The present invention relates to conjugates of oligosaccharides of formula 1, wherein R is a linker to a carrier protein and optionally comprises up to three further saccharides, 5 and which are useful for vaccination, methods of synthesis of such conjugates, antibodies against this antigen, hybridoma producing monoclonal antibodies against this antigen, assays using these antibodies for the detection of
B. anthracis
spores and kits comprising these antibodies, and a vaccine for the prevention of
B. anthracis
infection comprising the conjugates of oligosaccharides of formula 1. Monoclonal antibodies 10 according to the invention selectively bind to
B. anthracis
, but not to related bacteria such as
B. subtilis, B. cereus
and other bacteria of this group such as
B. thuringiensis
.
本发明涉及公式1的寡糖结合物,其中R是连接到载体蛋白质的连接物,可选地包含多达三个进一步的糖类,其用于疫苗接种,合成这种结合物的方法,针对这种抗原的抗体,产生针对这种抗原的单克隆抗体的杂交瘤,使用这些抗体进行B. anthracis孢子检测的测定和包含这些抗体的试剂盒,以及包含公式1的寡糖结合物的B. anthracis感染预防疫苗。根据本发明的单克隆抗体能够选择性地结合到B. anthracis,但不结合到相关细菌,例如B. subtilis、B. cereus和该组细菌的其他细菌,例如B. thuringiensis。
