指纹图谱是一种以电泳图或杂交图对蛋白质或DNA的结构特征进行分析的方法。通常,指纹图谱是指蛋白质或DNA的酶解图谱。 在DNA指纹图谱分析中,大分子DNA经合适的限制性内切酶酶解,然后在凝胶介质中电泳,将酶解片段分离,所得分离图谱即为DNA指纹图谱。在人类,由于每个人的DNA指纹图谱各不相同(据估计, Fingerprinting is a method of analyzing the structural features of proteins or DNA by electrophoretic or hybridization. Fingerprinting generally refers to enzymatic digestion of proteins or DNA. In the DNA fingerprinting analysis, the macromolecular DNA is digested with suitable restriction enzymes and then electrophoresed in a gel medium to separate the enzymatic fragments. The resulting isolated chromatogram is a DNA fingerprinting. In humans, since each person’s DNA fingerprinting varies (it is estimated that,
