By using single-strand conformation polymorphism (SSCP) analysis of three amplicons of the cytochrome b gene obtained by the polymerase chain reaction (PCR) it was possible to differentiate between various species of tunas and bonitos processed as canned fish. Four different techniques were used to produce single-strand DNA (ssDNA): (i) Denaturation of double-strand DNA (dsDNA) by formamide and alkali, (ii) two-step asymmetrical PCR, (iii) one-step asymmetrical PCR, and (iv) exonuclease digestion of the phosphorylated strand of dsDNA. The technique rendering optimal results depended on the type of amplicon (i.e. the sequence).
