title: Identification of actin isoforms after in situ hydroxylamine cleavage on sequencer membranes: serum actin is a cytoplasmic isoform.
abstract: Actin was isolated from fetal bovine serum by means of affinity chromatography on DNase I-Sepharose, reversed phase chromatography and SDS-gel electrophoresis. It was identified as a cytoplasmic isoform by direct micro sequence analysis of hydroxylamine cleavage products which had been generated in situ after covalent linkage of the protein to sequencer membrane disks through arylamine or isothiocyanato functionalities.
