analysis by means of two-dimensional gel electrophoresis ( ief ) of [ 32p ] orthophosphate-labeled proteins from mitotic and interphase transformed amnion cells ( ama ) has shown that keratins ief 31 ( mr = 50,000 ; hela protein catalogue number ) , 36 ( mr = 48,500 ) , 44 ( mr = 44,000 ) , 46 ( mr = 43,500 ) , as well as vimentin ( ief 26 ; mr = 54,000 ) are phosphorylated above their interphase level during mitosis .
