The catecholamines are released by the sympathetic nervous system and adrenal medulla to the circulating blood. The supernatant fluid is utilized for characterization studies. After the 30 seconds remove the banana from the boiling water and observe it.
Pour the saltwater mix into the bag. The studied analyte in this work was the adrenaline which reacts with oxygen in the presence of PPO. Add ten small chunks of fresh pineapple to one bowl.

Store at 4 to retain at least 70 of PPO activity for 1 month. Now transfer the material in the incubation mixture made of 5 benzidine saturated solution 5 ml hydrogen peroxide 1 and 1 ml ammonium chloride 5. Cut thin sections of fast-growing roots or germinating seeds or take some pollen grains and put the material in phosphate buffer at pH 70.
