Calibrator Diluent

3.   Add 150 µL of Calibrator Diluent to the non-specific binding (NSB) wells.
4.   Add 100 µL of Calibrator Diluent to the zero standard (B₀) wells.

50 µL Primary Antibody Solution

6.   Add 50 µL of Primary Antibody Solution to each well (except the NSB wells).
7.   Cover with a plate sealer, and incubate at room temperature for 2 hours on a horizontal orbital microplate shaker. Do not wash the plate.

50 µL Conjugate

8.   Add 50 µL of Conjugate to each well. Cover with a plate sealer, and incubate at room temperature for 1 hour on the shaker.
9.   Aspirate each well and wash, repeating the process 3 times for a total of 4 washes.
