Fig 3. DSF melting curves of TSVZV with BVDUP.
(a) BVDU could not stabilize TSVZV before phosphorylation but after an in vitro phosphorylation with TKHS, BVDUP increased the Tm of TSVZV by a larger extent than dUMP. (b) Varying concentrations of BVDUP increased the Tm of TSVZV in a dose responsive manner. (c) Further stabilization of TSVZV was observed in the presence of 100 μM raltitrexed with 100 μM of BVDUP.
