Abstrakt: Two resorufin-based substrates for protein tyrosine phosphatase (PTP) activity have been synthesized. These substrates provide sensitive fluorogenic readouts of PTP activity in vitro and in living cells at both acidic and neutral pH. In addition, the presence of the pathogenic bacteria Staphylococcus aureus was detected visually using a colorimetric readout. [ABSTRACT FROM AUTHOR]
