Porcine-specific Primer based on Cytochrome B by Real-Time Polymerase Chain Reaction Method for Identification in Raw Meat

Pork is a type of meat that is often used for counterfeiting products with a composition of beef. This counterfeiting can provide large profits to producers, given the price of pork is far below the price of beef. So we need specific methods to ensure the halal product. The purpose of this study was to obtain a method for identification of pork using real-time PCR instruments. The validation parameters of the PCR realtime method include sensitivity test, linearity test, determination of detection limit and repeatability test. Specific pig primers designed with the NCBI and Primer-BLAST software (5 'CGGAACAGACCTCGTAGAATG 3' (forward) and 5 'GGTAATGATGAATGGCAGGATAAAG 3' (reverse) can amplify pig mitochondrial DNA Cytochrome with annealing temperature of 53.20C. Primary specificity is shown by Melting Curve Analysis (MCA) characterized by the appearance of a peak at the melting peak. Specificity testing was done on 4 DNA isolates of fresh meat (pork, chicken, beef, dog) and negative control. The results of the sensitivity test on fresh meat produced an efficiency value (E) of 417.4% and an R-value of 0.908. In the repeatability test, the Coefficient Variation (CV) value of fresh dog meat DNA isolates concentration of 50 ng / μL was 0.57%.
