Recommended Sample Types: Cell culture supernates, serum, EDTA plasma, and heparin plasma
Components: Human IL-1α/IL-1F1 Magnetic Microparticles (Part 898825) is supplied as a 100X concentrated stock (0.075 mL) with preservatives.
Other Supplies Required: Magnetic Luminex® Performance Assay Human XL Discovery Base Kit (R&D Systems®, Catalog # LUXLM000).
Sensitivity: The Minimum Detectable Dose (MDD) was determined by adding two standard deviations to the mean MFI of twenty zero standard replicates and calculating the corresponding concentration.
Six assays were evaluated, and the MDD of human IL-1α ranged from 0.194-1.19 pg/mL. The mean MDD was 0.401 pg/mL.
Correlation: This assay has been correlated to the Quantikine® ELISA Kit.
Specificity: This assay recognizes natural and recombinant human IL-1α.
Bead Region: 78
Precision
|
Intra-assay Precision (precision within an assay) - Two samples of known concentration were tested twenty times on one plate to assess intra-assay precision.
Inter-assay Precision (precision between assays) - Two samples of known concentration were tested in thirty separate assays to assess precision between assays.

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.
