Analysis of P2Y₁₃ protein expression in human megakaryocytes in culture and in human platelets. CD61+ human megakaryocytes (MK) or washed human platelets were lysed and subjected to western blot analysis. (A) P2Y₁₃ receptor expression in human megakaryocytes on different days of culture. (B) Expression of CD61 and P2Y₁₃ in human megakaryocytes on day 13 of culture and in washed human platelets. Samples were re-probed with anti–β-actin to ensure equal loading (results are representative of 3 different experiments).
