abstract：:Placental alkaline phosphatase is an inducible enzyme, expressed in HeLaS3 cells, which has been shown to possess protein phosphotyrosine phosphatase activity. Since phosphotyrosine levels are known to increase in actively dividing cells we sought an inverse correlation between PLAP activity and growth rate in HeLaS3 ...
