The detection of antibodies in sera of T. gondii-infected mice was done by ELISA using peroxidase-conjugated anti-mouse polyvalent immunoglobulin antibody as the secondary. Relative binding affinities for specific Mabs were determined by an inhibition ELISA using peroxidase-conjugated goat anti-mouse polyvalent antibody diluted 1:10,000 in PBST and incubated for 1 hour at 21-23°C.
Immunoglobulins are proteins produced by B cells in response to antigen and regulate response to bacteria, and viruses. IgG is known to regulate complement fixation and placental transport. IgA has a crucial role in mucosal immunity as it restricts pathogens from entering the mucosal membrane. IgM is the largest antibody having a pentameric structure which modulates polyreactivity and removes apoptotic cells,,. Goat anti-mouse polyvalent immunoglobulins (G,A,M)-peroxidase antibody binds to mouse IgG, IgA and IgM.
