This Article contains an error in the equation for estimating the 5 hmC/C ratio, R.

In the Results section, “Determining hmC content in murine genomic DNA”

$$ R = \frac{{\alpha \left( {{\raise0.7ex\hbox{${c^{\prime } }$} \!\mathord{\left/ {\vphantom {{c^{\prime } } {c_{o} }}}\right.\kern-\nulldelimiterspace} \!\lower0.7ex\hbox{${c_{o} }$}}} \right)}}{{2lY}} $$

should read:

$$R=\frac{\left(\frac{{c}{\prime}}{{c}_{o}}\right)}{2lY\mathrm{\alpha }}$$
