This video demonstrates the separation procedure of heparan sulfates isolated from mouse lung tissue using polyacrylamide gel electrophoresis.
Protocol
1. Polyacrylamide gel electrophoresis of isolated and purified glycosaminoglycans Prepare solutions necessary for polyacrylamide gel electrophoresis (PAGE) in advance (Table 1). NOTE: Select the percent acrylamide of resolving gel solution depending on the size of the glycosaminoglycans expected to be in the sample. 15% is recommended for resolving larger fragments (greater than 30 disaccharide subunits in length); 22% for…
