Figure 8: An example of species identification by standard PCR amplification using species-specific primer sequences cloned from RAPD gel. Genomic DNA of cattle, pigs, sheep and goats was used as temples and amplified with pig-specific primers by PCR. The species-specific bands on the agarose gel were present in pigs only. Control: amplified 18S ribosomal gene fragments. M: DNA ladder markers. |
