Protease Assay Services
Proteases are targeted successfully for the treatment of HIV and Hepatitis C. Inhibitors have been approved for the treatment of hypertension (ACE inhibitors), Diabetes (DPP-IV inhibitor), and to prevent blood clots (Factor Xa inhibitors). Studies are also underway for the treatment of Alzheimer's, COVID-19, and cancer.
Our panel of protease assays provides a platform for profiling and selectivity screening of new protease inhibitors against all major classes of proteases, such as serine proteases, cysteine proteases, threonine proteases, aspartic proteases, glutamic proteases, and metalloproteases. Selective compounds can be further characterized via both biochemical and biophysical platforms, such as surface plasmon resonance for their kinetic profile and mechanism of action on a molecular level.
- Fluorescence-based activity assay
- Low and large scale screening as well as high-throughput screening options are available
- Full protease panel screening is performed on a monthly basis

Assay Details
Assay procedure for MMP1. Internally quenched fluorescent peptide substrates contain a fluorophore (5-FAM) and a quencher (QXL 520). A fluorescence signal is generated upon peptide cleavage which is quantified for determination of protease activity.
Setups: Single-dose screening in duplicates or IC50 value determination with 5 or 10 concentrations. Other screening formats are available upon request.
Controls: No inhibitor (DMSO vehicle) control and for every assay, one target-specific control compound is tested in 10-dose IC50 format.
Turnaround time: 10 business days for standard projects. Expedited scheduling and data delivery can be arranged prior to the commencement of the studies.
Report: The raw data, % enzyme activity and control compound IC50 values will be reported in Excel format for single-dose assays. For IC50 orders, raw data, IC50 values, and curve fitting will be delivered in Excel format. Assay conditions, target, and substrate information are available upon request. Requirements for this information should be noted prior to the commencement of the study.
Screening facility: This assay is performed at our screening facility in Malvern, PA, US.
Compound requirements: In brief, for a standard project, 20ul of a 10mM DMSO stock or solid material is needed. Less material is needed for large scale screening. Please refer to our FAQs for information regarding compound preparation and shipping.
On a monthly basis, Reaction Biology performs compound screening on the full protease panel.
Please see the upcoming screening dates here.
