Application Details

Sample Volume: 100 µL

Assay Time: 1 d

Plate: Uncoated

Protocol:

1. Take out the Micro ELISA pre-Plate, add 100 µL Capture antibody working solution to each well. Incubate overnight at 2-8°C.
   Discard the liquid, add 200 µL ELISA Plate Blocking Buffer to each well. Incubate for 60 min at 37°C
2. Discard the liquid, add 100 µL standard or sample to the wells. Incubate for 90 min at 37°C
3. Discard the liquid, immediately add 100 µL Biotinylated Detection Ab working solution to each well. Incubate for 60 min at 37°C
4. Aspirate and wash the plate 3 times
5. Add 100 µL HRP conjugate working solution. Incubate foe 30 min at 37°C. Aspirate and wash the plate for 5 times.
6. Add 90 µL Substrate Reagent. Incubate for 15 min at 37°C
7. Add 50 µL Stop Solution
8. Read the plate at 450 nm immediately. Calculation of the results
