[edit] Carbohydrate Class
Lipopolysaccharide
[edit] Source Microbe
Pasteurella haemolytica serotype 1
[edit] Basic Structure
LPS molecule is composed of three regions consisting of lipid A, core oligosaccharides, and O-antigen polysaccharides. The O-antigen part consists of the following residues : -3)-β-D-Galp-(1-->3)-β-D-GalpNAc-(1-->4)-β-D-Galp-(1-. The core oligosaccharide part consists of the following residues : β-D-Galp-(1-->7)-D-gro-α-D-manHepp-(1-->6)-D-gro-α-D-manHepp-(1-->6)-β-D-Glcp-(1-->4)-L-gro [branched to L-gro-α-D-manHepp-(1-->2)-L-gro-α-D-manHepp-(1-->3)] and [branched to α-D-Glcp-(1-->6)] -α-D-manHepp-(1--/lipid A
[edit] Proposed functions
LPS is well known for its biological activities, including modification of metabolic activity and phagocytic function, alteration of migration of neutrophils and macrophages, and mitogenesis of lymphocytes
[edit] Antigenic Nature used to produce antibodies
P. hemolytica extract
[edit] Carrier Name
nil
[edit] Conjugation Method
nil
[edit] Antibodies
Mab H6B5
[edit] Antibody type and class
IgG3
[edit] Assay System
ELISA, immunoblotting
[edit] Cross-reactivity
This MAb had intense cross-reactivity among P. haemolytica serotypes 1, 5, 6, 7, 8, and 12 and less reactivity with serotypes 4 and 14 but did not react with LPS from any other gram negative bacteria tested
[edit] Proposed epitopes
N/A
[edit] Proposed Utility
This MAb to the LPS of P. haemolytica could be used to help further characterize the role of LPS in the pneumonic pasteurellosis disease process, including common binding sites and epitopes within the LPS molecule. It could be used in a screening kit, such as latex bead agglutination, to rapidly determine the presence of P. haemolytica in pneumonic lesions
