Find Out More About the FemtoQuest™ System
SMC® technology is a high sensitivity platform that can detect analytes down to the fg/mL level and is an ideal tool for scientists looking for downregulation of biomarkers or scientists who need to use a surrogate matrix or biomarker when the ideal target is difficult to obtain. The versatile technology spans several application areas including neuroscience, cancer research, cardiovascular disease research, immunology, and inflammation. With the FemtoQuest™ instrument, we have expanded the utility of SMC® technology by introducing 2-plex capability while broadening our offering of highly verified kits. This next generation platform offers significant advancements such as improved signal-to-noise ratio, more robust electronics, faster startup, automation friendly design, and compatibility with our highly qualified RFID tagged SMC® read plate. Control your biomarker quest by monitoring small changes in protein concentrations to accurately measure biomarkers associated with disease progression for research purposes.
Watch our informative webinar to learn more about the capabilities and data that can be generated with the FemtoQuest™ platform using SMC® technology.
How Does it Work?
The FemtoQuest™ system is a fluidics-free, image-based instrument that digitally counts fluor-conjugated molecules after excitation by a laser. Using patented algorithms for scanning and collecting signal from a well in a customized read plate, light is converted and amplified by proprietary avalanche photodiodes. The number of photons is counted within the sample over discrete time intervals. A response threshold is then calculated as events above background noise and the signal then digitized as discrete single molecule events per sample/well.
What Are the Benefits Over Other High Sensitivity Technologies?
The FemtoQuest™ system is a non-fluidic instrument which does not require expensive startup and shutdown service visits, resulting in low overall maintenance costs. Because scanning occurs beneath the plate, samples are not removed during the read process, offering recoverable runs and plate re-reading capabilities. Proprietary algorithms and data acquisition allow for optimization of each channel and an improvement in limit of detection and CVs, in addition to improvements in sensitivity. Our kits are lot-matched against a sample library, offering lot-to-lot consistency and reliable performance across studies. We also offer the option of bead-based or plate-based assay kits that include all reagents and customized read-plates; the platform also provides flexibility for self-developed assays. This offering, accompanied by our expanding menu of commercial assays and our Custom Assay Development and Innovation (CADI) services, allows you to meet all your biomarker needs.
FemtoQuest™ System Versus the SMCxPRO® Instrument Comparison
The SMC® technology has utilized the SMCxPRO® instrument since 2017 and prior to that, the proven, reliable Erenna® instrument. The FemtoQuest™ system expands and enhances the portfolio as a compact, affordable, and flexible instrument providing both dual-plex and single analyte detection at femtogram/mL levels. The sensitivity improvement positions the FemtoQuest™ system as a next generation platform to advance research.

One-Year Warranty
FemtoQuest™ systems are sold with a one-year manufacturer warranty that covers manufacturing defects within the first year of installation. Qualified field service engineers will install the FemtoQuest™ system and field application scientists will demonstrate how to maintain the instrument as part of customer training.
Contracts for service assume continuous warranty or service contract coverage. If coverage lapses and is later re-established, the instrument must first be restored to factory specifications and may result in additional costs.
Instrument Technical Support
In addition to onsite service support, our worldwide technical support team can assist you by email or telephone. Their wide range of technical expertise enables them to address questions on both hardware and software. If your concern cannot be resolved by our technical support team, we will schedule an onsite visit from a trained service engineer or application specialist.
