Recombinant mouse LIF (Cat. No. 554002) (black circles) inhibits proliferation of M1 cells. LEAF™ purified anti-mouse LIF (clone Poly5232) (purple squares) neutralizes the cell proliferation inhibited by recombinant mouse LIF at 0.5 ng/mL on M1 cells in a dose-dependent manner, whereas the LEAF™ purified goat IgG, isotype control (gray triangles) does not have the effect. ND50 range: 0.004 – 0.028 µg/mL

    Whole cell extracts (15 µg total protein) from Raw264.7 cells spiked with the indicated amount of recombinant mouse LIF protein (Cat. No. 554008) were resolved by 4-12% Bis-Tris gel electrophoresis, transferred to a PVDF membrane, and probed with 1.0 µg/mL LEAF™ purified anti-mouse LIF (clone Poly5232) overnight at 4°C. Proteins were visualized by chemiluminescence detection using HRP-conjugated donkey anti-goat. Direct-Blot™ HRP anti-GAPDH (Cat. No. 607904) was used as a loading control at a 1:50000 dilution. Western-Ready™ ECL Substrate Premium Kit (Cat. No. 426319) was used as a detection agent. Lane M: Molecular weight marker

Leukemia inhibitory factor (LIF) is a 20 kD protein that belongs to the IL-6 receptor family. It binds to a heterodimeric receptor composed of a type I transmembrane ligand-binding subunit, the LIF-specific subunit gp190 (LIFR), and the type I transmembrane signal transducing subunit gp130, shared with the other members of the IL-6 family. It especially signals through STAT3 and JAK kinases. LIF expression has been observed in various tissues including thymus, lung, and neuronal tissues. 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. LIF can be upregulated by proinflammatory cytokines such as TNF-α and IL-17, and elevated levels of LIF have been found in cases of rheumatoid arthritis, neural injury, systemic inflammation, and tuberculosis. 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. 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.

Related FAQs

Do you guarantee that your antibodies are totally pathogen free?

BioLegend does not test for pathogens in-house aside from the GoInVivo™ product line. However, upon request, this can be tested on a custom basis with an outside, independent laboratory.

Does BioLegend test each Ultra-LEAF™ antibody by functional assay?

No, BioLegend does not test Ultra-LEAF™ antibodies by functional assays unless otherwise indicated. Due to the possible complexities and variations of uses of biofunctional antibodies in different assays and because of the large product portfolio, BioLegend does not currently perform functional assays as a routine QC for the antibodies. However, we do provide references in which the antibodies were used for functional assays and we do perform QC to verify the specificity and quality of the antibody based on our strict specification criteria.

Does BioLegend test each Ultra-LEAF™ antibody for potential pathogens?

No, BioLegend does not test for pathogens in-house unless otherwise indicated.  However, we can recommend an outside vendor to perform this testing as needed.

Have you tested this Ultra-LEAF™ antibody for in vivo or in vitro applications?

We don't test our antibodies for in vivo or in vitro applications unless otherwise indicated. Depending on the product, the TDS may describe literature supporting usage of a particular product for bioassay. It may be best to further consult the literature to find clone specific information.
