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.

Win the race to insights
Accelerate protein interaction analysis across a wide range of research areas

Membrane protein characterization & quantification

Serum antibody concentration
& affinity

Monoclonal therapeutic antibody characterization

Affinity & stoichiometry of amyloid species

Quality control of reagents & protein activity
