摘要
本文以小鼠骨髓细胞为材料,测定了人血红蛋白ε.基因5′端上游序列超敏感点Ⅱ(HSⅡ)中340bp,380bp两段DNA的结合白蛋.通过凝胶阻滞实验发现.340bpDNA有一较强的结合蛋白,而380dbpDNA有较弱的结合蛋白.
Using the cell of mouse marrow, we have observed the binding protein of 340bp DNA and 380bp DNA of the DNase superhypersensities site Ⅱin the up-stream to 5' -ε gene of human globin. With the gel retardation assay,we found that there was a protein which could be bound to 340bp DNA strongly and a protein which to 380bp DNA weakly.
