Human Th1/Th2 Magnetic Luminex Performance Assay 11-plex Fixed Panel 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 11 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

Performance Validation

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.

Precision

Intra-Assay Precision - is generated from the mean of the %CV's from 40 reportable results across two different concentrations of analytes in a single serum assay Inter-Assay Precision - is generated from the mean of the %CV's across two different concentrations of analytes across 25 different serum assays.
	n=40 (20x2 levels)	n=25
Analyte	Intra-Assay (%CV)	Inter-Assay (%CV)
GM-CSF	3.1%	10.3%
IFN-gamma	2.8%	10.4%
IL-10	3.3%	9.0%
IL-12 p70	2.3%	10.5%

Accuracy

Linearity - The data represents mean spiked or natural linearity in serum matrix samples. Samples with natural linearity are marked with an astrisk. Spike Recovery - The data represents mean percent recovery of spiked standards ranging from low, medium, and high concentration in serum matrix samples.

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.

	Human Th1/Th2 Luminex Panel Standard Curves

Background: Th1/Th2 Assay Kits

T helper cells (Th) play a vital role in the adaptive immune system by suppressing or regulating immune responses. After activation, T helper cells differentiate into T-helper (Th) 1 or Th2 effector cells. These two subsets are characterized by their distinct cytokine expression pattern and the immune function they mediate. Th1/Th2 paradigm provides rationale for developing new vaccines against infectious diseases and novel strategies for the therapy of allergic and autoimmune disorders.
Th1 and Th2 cells each produce a specialized combination of cytokines that depends on type of pathogen that the helper T cell has recognized—some cytokines are more effective than others in the process of eliminating certain invaders
