title: Synthesis of fluorescent substrates for protein tyrosine phosphatase assays.
abstract: Two fluorescent substrates for protein tyrosine phosphatase (PTPase) reaction were prepared by conjugation of commercially available O-phosphotyrosine and dansyl chlorides. They were hydrolyzed by CD45 tyrosine phosphatase, and proved to be useful for PTPase assay.
