چکیده
A comparison between two fluorescent metal chelates for staining proteins separated by electrophoresis has been carried out. One of these chelates is ruthenium II tris (bathophenanthroline disulfonate) and the other is commercial Sypro Ruby. Both can be efficiently detected either with UV tables or with commercial laser fluorescence scanners. The sensitivity and homogeneity of the stains and the interference with mass spectrometry analysis have been investigated. It appears that both stains perform similarly for protein detection, while ruthenium II tris (bathophenanthroline disulfonate) performs better for mass spectrometry analyses and as cost-effectiveness ratio. However, Sypro Ruby is easier to use as a stain.

Improvements and simplifications in in-gel fluorescent detection of proteins using ruthenium II tris-(bathophenanthroline disulfonate): the poor man's fluorescent detection method.
Fluorescent detection of proteins is a popular method of detection allying sensitivity, linearity and compatibility with mass spectrometry. Among the numerous methods described in the literature, staining with ruthenium II tris(bathophenanthroline disulfonate) is particularly cost-effective, but slightly cumbersome owing to difficulties in the preparation of the complex and complexity of staini...
متن کاملDirectional photoinduced electron transfer in paraquat silicate thin films containing entrapped ruthenium(II)-tris(bathophenanthroline-disulfonate).
We have demonstrated directional photoinduced electron transfer in paraquat silicate thin films containing entrapped ruthenium(II)-tris(bathophenanthroline-disulfonate (RuBPS). The films were made by electrochemically-induced hydrolysis of a silane analogue of paraquat with ruthenium(II)-tris(bathophenanthroline-disulfonate as its ion pair.

1. An artificial facilitated amino-acid-transfer process operating across a chloroform phase is reported. 2. This process utilizes a family of bis(salicylamidato)copper(II) complexes. 3. A mechanism is proposed for this process and for its sensitivity towards cyanide and bathophenanthroline sulphonate. 4. Facilitated transfer of L-leucine in human erythrocytes has been shown to be inhibited by ...
متن کاملType of Stains Used in Detection of Protein in Gel
Protein separation by two-dimensional electrophoresis (2DE) is largely used in proteomic approaches because of both high resolution and the availability of powerful image analysis software for gel comparison and compatibility with subsequent protein characterization by mass spectrometry [1]. For these various aspects, the selection of the protein staining procedure is of major importance [2]. B...
متن کاملQuantitative proteomics: assessing the spectrum of in-gel protein detection methods.
Proteomics research relies heavily on visualization methods for detection of proteins separated by polyacrylamide gel electrophoresis. Commonly used staining approaches involve colorimetric dyes such as Coomassie Brilliant Blue, fluorescent dyes including Sypro Ruby, newly developed reactive fluorophores, as well as a plethora of others. The most desired characteristic in selecting one stain ov...
