中文摘要: 在碱性条件下用米糠多糖与三氯化铁制备米糠多糖铁(RBPIC)。理化试验表明米糠多糖与三氯化铁生成了稳定的RBPIC,RBPIC在pH4.1~12.6的条件下可以稳定存在,RBPIC中铁含量为18.41%;通过紫外-可见吸收光谱研究了RBPIC与ctDNA的相互作用,结果表明RBPIC与ctDNA存在明显的相互作用,结合常数为7.27×106L/mol;琼脂糖凝胶电泳实验表明BRPIC/DNA可以有效促进DNA凝聚。
Abstract:Rice bran polysaccharide iron complex (RBPIC)was prepared with rice bran polysaccharides and ferric iron at alkaline conditions.RBPIC was stable at pH 4.1-12.6 and the iron content in RBPIC was 18.41%.The interaction between ctDNA and RBPIC was studied by UV-vis absorption spectra.The results showed that the interaction between ctDNA and RBPIC was obvious,and the binding constant was 7.27×106L/mol.
