PolysacDB ID1358
Carbohydrate NameLipopolysaccharide   (Drugpedia)
Carbohydrate ClassLipopolysaccharide
MicrobeChlamydia trachomatis serotype E   (NCBI Taxonomy)   (Drugpedia)
Basic StructureThe LPS is composed of the pentasaccharide bisphosphate αKdo-(2-8)-αKdo-(2-->4)-αKdo-(2-6)-βGlcN-4P-(1-->6) αGlcN-1P (Kdo is 3-deoxy-α-d-manno-oct-2-ulosonic acid)
BCSDB Structure2405
Proposed functionsLPS is most unusual constituents of outer membrane. It plays important role in host defence avoidance. LPS contributes to the negative charge of the bacterial surface. Lipid A is often toxic and act as endotoxin
Antigenic Nature used to produce antibodiesElementary bodies of Chlamydia trachomatis serotype E
Carrier NameNil
Conjugation MethodNil
AntibodiesMab EV1-H1
Antibody type and classIgG2a
Assay SystemIFT assay, ELISA
Cross-reactivityThis antibody cross-reacted with Salmonella Minnesota LPS and Chlamydia psittaci
Proposed epitopesThe epitope cosisted of a trisaccharide of a-3-deoxy-D-manno-2-octulosonic acid (KDO)
IEDB Epitope76828
Proposed UtilityThis Mab can be used in the epitope characterization of Chlamydial LPS
