It is extremely challenging to quantitate lumenal Ca2+ in acidic Ca2+ stores of the cell because all Ca2+ indicators are pH sensitive, and Ca2+ transport is coupled to pH in acidic organelles. We have developed a fluorescent DNA-based reporter, CalipHluo
To examine the dynamic and local nature of soil pH during drying, we conducted a series of proof of concept tests by measuring the pH of buffer solutions and wet quartz sand (sterilised) under two wet–dry cycles (see Methods, Supplementary Figs. 3 and 4). The primary objective of this ...
