For Research Grade Use Only.

1.Calculate the total volume of Capture Antibody needed and dilute to the working concentration in PBS.
2.Immediately add 100 µL of the diluted Capture Antibody or antigen per well. Cover the microplate with the lid and incubate overnight at 2-8 °C.
3.Aspirate each well and wash 3 times with Wash Buffer or PBS (350 µL/well) using a squirt bottle, manifold dispenser, or autowasher. After the final wash, remove any remaining liquid by inverting the microplate and blotting it against a clean paper towel.
4.Block membranes by adding 200 µL of Blocking Buffer to each well. Incubate for 2 hours at room temperature.
5.Aspirate or decant Blocking Buffer. Rinse with the same media in which the cells will be cultured.
6.Aspirate culture media from the microplate, and immediately fill the appropriate wells with 100 µL of culture media containing human IgG secreting cells. Incubate at 37 °C in a 5% CO2 incubator.
7.Wash the microplate 4 times with Wash Buffer. Remove any remaining Wash Buffer by inverting the microplate and blotting it against a clean paper towel.
8.Calculate the total volume of Detection Antibody needed and dilute to the working concentration in Reagent Diluent.
9.Add 100 µL of the diluted Detection Antibody or biotinylated antigen per well. Cover the microplate with the lid and incubate overnight at 2-8 °C.
10.Aspirate Detection Antibody or biotinylated antigen and wash as described in step 3. Microplates are now ready for color development.
