Preparation of HRP-Streptavidin Conjugate (SABC) Working Solution

1.Add 100µL of standard or sample per well. Cover with the adhesive strip provided. Incubate for 2 hours at 37°C.
2.Remove the liquid of each well, don't wash.
3.Add 100µL of Biotin-antibody (1×) to each well. Cover with a new adhesive strip. Incubate for 1 hour at 37°C.
4.Aspirate each well and wash, repeating the process two times for a total of three washes.After the last wash, remove any remaining wash Buffer by aspirating or decanting. Invert the plate and blot it against clean paper towels.
5.Add 100µL of HRP-avidin (1×) to each well. Cover the microtiter plate with a new adhesive strip. Incubate for 1 hour at 37°C.
6.Repeat the aspiration/wash process for five times as in step 6.
7.Add 90µL of TMB Substrate to each well. Incubate for 20 minutes at 37°C. Protect from light.
8.Add 50µL of Stop Solution to each well, gently tap the plate to ensure thorough mixing.
9.Determine the optical density of each well within 5 minutes using a microplate reader set to 450nm.

Calculate the mean absorbance for each set of duplicate standards, controls and samples, and subtract the average zero standard optical density. Plot the standard curve on log-log graph paper or using Sigma plot software, with standard concentration on the x-axis and absorbance on the y-axis. Draw the best-fit straight line through the standard points.
