Analysis of raw meats and fats of pigs using polymerase
chain reaction for Halal authentication
We employed a three step analysis to determine the
identity of meat and fat samples: (i) genomic and mt-
DNA isolation (ii) mt-DNA is subjected to PCR amplification
of the cyt b gene and (iii) the cyt b amplicon is
cut with RE to reveal the RE cutting pattern so that
the identity of the meat and fat source can be revealed.
Additionally, we wanted to determine if enough
DNA could be obtained from fats to carry out PCR amplification.
The quality of the extracted DNA from 25 mg of
meat and fat samples using the DNeasy Protocol for
animal tissue provided with the DNeasy Tissue Kit
(Qiagen) was examined by electrophoretic analysis
through a 1.2% agarose gel (Promega). A band of high
intensity appeared in the lanes (Fig. 1). This showed that
