Protocol summary
- Prepare BChE standards, dye working solution and test samples
- Add BChE standards or test samples (100 uL)
- Add BChE dye working solution (100 uL)
- Incubate at room temperature for 10-30 minutes
- Monitor fluorescence intensity at Ex/Em=490/525 nm
Important notes
Thaw all the kit components at room temperature before starting the experiment.
PREPARATION OF STOCK SOLUTION
- Thiolite™ Green stock solution (200X):
Add 50 uL of DMSO (Component E) into the vial of Thiolite™ Green (Component A) to make 200X Thiolite™ Green stock solution.
- Butyrylthiocholine (BTC) stock solution (100X):
Add 120 uL of ddH2O into the vial of BTC (Component C) to make 100X BTC stock solution.
- Butyrylcholinesterase (BChE) Standard solution (5 U/mL):
Add 50 uL of ddH2O with 0.1% BSA into the vial of BChE Standard (Component D) to make 5 U/mL BChE standard solution.
PREPARATION OF STANDARD SOLUTION
For convenience, use the Serial Dilution Planner: https://www.aatbio.com/tools/serial-dilution/11407
Add 20 uL of 5 U/mL BChE standard solution to 980 uL of Assay Buffer (Component B) to generate 100 mU/mL BChE standard solution (BS1). Then take 100 mU/mL BChE standard solution (BS1) and perform 1:3 serial dilutions in Assay Buffer(Component B) to get serially diluted BChE standards (BS2 - BS7). Note: Diluted BChE standard solution is unstable and should be used within 4 hours.
PREPARATION OF WORKING SOLUTION
BChE dye working solution:
Add 50 uL of 200X Thiolite™ Green stock solution and 100 uL of 100X BTC stock solution into 10 mL of Assay Buffer (Component B) to make a total volume of 10.1 mL BChE dye working solution. Note: Keep it from light.

Test Sample |
- Prepare BChE standards (BS), blank controls (BL), and test samples (TS) according to the layout provided in Tables 1 and 2. For a 384-well plate, use 25 uL of reagent per well instead of 100 uL. Note: Treat cells or tissue samples as desired.
- Add 100 uL of BChE dye working solution to each well of BChE standard, blank control, and test samples to make the total assay volume 200 uL/well. For a 384-well plate, add 25 uL of BChE working solution into each well instead, for a total volume of 50 uL/well.
- Incubate the reaction for 10 to 30 minutes at room temperature, protected from light.
- Monitor the fluorescence increase with an fluorescence microplate reader at Ex/Em=490/525 nm.
