MultiCyt™ QBeads™ by Sartorius Group

Proteins secreted by cells are involved in cell signaling and signal transduction. Aberrant production and/or dysfunctional signaling is implicated in virtually all diseases. The detection and quantification of secreted proteins provides key information for researchers in therapeutic areas ranging from cancer and immunology to aging and regeneration.

MultiCyt QBeads PlexScreen is a family of reagents that use immunochemistry to capture specific secreted proteins on distinct bead types. This enables multiplexed quantitation of cytokines, adhesion molecules, enzymes and receptors. QBeads have been developed for use exclusively with the IntelliCyt instrument technology. Together they provide an integrated screening solution that is especially applicable to therapeutic areas like immunology, toxicology and oncology.


MultiCyt™ QBeads  Features:

• No-wash assays are easy - Screening with this integrated solution uniquely allows for a no-wash protocol, greatly accelerating the screening rate and productivity of your lab.
• QBeads are better together - Multiplex up to 30 analytes in a single well.
• QBeads are fast - Typical read time for a 384-well plate of QBeads is 20 minutes. Compare this to more than 60 minutes for all other commercialized bead assays.
• QBeads are economical - The typical read volume of only 1 μl allows for smaller assay volumes than any other bead-based screening method, which lends itself to the use of higher density microplates, and the flexibility to re-read wells for confirmation of unexpected results.
• QBeads kits are all custom built - Assay Builder allows you to select precisely the analytes you want to monitor.
