Determination of proteins with Fast Red VR by a corrected resonance light-scattering technique.
A simple corrected resonance light-scattering (CRLS) technique was established to correct for any distortion of the resonance light scattering (RLS) spectra resulting from molecular absorption. By using an absorption cell holder to change the propagation direction of the incident light beam of a common spectrofluorometer, the molecular absorption was directly measured through a spectrofluoromet...
متن کاملA resonance light-scattering determination of proteins with fast green FCF.
The interaction of Fast Green FCF (FCF) with proteins (including bovine serum albumin (BSA), human serum albumin (HSA), pepsin (Pep) and alpha-chymotrypsin (Chy), and lysozyme (Lys)) was characterized by enhanced resonance light-scattering (RLS) measurements using a common spectrofluorometer. The enhanced RLS signals of FCF by proteins at 279.0 nm were obtained, and the mechanism of the RLS enh...
متن کاملDetermination of antibacterial ofloxacin in human serum samples by a resonance light scattering technique with alizarin violet 3B.
A method for the determination of ofloxacin (OFL) has been developed, based on the enhancement of resonance light scattering (RLS) of OFL in the presence of alizarin violet 3B (AV3B). Under the experimental conditions, the RLS intensity of AV3B was greatly enhanced by adding OFL. At pH 5.09, the enhancement of the RLS intensity at 439.5 nm was proportional to the concentration of OFL in the ran...
متن کاملThe Application of Resonance Light Scattering Technique for the Determination of Tinidazole in Drugs
A resonance light scattering technique to determine tinidazole in drugs was developed by tetraphenylboron sodium (TPB). Tinidazole was found to bind B(C(6)H(5))(-) (4) anion and transformed to tinidazole-TPB aggregate which displayed intense resonance scattering light. Effects of factors such as wavelength, acidity, stabilizers, and interferents on the RLS of tinidazole TPB were investigated in...
متن کاملRapid and Sensitive Determination of Trace Chloride Ion in Drinks Using Resonance Light Scattering Technique
A resonance light scattering (RLS) technique to determine chloride ions in drinks was developed. Chloride ions were found to bind Ag(+) forming AgCl aggregates that produced intense resonance scattering light. Effects of factors such as acidity, ionic strength, and coexistent interferents on the RLS of AgCl aggregates were investigated. The pH of solution almost did not affect the production of...
