^a Detection of (putative) nucleotide differences by array hybridization between clone 1 and 18f was initially based on the hybridization profile in Fig. (6).

^b Probe numbers are from Fig. (6) and represent the oligonucleotide probes whose sequence contains nucleotide change(s) between clone 1 and 18f when the clone 1 target sequence is identical to the probe sequence. Nucleotide changes were indentified (grey boxed) based on comparison of the clone 1 and 18f GenBank sequences (accession numbers in Fig. (1)) used to develop the HAV1Cb group 1 consensus probe set (Fig. 1). The probe nucleotide range numbering is defined by the 29-mer probe and corrected to 18f nucleotide numbering from Lemon et al. [²¹].

^c The nucleotide change and position between clone 1 and 18f as reported by Lemon et al. [²¹].

^d Probe 120 defines a 26 nucleotide base region of 18f due to the three-base GAT deletion.

^e This probe identified as a potential peak overlapping with the peak at probe 441.
