Fig. 4From: Influence of dopaminergic system gene polymorphisms on mixed amphetamine-type stimulants and opioid dependence in Malaysian Malaysa PCR product for amplification using SLC6A2 primers. b PCR-RFLP result following digestion with BsrD1 restriction enzyme. Lane 1 shows a 100-bp DNA ladder. Lane 2 shows heterozygous C/T wild-mutant alleles with 189-, 241-, and 343-bp fragments. Lanes 3, 5, and 6 show homozygous wild type C/C with a 343-bp fragment. Lane 4 shows homozygous mutant T/T with 189- and 241-bp fragmentsBack to article page
