2-p-Toluidinonaphthalene-6-sulfonate with Cationic Detergents
2-p-Toluidinonaphthalene-6-sulfonate (TNS), a well-known fluorescent probe, forms premicellar aggregates with detergents such as cetyltrimethylammonium bromide (CTAB) at concentrations just below their critical micelle concentration. A narrow fluorescent band, very small Stokes shift, and very high quantum yield are the characteristics of the hydrophobic environment provided by the premicellar ...
متن کاملBenzyltributylammonium 6-hydroxynaphthalene-2-sulfonate
The title compound, C(19)H(34)N(+)·C(10)H(7)O(4)S(-), is a charge-control agent for toners used in electrophotography. Inter-moleclar O-H⋯O hydrogen bonding between the OH group of one anion and the sulfonate O atom of a neighboring anion leads to the formation of one-dimensional chains along the b axis. In addition, C-H⋯O hydrogen bonds are observed. One of the n-butyl chains of the cation is ...
متن کاملP-11: DHR123: A Suitable Fluorescent Mitochondrial Probe for Assessment of H2O2 in Human Spermatozoa
Background: The objective of present study was to assess potential of DHR123 (dihydrorhodamine 123) fluorescent probe for measurement of H2O2 produced by human spermatozoa and comparing the results with DCFH-DA (2', 7'-dichlorodihydrofluorescein diacetate). Materials and Methods: Fluorescent intensity and percentage R123 and DCF positive sperm measured by flow cytometry. The suitable ...
متن کاملReaction of Cystathionase with the Fluorescent Probe
The enzyme cystathionase from rat liver is inactivated by incubation with 5,5’-dithiobis(Z-nitrobenzoic acid) at pH 7.4. The reaction of four -SH groups per mole of enzyme brings about 95% loss of the homoserine deaminase activity. Kinetically, the reactive --SH groups can be classified into two classes. The substrate L-homoserine or the competitive inhibitor L-alanine has no effect on the rate...
متن کاملInteraction of CORM-2 with hydrophobic sites: Beyond CO
Carbon monoxide releasing molecules (CORMs) have been recently developed for research and pharmacological purposes. A considerable amount of studies demonstrated a wide spectrum of biological activities for lipophilic CORM-2 (tricarbonyldichlororuthenium (II) dimer). It is generally accepted that the liberated gas provides the specific activities to CORMs, with a little attention paid to any po...
