xMAP® Antibody Coupling Kit


The xMAP Antibody Coupling Kit, or “AbC” kit, is a reagent kit that contains everything a researcher needs to couple an antibody to MagPlex® Microspheres. Similar to an ELISA plate, MagPlex Microspheres can be used as the substrate on which immunoassays can be performed. Unlike a traditional ELISA, however, this assay method requires much less antibody, sample, and time; with equal or better sensitivity and dynamic range.


Since each microsphere is uniquely addressable, multiple immunoassays can be performed simultaneously with the same sample, in the same well. Once your desired antibody is coupled to the surface of the bead you can begin optimizing monoplex or multiplex capture-sandwich immunoassays to suit your needs.

Experience the benefits of immunoassays on xMAP Technology, including:

  • Less sample
  • Less antibody (up to 90% less antibody in some cases*)
  • Less labor
  • Greater reproducibility
  • Equal or better sensitivity and dynamic range

Workflow Overview



  • Conveniently includes all reagents and consumables necessary to couple antibodies to MagPlex microspheres
  • Easy to use protocol

NOTE: This kit is limited to antibody coupling and is NOT intended to be a comprehensive assay development kit.

Recommended Complementary Products

  • MagPlex Low Concentration Microspheres (MC100XX-ID) are the perfect amount of beads for assay development.
  • The Luminex Magnetic Tube Separators (CN-0288-01) are ideal for executing the wash steps required in bead coupling.

NOTE: This kit is specifically designed for coupling antibodies to MagPlex microspheres. Please visit the Support Resources to section of the website to learn about coupling nucleic acids, antibodies, and other proteins to both MicroPlex and MagPlex microspheres.



Kit Contents

  • Easy to follow coupling protocol, including guidance on how to assess coupling efficiency
  • Pre-optimized reagents and buffers, including EDC*
  • All required consumables (i.e. reaction tubes and transfer pipettes)

*Note: Kit does NOT include microspheres or antibodies.

Run Times

  • Hands-on time = ~40mins
  • Total turn-around time = ~3hrs
