在过去10年中,已确定一类角皮蛋白和糖蛋白存在于多种寄生和自由生活的线虫中,这类分子的特性(称为“表面相关的”)是能与放射性标记物结合并可溶于水。由于这些特性,表面相关抗原是暴露于膜表面的蛋白成分,更重要的是,由于它们是可溶性的,故表面相关成分很可能是非结构性的,且可 Over the past 10 years, it has been established that a class of keratin and glycoproteins are present in a number of parasitic and freely living nematodes whose properties (called “surface-related”) are capable of binding to radioactive labels and Soluble in water. Because of these properties, surface-associated antigens are protein components that are exposed on the surface of the membrane, and more importantly, because they are soluble, surface-related components are likely to be unstructured and may
