Figure 3. In situ hybridization on human sperm using HPV type-specific probes.

Figure 3

Specific hybridizations are indicated by arrows. (A–C): In situ hybridization on an HPV-16 positive sperm sample using a probe specific for HPV-16. The sample in picture A was simultaneously background stained with hematoxylin. (D–I): In situ hybridization on an HPV-6 positive sperm sample using a probe specific for HPV-6. (J–L): In situ hybridization on an HPV negative sperm sample using a probe specific HPV-6. This figure is a representative of three independent in situ hybridization experiments using two different HPV-6 positive samples and two different HPV-16 positive samples.
