A dotblot showing a mixture of erythrocytes and erythrocyte-derived microparticles (X-axis-brightfield area; Y-axis-brightfield aspect ratio of intensity). a.) Multiple erythrocytes (region R3 on dotblot); b.) Single erythrocytes (region R2 on dotblot); c.) Microparticles (brightfield) (region R1 on dotblot); d.) Microparticles stained with calcein AM (images from calcein AM-channel are particles taken from R1-region).
