Figure 2b: A 3% agarose gel showing HinfI digested PCR products of the PON1-55 and PON1-192 polymorphisms. Lanes (1, 2, 6): showed 144 bp band of MM genotype of PON1-55 and 111and 77 bp of QR genotype of PON1-192. Lane (3, 5, 7): showed 144 bp band of MM genotype of PON1-55 and 111 bp of QQ genotype of PON1-192.Lane (4): showed 122 bp band of LL genotype of PON1-55 and 77 bp of RR genotype of PON1-192. M: Molecular weight marker (PhiX174 DNA/HaeIII digest)
