Activity of 5-MCDG from nuclear extracts. Average values (triplicates)
obtained by cutting out the specific band (27-mer) from the gel and
measuring the radioactivity. (Inset) Separation of the
reaction product (27-mer) on a sequencing gel (20% polyacrylamide).
Lanes: 1, parent cell line; 2, cell line transfected with the empty
vector; 3, cell line transfected with the inactive mutant of 5-MCDG; 4,
cell line transfected with the 5-MCDG; 5, blank.
