[edit] Antibodies
Mab Z3
[edit] Antibody type and class
IgG2b
[edit] Assay System
dot-ELISA, immunoblotting, electron microscopy, Opsonization and phagocytic assay, Protection assay, Bacterial clearance test
[edit] Cross-reactivity
This Mab reacted only with reference strains and field isolates of S. suis serotypes 1,2 and 1/2
[edit] Proposed epitopes
Mab Z3 reacts specifically with the sialic acid moiety of the capsule, a common constituent of the polysaccharidic capsular material of the three capsular types
[edit] Proposed Utility
This Mab was able to stabilize the capsule as shown by electron microscopy. Purified mAb Z3 was shown to significantly increase the rate of phagocytosis of S. suis cells by porcine monocytes and to activate the clearance of bacteria from the circulation in experimentally infected mice. mAb Z3 only offered partial protection to mice challenged with a minimal lethal dose
