Ella™

Ella is your immunoassay problem-solver. Everything is pre-loaded onto the Ella cartridge. Simply add sample and buffers, load the cartridge into the instrument, and walk away. Then watch Ella give you fully analyzed answers in less than 90 minutes. 

Ella assays powered by R&D Systems are available in a variety of flexible cartridge formats. From single analyte assays to custom panels, there’s an Ella cartridge that meets your needs. Choose from a menu of more than 200 fully validated assays.

Discover how the high-precision Ella platform completely changes the cost-benefit dynamics of traditional ELISAs. Ella's hands-free automated workflow reduces user error while lowering your cost per data point. Fast onboarding with fewer mistakes helps maximize the return on your immunoassay investment.

• Reduce manual steps by up to 80%.
• Save time and maximize data with preloaded standard curves.
• Get validated assay data in less than 90 minutes.

“Simple Plex assays on Ella gave us speed and efficiency so we could complete our assays quickly, and the high quality of the data meant that we could easily see differences between disease state samples and controls. Plus, sample preparation was so simple it reduced chances of errors significantly.” 

— Paulomi Aldo, Research Associate and Reproductive Sciences Core Manager, Yale University

• Less than 7% variability across assay lots.
• Reduce human error and variability with hand-free automation.
• Get consistent, reproducible answers across multiple users and sites. 

“A major advantage of Ella is that it’s very easy to use with virtually no maintenance, and it’s really fast. Simply dilute your sample and you’re ready to go—without the need for manual preparations that can take time and add user variability.” 

— Dr. Jesús F Bermejo-Martín, Principal Investigator, Hospital Universitario Río Hortega de Valladolid

• Generate triplicate data with only 25 µL of sample volume.
• Eliminate cross-reactivity by detecting each analyte in separate parallel channels.
• Extensive validation using FDA guidelines.  

"Ella allows for reproducible sample data with minimal sample input. The lower volume usage allows for the expansion of research into novel areas of angiogenesis and inflammation as they pertain to many forms of cancer."

— Andrew Nixon, Ph.D., M.B.A., Associate Professor, Medicine & Director, Duke University

Generate the data you need quickly and efficiently with customizable assay panels to interrogate multiple targets in one cartridge.
