AT A GLANCE
Protocol summary
- Prepare Formaldehyde standards and/or test samples (50 µL)
- Add AldeLight™ Green working solution (50 µL)
- Incubate at RT for 20 to 60 minutes
- Monitor fluorescence increase at Ex/Em = 410/525 nm (Cutoff = 495 nm)
Important notes
Thaw all the kit components to room temperature before starting the experiment.
PREPARATION OF STOCK SOLUTION
1. AldeLight™ Green stock solution (500X):
Add 20 µL of DMSO (Component D) into the vial of AldeLight™ Green (Component A) to make 500X AldeLight™ Green stock solution.
2. Formaldehyde stadard solution (123 mM):
Add 5 µL of 37.2% of Formaldehyde Standard (Component C) into 0.5 mL of Assay Buffer (Component B) to make 123 mM Formaldehyde standard solution.
PREPARATION OF STANDARD SOLUTION
For convenience, use the Serial Dilution Planner: https://www.aatbio.com/tools/serial-dilution/10057
Add 12.2 µL of 123 mM Formaldehyde standard solution into 0.5 mL of Assay Buffer (Component B) to make 3 mM Formaldehyde standard solution. Take 3 mM Formaldehyde standard solution and perform 1:10 in Assay Buffer (Component B) to make 300 µM Formaldehyde standard (FS7). Take 300 µM Formaldehyde standard (FS7) and perform 1:3 serial dilutions to get serially diluted Formaldehyde standards (FS6-FS1) with Assay Buffer (Component B).
PREPARATION OF WORKING SOLUTION
Add 10 µL of 500X AldeLight™ Green stock solution into 5 mL of Assay Buffer (Component B) and mix well to make AldeLight™ Green working solution. Note: 5 mL of AldeLight™ Green working solution is enough for 1 plate. AldeLight™ Green working solution is not stable, and best used within 2 hours.
SAMPLE EXPERIMENTAL PROTOCOL
Table 1. Layout of Formaldehyde standards and test samples in a solid back 96-well microplate. FS= Formaldehyde Standards (FS1 - FS7, 0.41 to 300 µM), BL=Blank Control, TS=Test Samples.

Table 2. Reagent composition for each well.
Well | Volume | Reagent |
FS1 - FS7 | 50 µL | Serial Dilutions (0.41 to 300 µM) |
BL | 50 µL | Assay Buffer |
TS | 50 µL | test sample |
- Prepare Formaldehyde standards (FS), blank controls (BL), and test samples (TS) according to the layout provided in Tables 1 and 2. For a 384-well plate, use 25 µL of reagent per well instead of 50 µL.
- Add 50 µL of AldeLight™ Green working solution to each well of Formaldehyde standard, blank control, and test samples to make the total Formaldehyde assay volume of 100 µL/well. For a 384-well plate, add 25 µL of AldeLight™ Green working solution into each well instead, for a total volume of 50 µL/well.
- Incubate the reaction at room temperature for 20 to 60 minutes, protected from light.
- Monitor the fluorescence increase with a fluorescence plate reader at Ex/Em = 410/525 nm (Cutoff = 495nm).
