The fused dominant peptide antigen 38 kD-ESAT6-CFP10 might serve as a serodiagnostic candidate antigen, and the double antigen sandwich ELISA using the fused antigen might be used to detect the tuberculosis and improve the specificity and sensitivity of diagnostic reagent.

该种抗原优势肽段融合抗原有望成为结核病血清学诊断的重要候选抗原，并且双抗原夹心ELISA方法有助于提高检测的特异性和敏感性。

objective to establish immunological methods specific for detecting antigens in different groups of monoclonal antibodies.methods indirect immnofluorescence assay was applied to identify specificity of the two groups of monoclonal antibodies prepared with crude antigen and recombinant antigen of aspergillus fumigatus,respectively.two different double monoclonal antibody sandwich elisa assays established with the two groups of antibodies were performed to detect antigents in the cell culture supermatants of 19 common species of aspergillus,penicillium marneffei,and 5 species of candidas.results the results of indirect immnofluorescence assay indicated that the monoclonal antibodies prepared with crude antigen of aspergillus fumigatus were specific for antigens in both clinical isolates and environmental isolates of aspergillus, whereas the other group of monoclonal antibodies was proved to be specific for aspergillus fumigatus of both clinical and environmental isolates.the elisa assay established with the crude antigen-specfic monoclonal antibodies could detect both of the clinical and environmental isolates of aspergllius, while the other assay could only detect aspergillus fumigatus of both clinical and environmental isolates.and no cross reaction with the cell culture of penialllium marneffei and candidas was observed with the two methods.conclusion the elisa assays can detect both of the clinical and environmental isolates of aspergillus,and differentiate aspergillus fumigatus from other species of aspergillus.

目的 用2组曲霉单克隆抗体建立特异性识别不同种类曲霉抗原的检测方法。方法采用天然烟曲霉抗原免疫，获得广谱针对曲霉抗原的单克隆抗体；采用重组烟曲霉抗原获得特异性针对烟曲霉抗原的单克隆抗体，用间接免疫荧光鉴定，并分别建立2种双抗体夹心elisa法，对19种常见的环境和临床分离曲霉株、马尔尼菲氏青霉菌及念珠菌培养液进行检测。结果间接免疫荧光显示，用天然烟曲霉抗原免疫获得的单克隆抗体(mabs-1)可广谱识别多种曲霉分离株，而重组烟曲霉抗原获得的单克降抗体(mabs-2)仅能特异性结合临床和环境分离的烟曲霉抗原。用mabs-1建立的双抗体夹心elisa法可检测19种常见曲霉株培养液；用特异性针对烟曲霉抗原单克降抗体(mabs-2)建立的双抗体夹心elisa法可特异性检测临床和环境分离株烟曲霉培养液；与其他曲霉株无交叉反应；2种双抗体夹心elisa法与马尔尼菲氏青霉菌及念珠菌培养液均无交叉反应。

Coil O85 antigen contained 8 varieties of genes, including UDP-Nacetylglucosamine-2-epimerase gene (f1). UDP-galactopyranose mutase gene, glycosyl transferase genes (f3, f5, f6, f8), O-antigen transferase gene and O-antigen polymerase gene, in which two genes, wzx and wzy and 4 pairs of primers were identified to be specific to E.

发现8个开放阅读框架并确定功能，分别为：UDP-N-乙酰葡萄糖－2-异构酶基因，吡喃型UDP-半乳糖变位酶基因，糖基转移酶基因（orf3、orf5、orf6和orf8），O-抗原转运酶基因和O-抗原聚合酶基因。

complete antigen：完全抗原

完全抗原(complete antigen)简称抗原. 是一类既有免疫原性,又有免疫反应性的物质. 如大多数蛋白质、细菌、病毒、细菌外毒素等都是完全抗原. 半抗原(hapten)是只具有免疫反应性,而无免疫原性的物质,故又称不完全抗原. 半抗原与蛋白质载体结合后,
