Analytical Volumetric Solutions and Indicators

Stability Light Sensitive, Hygroscopic
Applications A fluorescent reagent for the detection of proteins having Histidine-tag (his-tag).
References Amano, H., et al.: Analytical Sciences, 17, Supplement, i1469 (2001)

Stability Light Sensitive
Applications A highly reactive thiol-specific spin-label. A specific conformational probe of thiol site structure by virtue of its minimal rotational freedom and distance from the covalent disulfide linkage to the macromolecule under study.

Applications A spin label.

Applications Fast Blue B Salt is a stain that is used for the determination of various compounds. It has been used to demonstrate esterase activity. Histochemically it has stained enterochromaffin cells and cells that have gone under free radical oxidative damage. It can be used as reactant/reagent in one pot preparation of phenanthroline-based shape-persistent fluorescent macrocycle using Sonogashira coupling. Dyes and metabolites.

Applications The Fluorescein Arsenical Hairpin Binder (FlAsH) method is presented for fluorescence labeling of proteins in living cells. Labeling proteins with the membrane-permeant fluorogenic biarsenical dye fluorescein arsenical hairpin binder-ethanedithiol (FlAsH-EDT2). The membrane-permeant fluorogenic biarsenicals FlAsH-EDT2 and ReAsH-EDT2 can be prepared in good yields by a straightforward two-step procedure from the inexpensive precursor dyes fluorescein and resorufin.
