Selective proteolytic sensitivity of sulfate-collagen and basement membranes

Sulfation and methylation-sulfation induces proteolytic sensitivity in formolfixed paraffin sections of fibrillary collagen and basement membranes. Other fibrillary elements such as myofibrils, tonofibrils and fibrin as well as the cell elements of connective and parenchymatous tissues are resistant in methylated sulfated sections and remain well preserved… CONTINUE READING
