Selective Sensing of Tyrosine Phosphorylation in Peptides Using Terbium(III) Complexes

Figure 6

Time-dependent change of the luminescence intensity from -L¹ for the dephosphorylation of P1-pY by Shp-1 tyrosine phosphatase. [Shp-1] = 100 (pink) and 10 ng/mL (cyan). [P1-pY] = 10 μM and [-L¹] = 100 μM. The excitation at 262.5 nm and the emission at 545 nm. Reprinted with permission from [69]. Copyright 2014, Springer.
