title: Ways of collagen separation in pathologically altered tissue.
abstract: A system of chromatographic methods using two successive DEAE-cellulose chromatographic steps and two successive separations on Bio-Gel A-1.5 m has been worked out for the separation of individual collagen types. The success of the procedure is based on the preliminary removal of proteoglycans during the first DEAE-cellulose run. Alternatively it is possible to replace chromatographic steps, following the removal of proteoglycans, with fraction precipitation.
