ABSTRACT
We analyzed the sequence of vertebrate molecular marker genes, then we selected the mitochondrial DNA (mtDNA) 16S rRNA gene as marker gene. In order to detect four kinds of animal-derived ingredients, which including bovine, goat, pig and chicken. We utilized a pair of universal primers, designed four sets of species-specific microarray probes and two pairs of quality control probes. We optimized the PCR amplifications and hybridization conditions, therefore these four kinds of animal-derived ingredients could be rapid and accurate detected by this approach. The detection limits were all reaches 1 pg. We established the detection platform of these four kinds of animal-derived ingredients. This universal PCR-microarray assay provides a new method for the identification of animal-derived ingredients in the import-export field.
