Synthetic oligosaccharides related to group B streptococcal polysaccharides. 3. Synthesis of oligosaccharides corresponding to the common polysaccharide antigen of group B streptococci
Immunoadsorbent combinations for the detection and diagnosis of group B streptococcus polysaccharide antigen, comprising an insoluble carrier, a capture agent having an affinity for specifically binding to the trirhamnose epitope of group B streptococcus antigen and having the formula α-L-Rhap(1->2)-α-L-Rhap(1->2)α-Rhap-1- wherein Rhap is rhamnose, and an antigen marker agent having an affinity for binding to monorhamnose epitope of group B streptococcus polysaccharide antigen of formula α-L-Rhap-1- when the group B streptococcus polysaccharide is bound to the carrier. An immunoassay method test kit and polyclonal antibody are also described.
用于检测和诊断B群链球菌多糖抗原的免疫吸附组合物,包括不溶性载体、与B群链球菌抗原的三鼠李糖表位特异性结合且具有式α-L-Rhap(1->2)-α-L-Rhap(1->2)α-Rhap-1-的捕获剂(其中Rhap为鼠李糖)和与式α-L-Rhap-1-的B群链球菌多糖抗原的单鼠李糖表位特异性结合的抗原标记剂、和一种抗原标记剂,当 B 群链球菌多糖与载体结合时,该标记剂与式 α-L-Rhap-1- 的 B 群链球菌多糖抗原的单鼠李糖表位具有亲和力。此外,还介绍了一种免疫测定法检测试剂盒和多克隆抗体。

(EN) Immunoadsorbent combinations for the detection and diagnosis of group B streptococcus polysaccharide antigen, comprising an insoluble carrier, a capture agent having an affinity for specifically binding to the trirhamnose epitope of group B streptococcus antigen and having the formula $g(a)-L-Rhap(1->2)-$g(a)-L-Rhap(1->2)$g(a)-Rhap-1- wherein Rhap is rhamnose, and an antigen marker agent having an affinity for binding to monorhamnose epitope of group B streptococcus polysaccharide antigen of formula $g(a)-L-Rhap-1- when the group B streptococcus polysaccharide is bound to the carrier. An immunoassay method test kit and polyclonal antibody are also described.(FR) Combinaisons immunoadsorbantes pour la détection et le diagnostique de l'antigène polysaccharidique du streptocoque du groupe B, comprenant: un excipient insoluble, un agent de capture possédant une affinité pour se lier spécifiquement l'épitode de trirhamnose de l'antigène du streptocoque du groupe B et de formule $g(a)-L-Rhap(1->2)-$g(a)-L-Rhap(1->2)$g(a)-Rhap-1- dans laquelle Rhap représente le rhamnose, un agent de marquage d'antigène ayant une affinité pour se lier à l'épitode de monorhamnose de l'antigène polysaccharidique du streptocoque du type B de formule $g(a)-L-Rhap-1- quand le polysaccharide du streptocoque du groupe B est lié à l'excipient. On décrit également une trousse de test pour le procédé de dosage immunologique ainsi qu'un anticorps polyclonal.
