Webb6 jan. 2024 · An enzyme-labeled primary antibody (e.g. HRP-labeled primary antibody) specific for the target antigen is added to the wells and directly binds to the antigen. A respective enzyme substrate (e.g. TMB ( 11012 ) a suitable substrate for HRP) is added, which upon reaction with the enzyme, produces a visible colorimetric output that can be … WebbThen, the antibody to the protein of interest is added, incubated, and the excess is washed out. Next, the detection antibody (which binds to the primary antibody) is added, incubated, and the excess is washed out. The last step is to add the detection dye (which binds to the detection antibody) to the wells and allow it to incubate.
