Abstract

Modifications and adaptations of chemical techniques have been used to quantitate hydroxyproline (collagen), total protein and DNA in fixed, paraffin-embedded and sectioned tissue. The assays are rapid and sensitive to between 0.1 and 1.0 μg of each of the three components. Values for the ratio of collagen to total protein or collagen per DNA obtained from sectioned material are the same as values derived from fresh or fixed starting material. Depending on the tissue and the sample size, as little as three to five 5 μm thick sections can be analysed for these three components. The ratios of collagen per total protein or collagen per DNA are given for several murine tissues. The assay of these components in tissue sections will allow a more precise correlation between histological appearance and the quantitative biochemical changes that may accompany many pathological disorders. The techniques are particularly useful in retrospective studies where the experimental material may be en bloc.
