2.2. Oligonucleotide primers
The oligonucleotide primers targeting mitochondria DNA
(mtDNA) regions cyt b, cytochrome oxsidase II (COII) and ATP6 were
used in conventional PCR assays (Table 1). All mtDNA primers were
synthesized and supplied from First Base Laboratories (Selangor,
MY). A commercial primer targeting mtDNA cyt b gene (cyt b biotinlabeled
oligonucleotide primers) for PCR-southern hybridization on
chip (Olipro™ PORCINE Gene Chip Kit) was supplied
