Functional Assays

The Activated Protein C (APC, also known as PROC) Assay Kit is a 96-well format fluorogenic assay designed to measure the protease activity of Activated Protein C (PROC) for screening and profiling applications. <img src="{{media url="wysiwyg/Other/78827_1.png"}}" alt="" width="645" height="251" /> Illustration of the assay principle. <br />The substrate is an internally quenched fluorogenic substrate. Proteolysis releases the highly fluorescent AMC. Fluorescence intensity increases proportionally to the activity of the protease.  

The CSF1R Kinase Assay Kit is designed to measure CSF1R kinase activity for screening and profiling applications using ADP-Glo® as a detection reagent. 

The MMP26 (Matrix metalloproteinase 26) Fluorogenic Assay Kit is designed to measure MMP26 protease activity for screening and profiling applications, in a homogeneous assay with no time-consuming washing steps. 

The USP1 Inhibitor Screening Assay Kit is a 96-well format fluorogenic assay designed to measure the activity of the deubiquitinating (DUB) enzyme USP1 for screening and profiling applications. To determine the effect of an inhibitor on USP1 activity, the enzyme should be preincubated with or without the test inhibitor prior to adding the Ub-AMC substrate to the reaction. The assay was functionally validated using Ub-Aldehyde, a potent inhibitor of the DUB subfamilies Ubiquitin C-terminal Hydrolases (UCHs), Ubiquitin-Specific Proteases (USPs), Ovarian Tumor Proteases (OTU), and Machado-Josephin Domain (MJD) proteases.  Ubiquitin-AMC is a fluorogenic substrate for ubiquitin hydrolases based on the C-terminus derivatization of ubiquitin with 7-amido-4-methylcoumarin (AMC). In the conjugated form, the energy emitted from fluorochrome AMC is quenched. Upon proteolysis, AMC is no longer quenched and emits fluorescence with an λexcitation/λemission maxima of 350/460 nm. The increase in fluor

The USP5 Inhibitor Screening Assay Kit is a 96-well format fluorogenic assay designed to measure the activity of the deubiquitinating (DUB) enzyme USP5 for screening and profiling applications. To determine the effect of an inhibitor on USP5 activity, the enzyme should be preincubated with or without the test inhibitor prior to adding the Ub-AMC substrate to the reaction. The assay was functionally validated using Ub-Aldehyde, a potent inhibitor of the DUB subfamilies Ubiquitin C-terminal Hydrolases (UCHs), Ubiquitin-Specific Proteases (USPs), Ovarian Tumor Proteases (OTU), and Machado-Josephin Domain (MJD) proteases.

The 3CL Protease (T21I, S144A) (SARS-CoV-2) Assay Kit is a 96-well homogeneous fluorogenic assay designed to measure the activity of T21I, S144A mutated 3CL Protease for screening and profiling applications, with no time-consuming washing steps. 3CL inhibitor GC376 is also included as a control. <img src="{{media url="wysiwyg/coronavirus/78834_pic.png"}}" alt="" width="551" height="228" /> The 3CL Protease Substrate is an internally quenched 14-mer fluorogenic peptide (DABCYL-KTSAVLQSGFRKME-EDANS). When the donor (EDANS) and acceptor (DABCYL) fluorophores are in close proximity the energy emitted from EDANS is quenched by DABCYL (intact substrate). Upon proteolysis by 3CL, the peptide substrate is cleaved between the glutamine and serine residues to generate the highly fluorescent peptide fragment (SGFRKME-EDANS). The fluorescence intensity increases proportionally to the activity of 3CL. More information on the substrate, including MW and structure, can be found on our website (BPS Bi
