1HRM法检测p53基因外显子5-8的敏感性结果。野生型和突变型质粒混合后突变型所占的比例分别为2%、5%、10%、20%、50%和100%,分别显示不同颜色的熔解曲线。A:外显子5:蓝(wt),绿(2%),红(5%),棕(10%),黄(20%),灰(50%),紫(100%);B:外显子6:蓝(wt和2%),绿(5%),红(10%),紫(20%),黄(50%),灰(100%);C:外显子7:蓝(wt,2%和5%),绿(10%),灰(20%),紫(50%),红(100%);D:外显子8:红(wt),绿(2%),蓝(5%),黄(10%),紫(20%),灰(50%),棕(100%)
The exon 5-8 of p53 gene sensitive analysis by HRM. The mutation plasmid DNA was mixed with wild-type plasmid DNA to dilute the mutant allele to 2%, 5%, 10%, 20%, 50% and 100% of the total alleles. The melting curves of each dilution are shown in different color. A: exon 5: blue (wt), green (2%), red (5%), brown (10%), yellow (20%), grey (50%) and purple (100%); B: exon 6: blue (wt and 2%), green (5%), red (10%), purple (20%), yellow (50%) and grey (100%); C: exon 7: blue (wt, 2% and 5%), green (10%), grey (20%), purple (50%) and red (100%); D: exon 8: red (wt), green (2%), blue (5%), yellow (10%), purple (20%), grey (50%) and brown (100%)
