100 µL Estradiol Primary Antibody Solution

3.   Add 100 µL of Estradiol Primary Antibody Solution to each well (excluding the 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 and wash, repeating the process 3 times for a total of 4 washes.

50 µL Estradiol Conjugate

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