Product Features for Human Resistin Magnetic Luminex® Performance Assay

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 Human Resistin with up to 9 analytes of your choice 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

Performance Validation for Human Resistin Magnetic Luminex® Performance Assay

Our 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.

More Information About Magnetic Bead-based Multiplex Kits For The Luminex® Platform

Magnetic Luminex High Performance Assays are designed for use with the Luminex MAGPIX CCD Imager. Alternatively, kits can be used with the Luminex 200™ or FLEXMAP 3D, dual laser, flow-based sorting and detection platforms.

Analyte-specific antibodies are pre-coated onto color-coded microparticles. Microparticles, standards, and samples are pipetted into wells and the immobilized antibodies bind the analytes of interest. After washing away any unbound substances, a biotinylated antibody cocktail specific to the analytes of interest is added to each well. Following a wash to remove any unbound biotinylated antibody, Streptavidin-Phycoerythrin conjugate (Streptavidin-PE), which binds to the biotinylated detection antibodies, is added to each well. A final wash removes unbound Streptavidin-PE and the microparticles are resuspended in buffer and read using a Luminex analyzer. One laser is bead-specific and determines which analyte is being detected. A magnet in the analyzer captures and holds the superparaMagnetic microparticles in a monolayer. Two spectrally distinct Light Emitting Diodes (LEDs) illuminate the beads. One LED identifies the analyte that is being detected and the second LED determines the magnitude of the PE-derived signal, which is in direct proportion to the amount of analyte bound. Each well is imaged with a CCD camera. Kits can also be used with Luminex 100/200 or a FLEXMAP 3D dual laser, flow-based systems.

Background: Resistin

Resistin, also known ADSF and FIZZ3, is a secreted peptide hormone that circulates as either a noncovalent trimer, or a disulfide-linked homohexamer. Resistin is expressed by white adipocytes, splenocytes, astrocytes, and anterior pituitary epithelium. It blocks Insulin-stimulated uptake of glucose by adipocytes and promotes glucose release by hepatocytes. High circulating Insulin levels induce Resistin secretion which then antagonize Insulin action.
