Targeting CpG DNA to screen and isolate anti-sepsis fraction and monomers from traditional Chinese herbs using affinity biosensor technology.

细菌DNA/CpG DNA是脓毒症发病关键分子，阻止其结合受体被认为最有前景。本研究以CpG DNA为靶标，用亲和生物传感器技术从78种中药水提物中筛选抗CpG DNA成分。大黄（Radix et Rhizoma Rhei）水提物结合能力最高。经硅胶柱和HPLC分离，获得活性组分Fraction D。体外显示Fraction D高亲...
