ABSTRACT
Objective The present study demonstrates a novel,simple and cost-effective method for detecting known SNP genotyping by using ShineRoar probes.Methods The SNP of target genes detected by using the ShineRoar probes and melting curve analysis.Tumor necrosis factor receptor Ⅱ (TNFR Ⅱ) and apolipoprotein M (apoM) had been employed as target genes to describe the method in details.The PCR products of TNFR Ⅱ and apoM were collected and sequenced.Results The melting temperatures (TM) were significantly different between mutated genotypes and wild-type genotype.A biallelic SNP marker (T/ G) at position 196 in exon 6 of TNFR Ⅱ gene showed two melting valleys with the appropriate TMs at (52.84?0.75)℃ and (58.38?0.61)℃,respectively.For apoM T-778C,TMs of homozygous T genotype and C genotype were (42.55?0.73)℃ and (49.19?0.57)℃,respectively.Moreover,this genotyping method was validated by the DNA sequence analyses (Kappa=1,P=0.000).Conclusion It is concluded that this novel method is simple and economical and it is suitable for a large-scale genotyping screening.
