Figure 1From: Simultaneous identification of GSTP1 Ile105→Val105 and Ala114→Val114 substitutions using an amplification refractory mutation systempolymerase chain reactionassay: studies in patients with asthmaIllustration of the sites of primers and Bsm AI restriction endonuclease maps of the variant GSTP1, together with the banding patterns obtained from the ARMS assay for each genotype. Products gave fragments of 343, 322, 260 and 73 base pairs with Ile105/Ile105; 93, 250, 322, 260 and 73 base pairs with the Val105/Val105; and all six fragments in heterozygotes (Ile105/Val105). Base pair numbering according to Morrow et al [21].Back to article page
