Although many types of vesicles are similar in size and density , it is
possible to isolate specific types of vesicles throught the use of
a. a fluorescent activated cell sorting machine
b. antibodies attached to bacterial carriers and low speed centrifugation
c. ultracentrifugation
d. light microscopy
答案為b,不太了解怎麼會扯到細菌?是說剛好有吞噬細菌的vesicle可以用這樣分離嗎?
