSM family. View All» Species: Mouse View All» Brand Family: Chemicon View All» Source: mLIF 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. View All» Presentation: Liquid in PBS, pH 7.4 and 0.02% Tween 20. No preservativies added. View All» Storage Conditions: Maintain at 2-8°C for 6 - 12 months. Further dilutions should be made into buffer or medium to which protein (e.g., 1% BSA) or Tween 20 has been added. Manufactured by CHEMICON International, Inc.
