应用

BCECF 的细胞渗透性酯,通过胞质酯酶水解,产生胞内捕获的 pH 指示剂 BCECF。允许同时记录单个骨肉瘤细胞的细胞体积变化和细胞内 pH 值。
一种不带电的、无荧光的分子,对细胞悬液的非侵入性批量加载有帮助,因为它能透过细胞膜。细胞非特异性酯酶裂解其亲脂性阻断基团,产生带电荷的分子荧光形式。与母体化合物相比,这种带电荷的衍生物以慢得多的速率漏出电池。用于测定灌注组织、细胞间隙 、哺乳动物细胞 、植物细胞、细菌和酵母菌的 pH 值。此外,还用于研究细胞功能属性试验,如粘附、多药耐药性、活力和细胞毒性、细胞凋亡和趋化性

The strictly aerobic, polyphosphate-accumulating Acinetobacter johnsonii strain 210A degrades its polyphosphate when oxidative phosphorylation is impaired. The endproducts of this degradation, divalent metal ions and inorganic phosphate, are excreted as a neutral metal-phosphate (MeHPO4) chelate via the electrogenic MeHPO4/H+ symport

We have tested the efficacy of fluorescent probes for the measurement of intracellular pH in Saccharomyces cerevisiae. Of the compounds tested (fluorescein, carboxyseminaphthorhodafluor-1 (C.SNARF-1) and 2',7'bis(carboxyethyl)-5(6')-carboxyfluorescein), C.SNARF-1 was found to be the most useful indicator of internal pH.

The lateral intercellular spaces (LIS) of reabsorptive epithelia are the site of the proposed local osmotic gradient responsible for transepithelial transport. We developed techniques for loading the LIS of living cultured renal cells (MDCK and LLC-PK1) with the fluorescent dye

The cytoplasmic pH of Lactococcus lactis was studied with the fluorescent pH indicator 2',7'-bis-(2-carboxyethyl)-5 (and-6)-carboxyfluorescein (BCECF). A novel method was applied for loading bacterial cells with BCECF, which consists of briefly treating a dense cell suspension with acid in the
