in order to screen human tumor cells for putative cell surface marker molecules , the glycoprotein composition of in vitro cultivated human tumor cell lines of different origin ( 12 carcinomas , one neuroblastoma , one melanoma and one sarcoma ) was analyzed by metabolically labelling the cells with [ 3h ] galactose , [ 3h ] mannose and [ 3h ] fucose and subsequently separating the labelled material by sds-page .
