1.MECHANISM OF ACTION
This substrate operates on a protease cleavage-release mechanism. The peptide moiety (Juice-WATER) is specifically recognized and cleaved by active proteases present in the juice or enzyme preparation. Upon cleavage, the para-nitroaniline (pNA) group is liberated from the peptide backbone. Free pNA absorbs light strongly at a wavelength of 405-410 nm, producing a yellow color. The rate of increase in absorbance at this wavelength is directly proportional to the protease activity in the sample, allowing for precise kinetic or endpoint analysis.
2.PRODUCT INDICATIONS
3.CLINICAL EFFICACY OF PRODUCT
Juice-WATER-pNA is a diagnostic/research reagent, not a therapeutic. Its "efficacy" lies in its role as a standardized analytical tool. It provides a reliable, quantitative method to assess proteolytic activity, which is crucial for: 1) Food Industry Quality Control: Ensuring consistent enzymatic activity in products like meat tenderizers, clarifying agents, or dietary supplements derived from plant proteases. 2) Research & Development: Facilitating the study of enzyme properties, inhibitor screening, and optimization of extraction processes for commercially valuable enzymes. 3) Standardization: Enabling the comparison of enzyme potency across different batches and sources.
