50 µL Primary Antibody Solution

3.   Add 50 µL of Primary Antibody Solution to all wells except the non-specific binding (NSB) wells. Cover with a plate sealer, and incubate at room temperature for 1 hour on a horizontal orbital microplate shaker.
4.   Aspirate each well of the microplate and wash, repeating the process 3 times for a total of 4 washes.

50 µL of Calibrator Diluent

7.   Add 50 µL of the Calibrator Diluent to the NSB and zero standard (B₀) wells.

---

50 µL Conjugate

8.   Add 50 µL of Conjugate to all wells. Cover with a new plate sealer, and incubate at room temperature for 2 hours on the shaker.
9.   Aspirate and wash 4 times.
