Although many types of vesicles are similar in size and density,it is possible to isolate specific types of vesicles through 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.

Question

Quizplus · Accepted Answer

Antibodies can be attached to bacterial carriers that selectively bind to specific surface proteins on vesicles of interest. When mixed with a sample containing various types of vesicles and subjected to low speed centrifugation, the vesicles of interest will be pulled down with the bacterial carriers, allowing for their isolation. This technique is known as immunoisolation. A fluorescent-activated cell sorting machine can also be used, but it is more expensive and not as commonly used for vesicle isolation. Ultracentrifugation is a general technique used to separate particles based on size and density, but it cannot selectively isolate specific types of vesicles. Light microscopy is not a technique used for vesicle isolation.
