用辣根过氧化物酶标记α-珠蛋白-3’－HVR探针检测同一个体的DNA，其所产生的DNA指纹图谱带随着酶解条件的变化而发生改变。由于谱带的改变，给亲子关系的同一认定带来了困难，尤其是多位点探针的检测。为了了解Hinfl和Hae皿两种酶在不同酶解时间和不同酶量的条件下对DNA指纹图 Horseradish peroxidase-labeled α-globin-3’-HVR probe was used to detect the DNA of the same individual, and the DNA fingerprinting bands produced by the enzyme were changed with the change of the enzymolysis conditions. Due to the change of the band, it is difficult to identify the same parent-child relationship, especially the detection of multi-site probes. In order to understand Hinfl and Hae dish two enzymes in different enzymatic hydrolysis time and different enzyme conditions on DNA fingerprinting
