Genotyping analysis of IL-4-589C/T polymorphism using PCR-RFLP technique. PCR-RFLP assay for analyzing IL-4-589C/T polymorphism. PCR product was digested by AVA II restriction enzyme and visualized on 3% agarose gel. M: marker (50 bp ladder). Lanes 1, 4, 5, 6, 8, and 9 show CC homozygous (177 bp band, 18 bp is not seen); lanes 2, 3, and 7 show CT heterozygous (195 and 177 bp bands)
