  • a See Table 3 for the conditions of experiments A to E. *, Experiments included in training set.

  • b The scores given are from the weighted oligonucleotide calculation (see Materials and Methods). Values in parentheses are the numbers of signature oligonucleotides that registered positive. There were no NA-specific oligonucleotides that reacted with N4, N8, or N9 subtypes in BLASTn searches.
