METHODS. A peptide corresponding to a major heparinand cell-binding domain of the LG4 module of the laminin 5 chain was analyzed. The attachment of conjunctival epithelial cells to the peptide compared with laminin-10 was determined by colorimetric adhesion assay. The role of glycosaminoglycans in mediating adhesion to the peptide was determined by altering their function at the cell surface an...

Carbohydrates are the integral parts of glyco-conjugates and play an important role in cellular functions. 2-Deoxy-D-glucose (2-dGlc) is a sugar analogue of glucose and mannose and is reported to inhibit the lipid-linked saccharide formation involved in N-linked glycosylation of proteins. Administration of 2-dGlc (1 mg/100 g body weight) produced a decrease in the tissue total glycosaminoglycan...

Heparin was isolated from whole clam tissue Marcia opima . Purification of multimilligram quantities of heparin from this tissue sample permitted a thorough examination of its anticoagulant activity characterization, which was partially purified by fractionation by anion exchange chromatography using DEAE cellulose column. The isolated crude and partially purified fractionated sample showed me...
