Genotypic Diversity and Virulence Traits of Streptococcus mutans Isolated from Carious Dentin after Partial Caries Removal and Sealing

Figure 2

Electrophoresis gel image from AP-PCR-generated fingerprints using primer OPA-02 of S. mutans reference strain (UA159) and isolates from carious dentin before and after sealing. Lanes 1 to 15 correspond to the S. mutans isolates before sealing; lanes 16 to 20 correspond to the S. mutans isolates after sealing; lane 21: negative control (water); lane 22: 250-bp DNA ladder.
