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