(e.g. Note: If you are using an aqueous chromogen instead of DAB (i.e. To block endogenous peroxidase activity, quench the tissue sections with 3.0% hydrogen peroxide in methanol for 15 minutes. Incubate sections in two washes of 95% ethanol for 10 minutes each. Permeabilization and Blocking Non-Specific Binding, Deionized Water, two washes for 5 minutes. 2. Agonists, activators, antagonists and inhibitors. Prior to de-paraffinization, the slides are heated to 55°C for ten minutes to melt the wax. 96 0 obj <>stream Monitor the reaction as the chromogenic reaction turns the epitope sites brown (time of color development may vary from few seconds to 10 minutes). Wash sections twice with 1% serum PBS-T for 10 minutes each. Tip: The species of the animal serum used in permeabilization and blocking buffers is dependent on the host of your secondary antibody.
