Endo, M. and Yosizawa, Z. A Method for Micro-Scale Isolation of Sulfated Glycopeptide from Tissue. Tohoku J. exp. Med., 1979, 129 (3), p.225-231 Micro-scale isolation of sulfated glycopeptide from tissue was achieved by successive application of pronase digestion (Step 1), cetylpyridinium chloride-fractionation (Step 2), crude heparinase digestion or chondroitinase ABC digestion plus nitrous acid treatment (Step 3) and preparative cellulose acetate membrane-electrophoresis (Step 4). By this method, sulfated glycopeptide was obtained in a high yield from estrogen-treated rabbit uterus. sulfated glycopeptide; rabbit uterus. © 1979, Tohoku University Medical Press.
