Activity Data
(Figure. Cell proliferation of TF-1 cells after stimulated with LIF.Leukemia Inhibitory Factor (LIF), is an interleukin 6 class cytokine that affects cell growth by inhibiting differentiation. Other properties attributed to the cytokine include: the growth promotion and cell differentiation of different types of target cells, influence on bone metabolism, cachexia, neural development, embryogenesis and inflammation. p53 regulated LIF has been shown to facilitate implantation in the mouse model and possibly in humans. To test the effect of LIF on cell proliferation, TF-1 cells were seeded into triplicate wells of 96-well plates at a density of 5,000 cells/well with 1% serum standard 1640 including various concentrations of recombinant human LIF. After incubated for 72h, cells were observed by inverted microscope and cell proliferation was measured by Cell Counting Kit-8 (CCK-8). Briefly, 10uL of CCK-8 solution was added to each well of the plate, then the absorbance at 450nm was measured using a microplate reader after incubating the plate for 1-4 hours at 37 degree C. Proliferation of TF-1 cells after incubation with LIF for 72h observed by inverted microscope was shown in Figure 1. Cell viability was assessed by CCK-8 (Cell Counting Kit-8 ) assay after incubation with recombinant LIF for 72h. The result was shown in Figure 2. It was obvious that LIF significantly increased cell viability of TF-1 cells.(A) TF-1 cells cultured in 1640, stimulated with 0.5ng/mL LIF for 72h; (B) Unstimulated TF-1 cells cultured in 1640 for 72h.)

NCBI and Uniprot Product Information
Accurate Molecular Weight: 26kDa
NCBI Description
The protein encoded by this gene is a pleiotropic cytokine with roles in several different systems. It is involved 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 may also have a role in immune tolerance at the maternal-fetal interface. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Mar 2012]
Uniprot Description

Product Notes
The LIF lif (Catalog #AAA2097262) is an Active Protein produced from E Coli and is intended for research purposes only. The product is available for immediate purchase. The Active Leukemia Inhibitory Factor (LIF) reacts with Human and may cross-react with other species as described in the data sheet. AAA Biotech's Leukemia Inhibitory Factor (LIF) can be used in a range of immunoassay formats including, but not limited to, Cell culture, Activity Assays. Researchers should empirically determine the suitability of the LIF lif for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "Leukemia Inhibitory Factor (LIF), Active Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
