Introduction:
This study was carried out to evaluate PCR-based method for detection of DNA in goat milk. It utilized primers targeting the mitochondrial cytochrome -b (mtcyt-b) gene, which was used as a target DNA for PCR amplification.
Methods:
For the specific identification of goat mtcyt-b gene, pair of primers (GSL1, GSR2), were used, which produced a 428 base pair (bp) PCR product from milk samples as well as from peripheral blood. Amplification products were visualized on ethidium bromide-stained agarose gels.
Results And Discussion:
Amplification products were not detected when the PCR was applied to DNA from animal species including cattle, sheep, swine, camel, deer, horse, donkey, and human, which indicates that the 2 pairs of primers are specific for goat.
Conclusion:
DNA can be extracted from goat milk and would be advantageous in the variety of application such as species identification in milk and milk.
