Erythrocyte membrane tropomyosin. Purification and properties.

Two polypeptides of Mr approximately 29,000 and 27,000 have been identified in human erythrocyte membranes that cross-react specifically with affinity purified antibodies to chicken gizzard tropomyosin. The cross-reacting polypeptides are quantitatively retained on the membrane after cell lysis if millimolar concentrations of magnesium are included in the… CONTINUE READING
