Luminex instrument accessories

Accessory equipment and reagents are available for use with assays run on Luminex systems, including sheath fluid, calibration kits and performance verification kits. We are committed to ensuring that you have all the necessary components you need to run successful Luminex RNA & protein quantitation assays on MAGPIX, LX200, FLEXMAP 3D or INTELLIFLEX Luminex systems.

The Hand-Held Magnetic Plate Washer (96-well) is designed for fast and simple removal of supernatant from samples bound to magnetic particles. The Hand-Held Magnetic Plate Washer (96-well) is an ideal tool for use with Invitrogen singleplex and multiplex biological assays based on the Luminex xMAP Technology. These assays make use of Luminex MagPlex or magnetic microspheres, and the MAGPIX, LX200, FLEXMAP 3D or INTELLIFLEX instruments. For 384-well assay formats, we recommend using an automated magnetic plate washer for consistent and efficient bead washing.

Luminex technology

Luminex instrumentation

Luminex instrumentation is comprised of four instrument platforms—INTELLIFLEX, LX200, FLEXMAP 3D and MAGPIX. These instruments are based on either the principles of quantitative fluorescent microscopy or fluorescent flow cytometry. The multiplex quantitation capability of an assay is dependent upon instrument model, and ranges from 50 analytes with use of the MAGPIX, to 500 analytes with the INTELLIFLEX and FLEXMAP 3D. Used in combination with Invitrogen QuantiGene Plex and ProcartaPlex assays, the Luminex platform delivers fast and cost-effective gene expression and immunoassay profiling analysis in both 96- and 384-well formats. This multiplex system allows for the simultaneously measurement of up to 80 different analytes for RNA or protein from a single microplate well.

The Invitrogen QuantiGene Plex and Procarta Plex assays utilize xMAP (multi-analyte profiling) technology to perform a wide range of protein- and nucleic acid-based multiplex assays. xMAP Technology uses labeled microspheres or beads, allowing for the simultaneous capture of multiple analytes from a single reaction. The beads are individually read using a Luminex xMAP instrument.


The MAGPIX system is based on the principles of fluorescence imaging utilizing Light Emitting Diodes (LEDs) and a CCD camera. The compact MAGPIX instrument is capable of simultaneously measuring and quantitating up to 50 analytes in a single microtiter well when used with magnetic micropsheres (beads). The MAGPIX instrument has been discontinued and is no longer available for purchase but MAGPIX Calibration and Performance Verification kits as well as Drive Fluid PLUS for existing instruments will continue to be available. The Invitrogen ProcartaPlex and QuantiGene Plex assays are compatible with existing MAGPIX instruments.

LX200 and FLEXMAP 3D

The LX200 and FLEXMAP 3D reader combines two lasers, fluidics, and real-time digital signal processing to distinguish up to 80 different sets of color-coded magnetic microsphere beads, each bearing a different assay. The Luminex reader is an essential tool that performs the key functions of this multiplex technology:

Procartiflex technology fluidics


The reader detects individual beads by flow cytometry. The fluidics system of the reader aligns the beads into single file as they enter a stream of sheath fluid and then enter a flow cell. Once the beads are in single file within the flow cell, each bead is individually interrogated for bead color (analyte) and assay signal strength (PE fluorescence intensity).

Reader lasers


The reader uses a 532 nm green laser ("assay" laser) is used to excite the PE dye of the assay (streptavidin-PE). The 635 nm solid state laser (red "classify" laser) is used to excite the dyes inside the beads to determine their "color" or "region" and is also used for doublet discrimination by light scatter.

Reader detectors


The reader has four detectors, one for each of the optical paths shown in the figure below. Detectors are used to measure the fluorescence of the assay, to make bead determination (1-100) and the last to discriminate between single and aggregate beads.


The Luminex xMAP INTELLIFLEX System is the newest addition to the xMAP line of instruments that combines lasers, fluidics, and real-time digital signal processing for multiplex readouts. It is available in two configurations, the INTELLIFLEX (Cat. No APX2020) and the INTELLIFLEX DR-SE (Cat. No APX2021). The key difference between these configurations is the availability of the dual reporter and side eject feature which are exclusively to the DR-SE configuration. The additional violet reporter laser and detector in the DR-SE configuration makes the INTELLIFLEX DR-SE the only Luminex xMAP instrument capable of measuring up to 2 parameters per bead region.

The Luminex xMAP INTELLIFLEX & INTELLIFLEX DR-SE feature updated fluidics, software and a reduced footprint when compared to the Luminex 200 and FLEXMAP 3D systems. With automated start up, shut down, and maintenance routines, the Luminex xMAP INTELLIFLEX systems are easy to use and maintain, providing fast read times for both 96- and 384-well plate formats. These systems are compatible with all Invitrogen ProcartaPlex multiplex immunoassays and Invitrogen QuantiGene Plex multiplex gene expression assays which are available in both 96- and 384-well plate formats for high throughput applications.
