It is intended to provide novel lipopolysaccharide adsorbents (bacteriotoxin adsorbents) which can be easily synthesized and modified into various analogous structures and are usable in adsorbing various lipopolysaccharides and a method of screening the same. A method of screening a bacteriotoxin adsorbent characterized by performing a binding assay with a peptide library with the use of a lipid A radioisotope-labeled preparation wherein a radioisotope has been introduced into a phosphonoxyethyl derivative of biosynthetic precursor type lipid A or Escherichia coli type lipid A; and bacteriotoxin adsorbents comprising a specific peptide library which are found out by the above screening method.
本发明的目的是提供新型脂
多糖吸附剂(细菌毒素吸附剂),这种吸附剂可以很容易地合成和修饰成各种类似结构,并可用于吸附各种脂
多糖,同时还提供一种筛选这种吸附剂的方法。一种筛选细菌毒素吸附剂的方法,其特征在于使用脂质 A 放射性同位素标记制剂与肽库进行结合试验,其中放射性同位素已被引入
生物合成前体型脂质 A 或大肠杆菌型脂质 A 的膦酰氧乙基衍
生物中;以及由通过上述筛选方法发现的特定肽库组成的细菌毒素吸附剂。
