IMMUNOASSAY FOR DETECTING GROUP B STREPTOCOCCUS

摘要

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 alpha -L-Rhap(1->2)- alpha -L-Rhap(1->2) alpha -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 alpha -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.
