When endotoxins extracted from enteric bacteria were mixed in the presence of sodium deoxycholate, and the bile salt was subsequently removed by dialysis or by extraction with ethanol, a new type of endotoxin was formed. The latter material was as biologically active as the original endotoxins and possessed a combination of antigenic determinants that were previously unique to each of the individual endotoxins in the mixture. This hybrid formation between endotoxins was detected by immunodiffusion and radioautography and by quantitative precipitation procedures.
当从肠道细菌中提取的内毒素在脱氧胆酸钠存在的情况下混合,随后通过透析或用乙醇萃取去除胆汁盐时,会形成一种新型内毒素。后一种物质与原始内毒素具有相同的生物活性,并具有混合物中每种单独内毒素以前特有的抗原决定簇组合。通过免疫扩散、放射自显影和定量沉淀程序检测到内毒素之间的这种杂交形成。
