ELISA Chromogenic Reaction Procedure：
Measurement at 450 nm:
1. Wash: After HRP conjugate incubation, wash the plate 3 times with PBST/TBST washing buffer (containing surfactant).
2. Chromogenic reaction: Add 100 μL substrate and incubate at 20–37 °C for the appropriate time, color is blue;
3. Stop: Add 100 μL TMB Stop Solution 450, the color will change yellow;
4. Read: Measure the absorbance at 450 nm within 30 minutes.
Measurement at 650nm：
1. Wash: After HRP conjugate incubation, wash the plate 3 times with PBST/TBST washing buffer (containing surfactant).
2. Chromogenic reaction: Add 100 μL substrate and incubate at 20–37 °C for the appropriate time, color is blue;
3. Stop: Add 100 μL TMB Stop Solution 650, the color remains blue ;
4. Read: Measure the absorbance at 650 nm within 30 minutes.
Kinetic measurement at 650 nm:
1. Wash: After HRP conjugate incubation, wash the plate 3 times with PBST/TBST washing buffer (containing surfactant).
2. Chromogenic reaction: Add 100 μL substrate and incubate at 20–37 °C.
3. Read: Measure the absorbance at 650 nm at set intervals (e.g., every 1 minute).
