This article describes a simple method to determine the optimum pH for the activity of one enzyme in a coupled enzyme assay. Decoupling of the two-step reaction is achieved by heat denaturing the ...

For much of nutrition science history, trace minerals were discussed almost exclusively in the context of deficiency diseases ...

Researchers have developed a new class of bioluminescent sensors capable of accurately tracking pH levels inside living mammalian cells, offering a stable, ratiometric alternative to traditional ...
