Biochemistry Solution

The company promotes a range of assay kits designed for the specific measurement of active protease biomarkers of disease. Our easy-to-use tests incorporate patented “ProteaseTags®”; smart molecules which trap an active protease within a complex biological sample and enable a visual readout of its presence.

Pharmaceutical Research

The company has registered a CE Mark for activity-based immunoassays targeting Neutrophil Elastase (NE) and Proteinase 3, as biomarkers of lung infection and inflammation in chronic respiratory diseases such as COPD, cystic fibrosis and bronchiectasis.

Medical Laboratory Technician

Unregulated protease activity (which occurs when the normal control of their action is lost) can be a trigger of many important human diseases thereby making active proteases important.

High-End Latest Technology

Typical antibody-based systems e.g. ELISA (Enzyme-linked ImmunoSorbent Assay) will only detect total protein with no indication of the fraction associated with the active form of the enzyme.

why choose us

We Are The Trusted Scientist Experts

Environmental Testing

Our experienced team can provide a number of services for both academic and pharmaceutical company researchers, and are able to offer sample analysis at our purpose-built laboratory for a range of proteases and other inflammatory biomarkers.

Medical Research

Standard methods of detection and quantification of active proteases are based on the hydrolysis of chromogenic or fluorogenic peptide substrates. Biological samples contain multiple activities with the potential to hydrolyse these substrates and are not sufficiently selective for biomarker studies.

Vaccines Research

ProAxsis has developed a range of unique molecules, known as ProteaseTags®, which have the capacity to rapidly and selectively bind active proteases, including those which are biomarkers of diagnostic and prognostic value.
