xMAP® Antibody Coupling Kit

Antibody Coupling Kit

Everything you need to couple your capture antibody of interest to MagPlex® microspheres

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.1


xMAP Antibody Coupling KitSince 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 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 cases2)
  • Less labor
  • Greater reproducibility
  • Equal or better sensitivity and dynamic range




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