ProXentia owns an innovative technology called Reflective Phantom Interface (RPI). RPI instruments are intrinsically multi-analyte: this allows to study, characterize and measure many different interactions between receptor and ligand in a sample at the same time. Through RPI, you can analyze different types of molecules like DNA, RNA, proteins, protease, peptides, carbohydrates and small molecules.

Assay Development

Custom Assay Development

The RPI technology can be used effectively for the development of diagnostic assays. ProXentia develops tests based on specific needs. Both optically (cloudy and colored solutions) and biochemically (presence of interferers, non-specific signals or organic solvents) complex matrixes can be analyzed with RPI technology.


Screening Anitibody Test

ProXentia has optical, label-free biosensors based on RPI technology. These powerful instruments can be used for the development of new medications, for the selection of mono and polyclonal antibodies and for the characterization of different biomolecular interactions.

Kinetics & Affinity

Antibody Antigen Affinity

ProXentia can measure many different properties of interactions like affinity, constant of association or dissociation. This happens through a multi-analyte test in which many different receptors are immobilized on the biosensor’s surface.

Spotting Service

Microarray Service Deposition

ProXentia owns micro-deposition technologies for the realization of protein, nucleic acids and other biomolecules arrays.
