| Abstract: | Total proteins of human platelets and their membranes were studied by two-dimensional electrophoresis using the lysis in sodium dodecyl sulfate solution. Analysis of platelets from 30 donors revealed the presence of 105 repeating fractions on the electrophoregrams. A two-dimensional map of platelet proteins in the molecular mass versus relative electrophoretic mobility plot was constructed. This map made it possible to localize membrane proteins and albumin as well as a protein immunologically related to phenylalanine hydroxylase. Electrophoretic variants of 13 platelet polypeptides were identified. |
