omputational approach of protein analysis using affinity chromatography: application to proteomics

Computerization is necessary to build the database of chromatography coupled mass spectrometric analytical data. On the basis of this proteomic data we can identify the proteins as biomarkers which are expressing dissimilarity between healthy and disease condition. Affinity chromatography is one of the fastest liquid chromato-graphic methods for the separation and purification of biomolecules due to its high molecular...

Tetrapropylammonium bromochromate and tetrabutylammonium bromochromate [NR4]CrO3Br, (R= Pr, Bu): two new and efficient reagents for oxidation of alcohols

Tetrapropylammonium bromochromate (VI), [N(Pr)4]CrO3Br, TPABC and tetrabutyl-ammonium bromochromate (VI), [N(Bu)4]CrO3Br, TBABC were prepared and used to quantitatively oxidizing of a number of organic substrates. These reagents are versatile reagents for the effective and selective oxidation of organic substrates, in particular for alcohols, under mild conditions.   Key...
