Gel stained with ethidium bromide showing the genotypes of (A) IL-1β-31, (B) IL1β -511 and (C) ILRN genes. (A) Lane 7: 100 bp DNA ladder; Lane 1, 5, 13, 14: IL1β-31 C/C genotype (345 and 574 bp); Lane 2, 3, 8, 9: IL1β-31 C/T genotype (266, 345 and 574 bp); Lane 4, 6, 10, 11, 12: IL1β-31 T/T genotype (266 and 574 bp). (B) Lane 7: 50 bp DNA ladder; Lane 1, 2, 4, 5, 6, 8, 9, 10: IL1β-511 C/T genotype (279 and 289 bp). Lane 3, 11, 13, 14: IL1β-511 C/C genotype (279 bp), and lane 12: IL1β-511 T/T genotype (289 bp). (C) Lane 8: 100 bp DNA ladder, Lane 5, 10: ILRN 2/4 (240 and 412 bp); lane 1-4, 6, 7, 9, 11-13: ILRN 4/4 (412 bp); lane 14: ILRN 4/5 (412 bp and 498 bp).
