Learn More About Single Plex, Multianalyte, and Multiplex Assays
Single Plex assays quantify up to 16, 32, or 72 samples in triplicate. All Simple Plex cartridges deliver results in 90 minutes or less with better sensitivity and reproducibility than manual ELISAs. Single Plex assays are factory calibrated so you don't have to run a standard curve. Kits come with everything you need to run the assay including the sample diluent and wash buffers. The capture and detection antibodies as well as the fluorescent detector are already pre-loaded in the cartridge. Just load the sample, start the software, and walk away.

Multianalyte assays allow you to quantify 2, 3, or 4 target analytes in parallel. Each microfluidic channel has a unique immunoassay sandwich, consisting of high-quality capture and detection antibodies. Multianalyte Simple Plex cartridges are available in 16 and 32 sample configurations, with built-in triplicate measurements for every analyte. When you need high-quality data from your sample and high throughput, the 32x2, 32x3, and 32x4 cartridges offer flexible options that are perfect for your biomarker research.
