FTP, name this method of separating molecules by applying them to filter paper or gel and subjecting them to an electric field.
In this method, if one molecule is larger than another, its increased mass will cause it to move more slowly toward the cathode or anode. Spraying the end result with ninhydrin will cause previously colorless amino acids to form colored spots. Amino acids with an isoelectric point greater than the buffered solution will move toward the cathode because of their positive charge.
