in order to elucidate whether chromosomal change or induction of differentiation is correlated with the change of the patterns of cell surface glycoproteins and asparagine-linked sugar chains , glycoproteins and carbohydrates of five rat erythroleukemic cell lines ( k1db , d5a1 , k2d , k2da , and k4d ) were studied by sodium dodecyl sulfate : polyacrylamide gel electrophoresis and hydrazinolysis followed by gel chromatography , respectively .
