Simple and rapid thin-layer chromatographic methods, using heel or finger-tip blood, are describedthat are suitable for screening for inborn errors of amino acid metabolism. Serum is chromatographed without deproteinizing. A variation of this method utilizes blood impregnated on paper discs for chromatography. These methods are much faster, more sensitive, and provide better resolutionof amino ...

The method for assaying thymine-containing dimers in yeast is based on highly efficient ([3H]-deoxythymidine-5'-monophosphate) DNA-specific labelling and employs ascending thin layer chromatography. It allows satisfactory quantitative analysis down to UV-doses of 500 erg/mm2.

Purification by flash chromatography strongly impacts the greenness of a process. Unfortunately, due to the lack of the relevant literature data, very often this impact cannot be assessed thus preventing the comparison of the environmental factors affecting the syntheses. We developed a simple mathematical approach to evaluate the minimum mass intensity of flash chromatography from the retentio...

in the present study, an oxidative conversion of non-fluorescent dichlorofluoroscein (ldcf) to fluorescent dichlorofluoroscein (dcf) was used for detection of antioxidant properties of plant extracts. the rate of the reaction was followed by monitoring the formation of dcf as a function of time. the antioxidant assay was carried out for different concentrations of gallic acid, salvia mirzayanii...
