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.
QBeads are available in two families:
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 »
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 »

The 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.

QBeads PlexScreen is a family of reagents that uses immunochemistry to capture specific secreted proteins on distinct bead types. We offer beads for human, mouse and rat secreted proteins. Below is a list of analytes that can be screened.
|Receptor||Adhesion Molecule||Growth Factor||Enzyme|
|CD121a (IL-1 RI)||CD54|
|CD121b (IL-1 RII)||CD62E|
|Basic FGF||Granzyme B|
|CCL2 (MCP-1)||TNF (TNFα)||IL-1α||IL-12/IL-23 (p40)|
|Growth Factor||Adhesion Molecules|
|CSF2 (GM-CSF)||CD62E (E-Selectin)|
|CSF3 (G-CSF)||CD62L (L-Selectin)|
The 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:
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.
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 QBeads PlexScreen as well as QBeads DevScreen SAv reagents.
