WebThe pH inside human cells (6.8) and the pH of blood (7.4) are both very close to neutral. Extreme pH values, either above or below 7.0, are usually considered unfavorable for life. However, the environment inside your … WebThe most widely used pH dye is 2′,7′-bis- (2-carboxyethyl)-5- (and-6)-carboxyfluorescein, which possesses a pKa of ~ 7.00. This is close to the intracellular pH and enables the monitoring of pH in an optimal dynamic range. This dye has its excitation maximum at a wavelength of ~ 490 nm, which shows pH sensitivity.
