There are several common ways in which intracellular pH (pHi) can be measured including with a microelectrode, dye that is sensitive to pH, or with nuclear magnetic resonance techniques. For measuring pH inside of organelles, a technique utilizing pH-sensitive green fluorescent proteins (GFPs) may be used. Overall, all three methods have their own advantages and disadvantages. Using dyes is perhaps … WebHere we show, using a pH-sensitive green fluorescent protein (GFP), that mitochondria-dependent apoptotic stimuli (such as Bax, staurosporine and ultraviolet irradiation) induce rapid, Bcl-2-inhibitable mitochondrial alkalinization and cytosol acidification, followed by cytC release, caspase activation and mitochondrial swelling and depolarization.

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. WebMy understanding is that the pH in the human cell and in the human body is around 7. The reason the intermembrane space would have such a low pH is due to proton pumping that occurs during oxidative phosphorylation and the increase in proton concentration in the intermembrane space. great wolf lodge philadelphia pa great wolf lodge pet policy
