The capability of PCR-TTGE to detect meat species in mixed animal samples was investigated as a necessary step in developing a method where the identification will be performed matching on the "DNA barcode" zone the sequences of resolved PCR products obtained from a limited set of "universal" primers.

Abstract

The capability of PCR-TTGE to detect meat species in mixed animal samples was investigated as a necessary step in developing a method where the identification will be performed matching on the "DNA barcode" zone the sequences of resolved PCR products obtained from a limited set of "universal" primers. Exemplary mixtures from five important meat species were analyzed. At this stage more PCR reactions have to be applied on a sample but this should be easily improved using primers simultaneously (as a "cocktail") in a single reaction.

DNA barcoding
Un importante strumento per l'identificazione delle specie animali, l'iniziativa "DNA barcoding of life", è nata da una collaborazione internazionale con lo scopo di costruire un database contenente le sequenze di DNA di tutte le specie animali. L'identificazione viene fatta considerando principalmente una porzione del gene della citocromo c ossidasi subunità I. In questo lavoro sono stati analizzati i prodotti di PCR provenienti da cinque delle principali specie di animali da carne: bovino (Bos taurus), pollo (Gallus gallus), tacchino (Meleagris gallopavo), agnello (Ovis aries) e maiale (Sus domesticus).
