Protocol summary
- Add appropriate controls, or test samples (50 µL)
- Add Renin Red™ substrate working solution (50 µL)
- Incubate for 30 - 60 min at 37 °C incubator (for end point reading)
- Monitor fluorescence intensity at Ex/Em = 540/590 nm
Important notes
Thaw all the kit components at room temperature before starting the experiment. Prepare Renin containing biological samples as desired.
PREPARATION OF STANDARD SOLUTION
For convenience, use the Serial Dilution Planner: https://www.aatbio.com/tools/serial-dilution/13530
Add 12.5 µL of 40 µg/mL Renin Standard (Component B) into 487.5 µL of Assay Buffer (Component C) to get 1000 ng/mL Renin standard solution (Ren7). Take 150 µL of 1000 ng/mL Renin standard solution to perform 1:3 serial dilutions to get serially diluted Renin standards (Ren6 - Ren1).
PREPARATION OF WORKING SOLUTION
Add 50 μL of Renin Red™ Substrate (Component A) into 5 mL of Assay Buffer (Component C) to make a total volume of 5.05 mL. Note: The Renin Red™ Substrate should be used promptly.
SAMPLE EXPERIMENTAL PROTOCOL
Table 1. Layout of Renin standards and test samples in a solid black 96-well microplate. Ren = Renin Standards (Ren1-Ren7, 1 to 1000 ng/mL); BL = Blank Control; TS = Test Samples.

Table 2. Reagent composition for each well. Note: The Renin standards are for positive control only, and should not be relied on as a quantitation standard for enzyme activity.
Well | Volume | Reagent |
Ren1 - Ren7 | 50 µL | serial dilution (1 to 1000 ng/mL) |
BL | 50 µL | Assay Buffer (Component B) |
TS | 50 µL | sample |
- Prepare Renin containing biological samples as desired.
- Prepare the Renin standards and/or Renin-containing test samples according to the layout provided in Table 1 and Table 2. For a 384-well plate, use 25 µL of reagent per well instead of 50 µL.
- Pre-incubate the plate at a desired temperature for the enzyme reaction (e.g. 25 °C or 37 °C) for 10 - 15 min, if you are screening Renin inhibitors.
- Add 50 µL (96-well) or 25 µL (384-well) of Renin Red™ substrate working solution to the sample and control wells of the assay plate.
- Incubate the reaction at 37 °C incubator for 30 to 60 minutes.
- Monitor the fluorescence intensity with a fluorescence plate reader at Ex/Em = 540/590 nm (cut off = 570 mn). Note: The selectivity of the renin substrate used in the kit has not been thoroughly tested. It may also respond to other proteases since peptide-based protease substrates generally have low selectivity. One might use a renin-specific inhibitor for its specific test, such as in the presence of a renin-specific inhibitor, hydrolysis of the substrate is only due to the non-specific protease activity. The difference between the total activity and the activity in the presence of renin specific Inhibitor gives the renin activity in the sample.
For kinetic reading: Immediately start measuring fluorescence intensity and continuously record data every 5 minutes for 30 to 60 minutes.
For end-point reading: Incubate the reaction at 37 °C for 60 minutes or longer, kept from light if possible. And then measure the fluorescence intensity.
