Certain Effects of Salts on T H E Penetration of Brilliant Cresy-l Blue into Nitella. by Marian Irwin
The effect of salts on the rate of penetration of dye into living cells has been studied by various investigators I by comparing the rate in dye solution containing salt with that in dye solution containing no salt, but it is not possible to determine from their results whether the salt acts on the protoplasm or on the dye or on both. The writer therefore has suggested a method ~,3 by which we ...

متن کاملBrilliant Cresyl Blue in Sap of Nitella
It has been shown by several investigators I that when the pl-I value of the external dye solutions is increased, the rate of accumulation of a basic dye in the cell sap is accelerated. Two different explanations for this have been given. Some have accounted for it on the basis that the basic dye enters the cell in the form of a dye hydrate and combines with the substances in the cell; and that...
متن کاملIv. Penetration of Brilliant Cresyl Blue into Nitella Flexilis by Marian Irwin
A basic dye is usually obtained in the form of the salt some of which may be transformed in aqueous solution to free base (the m o u n t depending on the "apparent" dissociation constant of the dye and the pH value), and in the range of pH values generally employed with living cells (approximately between pH 5 and 9.5) both forms of dye must be considered. In this range methylene blue, for exam...
متن کاملAccumulation of Brilliant Cresyl Blue in the Sap of Living Cells of Nitella in the Presence of Nh3
When the living cells of Nitella are placed in a solution of brilliant cresyl blue containing NH(4)Cl, the rate of accumulation of the dye in the sap is found to be lower than when the cells are placed in a solution of dye containing no NH(4)Cl and this may occur without any increase in the pH value of the cell sap. This decrease is found to be primarily due to the presence of NH(3) in the sap ...
