Figure 4. Representative data using the BER Hx Molecular Beacon.
DNA glycosylase activity specific for removal of the MPG substrate hypoxanthine (Hx) was measured in nuclear lysates from the control cell line (LN428) and the MPG over-expression cell line (LN428/MPG). Each lysate was analyzed using either the BER Molecular Beacon Control (LN428, green; LN428/MPG, purple) or the BER Hx Molecular Beacon (LN428, blue; LN428/MPG, red). Results are reported as (A) the mean fluorescence response units and (B) the same data normalized as described in Section 4 above (Hx = hypoxanthine).
