Tissue pieces incubated in incubation solution containing 15U/mL papain and
2.5mM cysteine. Following 30min @ RT preincubation of enzyme soln, tissue
pieces added on oscillating (2Hz) culture dish for 45min @ RT. Pieces
transferred to recording soln and triturated through very narrow bore pastuer
pipette (fire-polished). Stored at 6 deg for max 6 hours.
