FIG. 2.

Dilution series of HPV16 (10⁶ to 10⁻¹ copies). Comparison of sensitivity between paraffin- and non-paraffin-embedded material performed by conventional PCR and real-time PCR visualized on gel. Rows: A, conventional PCR, paraffin-embedded material (DNA from archival HPV-negative cervical cancer tissue sample); B, conventional PCR, non-paraffin-embedded material (DNA from HeLa-cells); C, real-time PCR, paraffin-embedded material (DNA from archival HPV-negative cervical cancer tissue sample); D, real-time PCR, non-paraffin-embedded material (DNA from HeLa cells).
