Annealing temperatures (Ta) of oligonucleotide primers employed in RT-PCR are shown. The location of oligonucleotide primers spanning ghrelin exons are listed, while oligonucleotides spanning synthetic sequences (adapters and linkers) or genes other than Ghrl are denoted as N/A (not applicable). The novel extended exon 1 is denoted as 1*. All primers were synthesised by Proligo (Armidale, Australia).
