***PDQ Protease Assay, 48 Vials 10239-Protein Assays This Certified Reference Material atThe PDQ Protease Assay is a unique colorimetric assay used to detect protease activity in aqueous samples. The proprietary substrate responds to a wide range of proteases including serine, metallo, aspartate and cysteine proteases such as collagenase, proteinase K, papain, pepsin, bromelin, ficin, trypsin and chymotrypsin. PDQ can be used with just a few simple steps to measure protease activity and requires no centrifugation. The substrate is a cross
