Fida Biosystems

Fida Biosystems (Fidabio) enables biomolecular analysis as it should be: direct, transparent, and under native, in-solution conditions. Our proprietary technology delivers absolute measurements of hydrodynamic radius, unlocking precise characterization and quantification of proteins and nanoparticles (0.5–1,000 nm Dh) — including antibodies, exosomes, liposomes, membrane proteins, and more. Fidabio’s platform provides detailed information on affinity (Kd), kinetics (kon & koff) size, concentration, stoichiometry, conformational changes, oligomeric state, immunogenicity, and multiple binding events — directly in complex biological samples such as plasma, serum, cell lysate, or fermentation media. Unlike traditional methods, Fidabio operates in solution, with no surface immobilization. This eliminates non-specific binding artifacts and removes the need for challenging assay development — ensuring true binding events are measured, not surface effects. Whether you are studying binding kinetics, aggregation, structural changes, or particle interactions, Fidabio provides the transparent, absolute data you need to make confident decisions — in research, development, or manufacturing. Fast (minutes). Sample-efficient (ul–nl volumes). Matrix-tolerant. With in-built quality control and automation. Discover the difference when measurements match biology — not the other way around.
