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

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.

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)

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

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
