Web1. If using a HRP conjugate for detection, blocking of endogenous peroxidase can be performed but we recommend waiting until after the primary antibody incubation. H 2 O 2 suppresses endogenous peroxidase activity to reduce background staining. Check for the presence of endogenous peroxidases by incubating a tissue slide WebABC Staining Protocol. Incubate specimens for 1 hour in 5% normal blocking serum in PBS or in UltraCruz® Blocking Reagent ( sc-516214 ). If a conventional secondary antibody is …
WebHow to block endogenous peroxidase activity on frozen sections Immerse slides in fresh made 0.3% hydrogen peroxide in 0.1% sodium azide for 10-15 minutes (to make the blocking solution, add 5ml of 3% hydrogen peroxide to 45 ml of 0.1% sodium azide and mix well). WebDissolve 2 mg of peroxidase in 500 μL of water. 2. Add 100 μL of freshly prepared 0.1 M sodium periodate, and stir the solution for 20 min at room temperature.
