Which of the following is true for Capillary electrophoresis (CE) resolution

#Unit 13. Methods in Biology

Capillary buffer flow take places from anode (+) to (-) cathode
Positive and negative sample molecules migrate at different rates.
Positively charged molecules reach the cathode first because the combination of electrophoretic migration and electro-osmotic flow causes them to move fastest.
Free solution method is the simplest and most widely practiced mode of capillary electrophoresis.
