Figure 1.
Crosslinked plasmid DNA was replicated for 60 minutes in HSS/NPE and then incubated with a range of formaldehyde concentrations in the Formaldehyde Crosslinking Buffer (see Step 3.3-1) prior to immunoprecipitation with anti-RPA antibodies [9]. Percent recovery of DNA near the crosslink is plotted for each formaldehyde concentration tested.
