Figure 2From: Association study in naturally infected helminth layers shows evidence for influence of interferon-gamma gene variants on Ascaridia galli worm burdenGenotyping of chicken IL4 haplotypes (SNP exon 1 - SNP intron 1) by PCR-RFLP analysis. PCR products from hens with different genotypes (1-5) digested with Taa I, separated by agarose gel electrophoresis and stained with ethidium bromide. 1 = G-G/G-G, 2 = G-G/A-G, 3 = G-G/G-C, 4 = G-C/G-C, 5 = G-C/A-G(554 bp fragment usually not completely digested in genotype 5). M: 100 bp DNA size marker. Left numbers: marker sizes in bp. Right numbers: DNA fragment sizes in bp.Back to article page
