【摘要】 将两株抗旋毛虫单克隆抗体（ＭｃＡｂ）杂交瘤细胞（Ｄ４，Ｅ２）所分泌的ＭｃＡｂ，经纯化后电泳分析，其重链分子质量为５５ｋｕ，轻链分子质量为２９ｋｕ，符合ＩｇＧ抗体的特点。两株ＭｃＡｂ与旋毛虫阳性猪血清所针对的旋毛虫抗原决定簇相同，都不与猪的其它寄生虫发生交叉反应，与抗原的相对亲和力Ｅ２＞Ｄ４，ＭｃＡｂ亲和层析纯化抗原的分子质量为４９ｋｕ，经免疫斑点染色证明为糖蛋白。更多还原

【Abstract】 The monoclonal antibodies (McAbs) against [WTBX]Trichinella spiralis secreted by two strains of hybridomas (D 4,E 2) were purified and analysed with electrophoresis, which revealed that the molecular masses of the heavy chain and the light chain were 55 ku and 29 ku respectively which was in accord with the trait of IgG. The two McAbs and the Trichinella spiralis postive pig’s serum aimed at the same antigenic determinant but no cross reaction with another parasites in swine occurred; the relative affinity with antigen of E 2 was stronger than that of D 4. The molecular mass of McAb affinity chromatography purified antigen was 49 ku. It was proved that the purified antigen was a glucoprotein by means of an immunity dot staining test.更多还原
