Abstract
The present invention provides a method for producing purified platelets from a culture of megakaryocytes, comprising a first centrifugal separation step of centrifugally separating the culture at a centrifugal force of 150×g to 550×g, and a second centrifugal separation step of centrifugally separating, at a centrifugal force of 600×g to 4000×g, a liquid component recovered in the first centrifugal separation step.
