- BCD - bisulfite converted DNA; NR – not relevant (no CpG in the genomic sequence); strikethrough – mismatch between the probe and the interrogated locus; italics – incorporated fluorescently labeled ddNTPs (C, G – green = methylation signal; A, T – red = unmethylation signal); dots adjacent to the 3′-most position of the probe indicate no probe extension; “RC” in the probe sequence represents degenerated sites complementary to under-a-probe CpGs (“YG” in the BCD sequence indicates no assumption of the concordant methylation with the interrogated dinucleotide)
