See a full picture of binding events with ease and confidence
Meet Fluidity One-M
Your toolbox to fast-track protein interaction analysis
Measure in solution
Direct measurement in solution without purification and immobilization.
Start simple
Just mix and measure, with machine learning guided assays
Break the constraints
Works for any targets and backgrounds, such as serum, plasma and cell lysate
Work faster
Get a full binding curve and KD with a simple workflow in 25 minutes
Avoid biases
With single-use consumables. No cross-contamination
Complete the picture
Binding affinity, concentration, stoichiometry and size, all at once
Explore our technology
Get to know Microfluidic Diffusional Sizing (MDS), the technology that drives our products. MDS gives one simple and direct measurement – protein molecular size. When binding occurs, changes in protein size are monitored and used to determine binding affinity and calibration-free concentration or binding stoichiometry.
