Title:
Are histones the targets for flavan-3-ols (catechins) in nuclei? 
Abstract:
Binding of flavan-3-ols to nuclei is characteristic of Tsuga canadensis (coniferous tree). This is achieved with the DMACA reagent (p-dimethylamino-cinnamaldehyde), which stains almost exclusively monomeric and oligomeric flavan-3-ols with an intense blue colour. Deep flavanol staining also occurred when calf cells of small intestine were enriched with added catechins. In order to detect the components of nuclei that may associate with catechins, the principal components of chromatin (DNA, histo...    »
