Antibody Arrays

More Data, Less Sample!

Antibody arrays are a multiplex assay that simultaneously measures the expression of multiple proteins. They allow a much broader view of protein activity than can be obtained with single-target ELISAs and western blots. Several platforms (planar vs. bead-based) and techniques for visualizing protein expression (chemiluminescent, fluorescent, etc.) can be used depending on the sample or analyte requirements, which allows for a more comprehensive analysis of biological responses and functions and identification of key factors or disease mechanisms.

Quantibody® Multiplex ELISA

Capture 4x the data with much less sample - Process 100s of samples a day

Build a clear and accurate picture of the expression levels of multiple proteins simultaneously with Quantibody® Mulitplex ELISAs.

Combining the specificity and sensitivity of an ELISA with the high throughput of an array, Quantibody® is an array-based multiplex ELISA system for the simultaneous quantitation of multiple cytokines, growth factors, proteases, soluble receptors, and other proteins from a wide range of sample types.

With this platform, you need a mere 50 µL of sample to quantify up to 40 proteins in quadruplicate, making this array 80 times more efficient than traditional ELISA

  • More cost-effective than traditional ELISA
  • High specificity and system reproducibility
  • Suitable for diverse sample types
  • Low sample volume requirement
  • Get results same day (6-hour processing time)
  • Well-suited for high throughput assays
  • Q Analyzer software provides one-step computation

Cytometric Bead Arrays: RayPlex™

Quantitative Multiplex Bead Immunoassay

RayPlex™ Cytometric Bead Arrays enable high throughput multiplex protein detection in a wide variety of sample types with flow cytometry. By using different combinations of microbead sizes and fluorophores, multiple target proteins are analyzed simultaneously. RayPlex™ features low sample volume requirements, high specificity, and high reproducibility using a standard flow cytometer. Read more


  • Quantify up to 25 proteins with 25 µl or less sample
