Triton X-100 Permeabilization Buffer Get a 500mL beaker. Weigh out 20 mM HEPES (0.953g), 300mM Sucrose (20.54g), 50mM NaCl (0.584g), 3mM MgCl2 (0.122g) and place in a 500mL beaker. Add 198mL of dH2O. Add 1mL 10% sodium azide solution. Add a magnetic stir bar - mix on stir plate until dissolved. DO NOT add Triton X-100 at this point. After contents are dissolved add 1mL 100% Triton X-100 (0.5% final concentration). Mix slowly until Triton X-100 has dissolved. Pour solution into a 250mL Duran bottle. Label and store in fridge.
