Evaluation of multiplex PCR assay sensitivity for universal, cow, donkey and pork in cooked labortaty prepared samples; M: Marker 100-bp. NC: Negative control (reagents with primers without DNAs); Eu: Eukaryotic DNA positive control. (1) 24%, (2) 12%, (3) 6%, (4) 3%, (5) 1.5%, (6) 0.75%, (7) 0.05% (8) 0.005% (9) 0%.
Evaluation of multiplex PCR assay validity was performed on cow, donkey and pork in cooked labortaty prepared samples. M, Marker 100-bp; NC, Negative control (reagents with primers without DNAs).
Adulteration in commercial food samples at RYK district (A), Multan district (B) and Bahawalpur district (C).
100bp: Ladder, NC: Negative Control (Everything without primer of cow), Cow (Positive Control), Universal primer (99bp), Donkey (184bp), Cow (271bp), Pork (459bp). M1; Multiplex PCR 1, M2; Multiplex PCR 2 (Repeat).
