| | Enzymatic Assay for MASP-2 |
| Description: | The MASP-2 assay protocol was carried out as follows. Test compounds were serially diluted in DMSO and then 100 nL of each dilution was transferred to the assay plate(s). 10 μL of Assay Buffer was added, followed by 15 μL of Enzyme (MASP-2 (CCP1-CCP2-SP) in Assay Buffer. 15 μL of Substrate in Assay Buffer was then added and mixed to start the reactions. After 20 min at room temperature, 15 μL of a stop solution (0.1 M acetic acid) was added, mixed and the plates were read on a SpectraMax i3× Microplate Reader and exported as Excel files. Each assay plate included a “no inhibitor” (DMSO Only) control, a “no enzyme” control and a reference inhibitor control. % Activity values=100*(ave. test comp. fluorescence−ave. “no enz” fluorescence)/(ave. “DMSO only” fluorescence−ave. “no enz” fluorescence). IC50 and Ki values were very reproducible, falling well within ±2-fold. |
