[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
