LIF (Leukemia Inhibitory Factor) is a pleiotropic member of the IL-6 family of cytokines. It functions through a heterodimeric receptor complex containing a ligand-binding subunit, LIF R alpha/CD118, and a signal transducing subunit, gp130. gp130 also serves as a subunit of the receptor complexes for Oncostatin M, Cardiotrophin-1, CNTF, IL-6, IL-11, and IL-27. LIF supports uterine implantation of the embryo, pluripotency in embryonic stem cells, and proliferation of progenitor cells. It promotes regulatory T cell and inhibits Th17 cell differentiation, and it is required by the thymic epithelium to support T cell maturation. It promotes motor neuron survival and oligodendrocyte myelination, enhances adrenal production of cortisol and aldosterone, and promotes differentiation of adipocytes and cardiac smooth muscle cells. LIF can also function as an autocrine growth factor in pancreatic cancer and can induce formation of immunosuppressive tumor-associated macrophages.

Product Features
Magnetic Luminex High Performance Assays are flexible bead-based multiplex assays. They allow up to 50 user-defined target analytes to be simultaneously profiled using cell culture supernates, serum, or plasma samples. Some panels are also validated with human milk, saliva, and/or urine samples.
- Simultaneously profile Mouse LIF with a panel of related analytes in one sample
- Magnetic format allows for easier wash steps
- Undergoes similar validation testing as Quantikine® ELISA Kits
- Precise and Specific
- Requires a small sample volume (<50 µL)
- Run your assay in just 3-5 hours
- Mass-calibrated standards for consistent results with every new lot of material
- Enough reagents for one 96-well plate
- Quick turn-around time: Kits are typically shipped within 2-3 days of ordering*
*Please allow additional time for international orders.
Performance Validation
R&D Systems Luminex High Performance Assays undergo our most extensive validation testing. All Luminex High Performance Assay Panels are validated for use with serum and plasma samples. Some High Performance Assays are additionally validated for cell culture supernatants, milk, saliva, or urine, as indicated on the individual product data sheets. Luminex High Performance Assays are tested for sensitivity (three-quarters the low standard), intra-assay precision, inter-assay precision, and to ensure assay linearity for validated sample types. Recovery values for individual samples in validated sample types are also tested. Validation data for each analyte can be found in the product datasheet.

Which Luminex Assay is Right for Me?
Assays for the Luminex platform are offered as High Performance Assays or Discovery Assays.
High Performance Assays are optimized and validated as complete panels with a focused set of analytes. You can choose from Fixed Panels, Premixed options, or Configurable User Mix formats depending on your needs.
Discovery Assays deliver maximum flexibility, enabling the creation of fully customized panels tailored to your research needs. With universal reagents validated for compatibility across all analytes in the menu, they support endless customization possibilities.
Additional Information About Luminex Assays
All R&D Systems Luminex Assays are designed for use with any Luminex instrument including MAGPIX, Luminex 200, FLEXMAP 3D, and the INTELLIFLEX.
Luminex assays use color-coded, magnetic microparticles coated with analyte-specific antibodies to enable multiplex quantitation. During the assay, standards and samples are added to the wells, where target analytes bind to the capture antibodies. A biotinylated detection antibody cocktail is then introduced, followed by a Streptavidin-PE conjugate that generates a fluorescent signal proportional to the amount of analyte present.
Each microparticle is identified by a unique signature and the signal intensity is measured using a Luminex instrument. These assays are designed to deliver reliable and reproducible results with validated antibody pairs and optimized protocols. They are well suited for applications that require sensitivity, accuracy, and confidence in your data while enabling efficient multiplexing to measure multiple targets simultaneously.
