This invention relates to compositions and methods useful for measuring pH generally, and intracellular pH specifically, and, more particularly, to a new class of fluorescent and fluorinated (NMR sensitive) aromatic compounds having excitation emission wavelengths in the ultraviolet or or visible portions of the electromagnetic spectrum, useful as pH indicators, as well as fluorine containing analogs useful in NMR spectroscopic determinations.
这项发明涉及用于测量pH值,特别是细胞内pH值的组合物和方法,更具体地说,是一种新型的含有荧光和氟化(对核磁共振敏感)的芳香化合物,其激发发射波长位于电磁谱的紫外或可见光部分,可用作pH指示剂,以及含有氟的类似物,在核磁共振光谱测定中非常有用。
