For Bead-Based screening assays.

iQue® Qbeads is a family of reagents that enables capture of specific proteins on distinct bead types enabling multiplexed quantitation of cytokines, adhesion molecules, enzymes, growth factors receptors and more.
These kits have been developed and optimized for use on the iQue Screener platform to provide an integrated solution with unique benefits of fast time to results, microvolume-assays, high content, and lower cost. Qbeads kits are available in different sizes to suit your research needs.

iQue® Qbeads are available in two families:

iQue® Qbeads PlexScreen: These are complete, custom-built ready-to-run kits that contain everything you need to run your assay. Each kit contains capture beads, detection reagent, standard proteins, buffers, and a template for analysis. We offer PlexScreen kits for human, mouse and rat secreted proteins. Learn More »

iQue® Qbeads DevScreen: These are capture beads that are built to help researchers analyze their unique or proprietary proteins of interest. There are two categories of DevScreen beads, with distinct surface chemistries. Learn More »

iQue® Qbeads PlexScreen

The iQue® Qbeads PlexScreen family of reagents are custom built into complete ready-to-run kits. The kits consist of beads to capture human, mouse or rat secreted proteins, detection reagents, standard protein, buffers, and analysis templates. Each analyte has been validated in no-wash and 1-wash protocols.

Key Benefits

  • No wash protocol, just add and read for fast, easily automated workflow. See workflow diagram below.
  • Custom-built to your order; we maximize your flexibility!
  • Available for human, mouse, and rat secreted proteins including cytokines, chemokines, enzymes, and growth factors.
  • Analyze up to 30 analytes simultaneously, with no reduction in analysis speed.
  • Multiplex with other kits like the iQue® Cell Membrane Integrity Kits for richer content.

iQue® Qbeads DevScreen

The iQue® Qbeads DevScreen family are bead-based kits that provide you more flexibility to make your own bead-based multiplex assays. There are two types of DevScreen kits classified based on their surface chemistries:

iQue® Qbeads DevScreen SAv: These are streptavidin coated beads that can be used to screen with biotinylated targets. There are 5 different SAv-coated bead populations and these can be multiplexed with any of the analytes from the PlexScreen panel and with the DevScreen SH panel.

iQue® Qbeads DevScreen SH: These are beads derivatized with sulfhydryl groups. These beads offer a very flexible chemistry that can covalently bind a wide variety of molecules. There are 30 sulfhydryl beads and these can be multiplexed with iQue® Qbeads PlexScreen as well as Qbeads DevScreen SAv reagents.

Key Benefits

  • Available with streptavidin or sulfhydryl surface chemistries for flexibility in coating beads with molecules of interest.
  • Plex up to 30 for higher content; fast analysis time is not effected by plex size.
  • Multiplex with other kits including iQue® Qbeads PlexScreen kits for richer content.
