应用
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。
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。

The tumor interstitial pH and its modification play a significant role in cancer treatment. Current in vivo pH measurement techniques are invasive and/or provide poor spatial resolution. Therefore, there are no data on perivascular interstitial pH gradients in normal or

We have used the pH-sensitive, fluorescent, cytoplasmic-trapped dye 2',7'-bis(carboxyethyl)-5(6)-carboxyfluorescein (BCECF) to identify Na+-H+ exchange in gastric glands isolated from rabbit stomachs by high-pressure perfusion and collagenase digestion. The fluorescence of BCECF-loaded glands was calibrated in terms of cytosolic pH (pHc)

The mammalian cDNA encoding alpha (1,3)-fucosyltransferase (alpha (1,3)Fuc-T) termed ELAM-1 ligand fucosyltransferase (ELFT) or Fuc-TIV was previously cloned by three groups who reported different results from transfection studies Goelz et al. (Goelz, S. E., Hession, C., Goff, D., Griffiths, B.

A cytotoxicity assay has been developed based on the measurement of the proliferative activity of surviving cells as quantified by a cell-incorporated fluorescent dye, 2',7'-bis-(2-carboxyethyl)-5(6)-carboxyfluorescein (BCECF). The BCECF proliferative assay is fast (the results are obtained within 3-4 days depending

Intracellular pH (pHi) has been measured in intact, perfused rat mandibular salivary glands loaded with the fluorescent pH indicator BCECF [2',7'-bis(2-carboxyethyl)-5(6)- carboxyfluorescein]. Glands mounted in the cuvette of a conventional bench-top spectro-fluorometer were perfused for 5 min with the acetoxymethyl
