Optical pH Sensor Based on Quinizarin for Alkaline pH Regions
The development of an optical pH sensor based on immobilization of quinizarin (1,4-dihydroxyanthraquinone) on a triacetylcellulose membrane was described. The resulting membrane exhibited fast color change from yellow to violet, while changing the pH in alkaline region. The immobilized quinizarin showed a broader dynamic range from (pH 9.4-11.4) with respect to free form (pH 8.8-10.4). The sens...
متن کاملRegulation of intracellular pH.
The approach that most animal cells employ to regulate intracellular pH (pH(i)) is not too different conceptually from the way a sophisticated system might regulate the temperature of a house. Just as the heat capacity (C) of a house minimizes sudden temperature (T) shifts caused by acute cold and heat loads, the buffering power (beta) of a cell minimizes sudden pH(i) shifts caused by acute aci...

متن کاملMetabolic regulation via intracellular pH.
Despite earlier notions that intracellular pH (pHi) was invariant with time, recent studies have documented pHi changes of from 0.1 to 1.6 U during metabolic and developmental transitions in a variety of cells. Here we review the evidence for pHi-mediated regulation of gamete activation, cellular dormancy, the cell cycle, and stimulus-response coupling. Intracellular Ca2+ level changes also acc...
