acid was placed in the centre of a paper strip, moistened with buffer of pil 6 and electric current
applied. The migration of amino acids was as follows:
(A) Glycine, lysine and histidine moved towards the anode. Aspartic acid and glutamic acid moved
towards the cathode while arginine remained near the origin.
(B) Aspartic acid and glutamic acid remained near the origin and lysine, histidine and glycine moved
towards the anode while arginine moved towards the cathode.
(C) Glycine remained near the origin. Lysine, arginine and histidine moved towards the cathode while
