Human Protease, Serine 33 (PRSS33) ELISA Kit

PRSS33, also known as eosinophil serine protease or EOS, is a chymotrypsin-family serine protease most strongly expressed in eosinophils, where it contributes to innate immune defense, allergen response, and tissue remodeling. Quantification of PRSS33 protein in human specimens supports research into eosinophil-associated inflammation, asthma, allergic disease, and parasitic infection models, as well as studies of protease-antiprotease balance in mucosal and respiratory tissues.

This colorimetric ELISA from Assay Genie is configured as a microplate-based immunoassay intended for the measurement of human PRSS33. The kit is supplied with reagents and a microwell plate for processing up to 96 determinations in a single run, with standard curve and quality-control materials to support reproducible quantitation across experiments. Readouts are captured with standard microplate readers commonly available in immunology, cell biology, and biochemistry laboratories.

Sample compatibility spans human serum, heparin plasma, EDTA plasma, cell lysates, cell culture supernatants, and tissue homogenates, giving laboratories flexibility to work with clinical-style specimens and experimental models on a single workflow. Reactivity is restricted to human PRSS33, helping reduce interference from related chymotrypsin-family serine proteases when comparing recombinant expression backgrounds or species panels. Reagents are supplied for research use only and are intended for laboratory investigation of eosinophil biology and related signaling pathways rather than diagnostic application.
