MILLIPLEX® kits are manufactured in facilities that are ISO 9001-2015 compliant and are for research use only (RUO), and not for use in clinical or for medical diagnostic purposes. Discover how our quality differentiates our MILLIPLEX® assays from development to manufacturing.
MILLIPLEX® kits are tested for assay sensitivity, cross-reactivity, precision, and more. Table 1 describes the criteria.
Most of our MILLIPLEX® kits are customizable, often referred to as “configurable,” which means you may choose one, any number, or all of the analytes listed for your research, and you only pay for the analytes you select.
Please only mix reagents if the kit reagents are all from the same lot (lot numbers are on each bottle label inside the kit) and the reagents have been stored under the recommended conditions.
Each kit is developed and verified to optimally perform with the included reagents and according to protocol recommendations. Combining kits can risk antibody cross-reactivity, incompatible sample dilution factors, inappropriate serum matrix, buffers, or incubation periods – any of which can skew your results.
If you wish to combine analytes from different kits, check out our Custom Assays. You can rely on our expertise to help you find the best options for your research needs.
Our kits have been tested in the sample types indicated in each kit protocol. Typically, our kits are tested for use with plasma or serum samples, cell culture samples, or lysate samples.
Some of our kits have been specifically tested for urine or CSF (cerebral spinal fluid). Before trying our kits with a new sample type, please contact Technical Support for recommendations or our Custom Assays team can run verification testing on your specific sample type.

Each MILLIPLEX® multiplex kit has a base price for the kit with one analyte. Each additional analyte adds incrementally to the price. If you only wish to detect one or two analytes, two separate single analyte ELISA kits may suit your budget and research needs. However, when you interrogate multiple analytes, multiplexing becomes a real cost-saver.
If your goal is to save precious sample volume, then multiplexing is key. Most of our MILLIPLEX® kits require only 25 µL of sample, sometimes “neat” and sometimes diluted, according to each protocol. You save time and sample by running just one easy assay to quantify all your selected analytes of interest. Our kits come with all the reagents you need to complete your assay, including the assay plate and sealers. Just add water, sample, and follow the protocol.
A Luminex® instrument is required to run Luminex® technology-based immunoassays, including MILLIPLEX® assays and kits. There are several instruments currently available for use with MILLIPLEX® kits:
For more information on the differences between these instruments, visit our Luminex® Multiplexing Platforms Comparison page. These instruments may be purchased from us or other Luminex® partners. The Bio-Plex® instrument may also be used to run any Luminex® technology-based immunoassay including MILLIPLEX® assays.
