Figure 3. Representative data using the BER THF Molecular Beacon.
AP endonuclease activity specific for hydrolysis of the abasic site analog tetrahydrofuran (THF) 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 THF Molecular Beacon (LN428, blue; LN428/MPG, red). Results are reported as (A) the mean fluorescence response units and (B) the same data normalized to beacon input as described in Section 4 above (THF = tetrahydrofuran).
