The positive reaction of F-cells to Mercuric Bromophenol Blue confirms their role in digestive enzyme production.
The supernatants thus obtained were submitted to SDS-PAGE [7] followed by electrophoresis at 70 V until the bromophenol blue dye front reaches the bottom of the gel.
01 mM bromophenol blue was added to the samples to yield a final concentration of 0.
05% bromophenol blue was added to stop the reaction and the reaction mixtures was electrophoresed on 1% agarose gel, and the DNA in the gel was visualized and photographed under ultraviolet light after ethidium bromide staining.
