WebDCPIP (2,6-dichlorophenol indophenol) is a dye able to accept electrons from a variety of donors. When DCPIP is oxidized, it is blue. Reduced DCPIP is colorless. The reduction of DCPIP by electrons derived from H2O coupled with the production of O2 is known as the Hill Reaction. By following the rate of conversion of DCPIP from a blue (oxidized ... WebPour off the extra liquid that surrounds the pellet, and resuspend the pellet with around 2cm³ of the isolation medium. This is your leaf extract solution. In each test tube, add 0.5cm³ of the new leaf extract solution. Then, add 5cm³ of either DCPIP or methylene blue indicator into each test tube.
