(A)Migration of labeled C and its 5-position modified forms by TLC under the first developing buffer. Lanes 1-3 serve as controls for the migration of 5mC and 5hmC generated from DNA oligos incubated with wild-type or catalytic mutant Tet2.
(B) The same samples used in panel A were separated by TLC under the second developing buffer. With the exception of 5mC and C, all of the other forms of C can be separated under this condition.
(C) Autoradiographs of 2D-TLC analysis of samples derived from 5mC-containing TaqI 20mer oligo DNA incubated with wild-type and catalytic-deficient mutant Tet1, Tet2, and Tet3.
