Red blood cells deposit membrane components on contacting surfaces

An investigation of red blood cell interactions with "foreign" surfaces is reported. Experiments consisted of flowing suspensions of washed human red cells through a packed column of either glass or siliconized glass beads. Conditions were chosen so that hemolysis was minimized. The column was washed to remove suspended red blood cells and then eluted. Samples of beads were examined by SEM after washing and before elution. The eluate was …
