Determination of antibody affinities and concentrations directly in serum

Explore the SeroAffinity and Concentration (SAffCon) Assay from Fluidic Sciences — a simple immobilisation-free and calibration-free workflow that provides universally comparable K_D values and absolute, calibration-free antibody concentrations. The Assay leverages Microfluidic Diffusional Sizing technology, a fast and easy method for quantifying molecular interactions in solution. It takes only 2–3 hours, uses just 60 μL of serum, and most importantly, works directly for clinical samples. Discover how it brings truly quantitative insights into the immune response to infection, vaccination, inflammation, organ transplants, or new drugs.
