利用人类c-Ha-ras-1基因中28bp顺序串联重复子作为一个探针研究DNA纹印。以质粒PET为载体制备这个探针。从日本人外周血样中获取高分子量DNA。用识别位点为4个碱基的限制性内切酶Hinf·I或Sau3AI消化上述DNA。我们观察了洗脱条件不强烈情况下的由
DNA blotting was investigated using a 28 bp tandem repeat in the human c-Ha-ras-1 gene as a probe. This probe was prepared using plasmid PET as a carrier. High-molecular-weight DNA is obtained from Japanese peripheral blood samples. The above DNA was digested with Hinf-I or Sau3AI, which has a 4-base recognition site. We observed the absence of strong elution conditions
