Application

Fluo-3 and related molecule Fluo3/AM are used as a fluorescence indicator of intracellular calcium (Ca2+). Fluo-3 may be use for flow cytometry and confocal laser scanning microscopy using visible light excitation (compatible with argon laser sources operating at 488 nm). Fluorescence intensity increases about 40-fold after calcium binding.

Autres remarques

Biomaterial modifications-chemical and topographical-are of particular importance for the integration of materials in biosystems. Cells are known to sense these biomaterial characteristics, but it has remained unclear which physiological processes bio modifications trigger. Hence, the question arises of whether the

Cytoplasmic free calcium [( Ca2+]i) is a key intracellular messenger in many cell types. We have used fluo-3, a recently developed calcium probe, to study [Ca2+]i in resting and stimulated human peripheral blood T lymphocytes. The spectral properties of fluo-3

Mitochondrial superoxide dismutase 2 (SOD2) is a major antioxidant defense enzyme. Here we provide evidence that SOD2 plays critical roles in maintaining calcium homeostasis in newly generated embryonic cerebral cortical neurons, which is essential for normal mitochondrial function and subcellular

Retinoic acid (RA)-induced dermatitis is the most frequent side-effect limiting its widespread use. However, the exact mechanisms triggering dermatitis are not fully understood, including the role of skin mast cells.

A new group of fluorescent indicators with visible excitation and emission wavelengths has been synthesized for measurements of cytosolic free Ca2+. The five compounds, "rhod-1," "rhod-2," "fluo-1," "fluo-2," and "fluo-3" (Figs. 2 and 3), combine the 8-coordinate tetracarboxylate chelating site
