--Non-precipitating antibodies localized in the IgG,, IgGb and IgGc were isolated from serum of horses inoculated with DNP-HGG, with or without anti-DNP precipitins. The methods for isolation and purification of precipitating and non precipitating antibodies are described. The physicochemical characteristics and biological properties of precipitating and non-precipitating antibodies localized i...
Macromolecular albumin-IgG complexes have been isolated from human serum and characterized immunologically. These complexes are shown to be present in plasma also and appear to be normal constituents of blood. The complexes can be demonstrated in normal serum and plasma by immunoelectrophoresis and rocket immunoelectrophoresis, as well as by use of a two-step radioimmunologic binding test. The ...
The aim of this study was to evaluate the potential diagnostic usefulness of the full-length recombinant Toxoplasma gondii MAG1 protein by determining the levels of specific IgM and IgG antibodies in mouse and human sera obtained from individuals with acute and chronic toxoplasmosis. The obtained results revealed that IgG antibodies against MAG1 are a sensitive and specific marker of T. gondii ...
The global incidence of dengue has increased significantly in recent decades, resulting in a large public health burden in tropical and subtropical countries. Dengue rapid diagnostic tests (RDTs) can provide accurate, rapid accessible diagnosis for patient management and may be easily used by health workers in rural areas. However, in dengue-endemic areas, ambient temperatures are often higher ...
i mmunoglobulins, produced by plasma cells, are the effector arm of the humoral immune system [1]. Each immunoglobulin consists of two identical heavy chains (α, β, γ, δ or ε – all encoded by chromosome 14) and two identical light chains (either κ or λ, encoded by chromosome 2 and 22, respectively) [2]. The immunoglobulins have constant (C) regions (similar within the same isotype) and variable...
Local genital antibodies to the infecting strains of Neisseria gonorrhoeae were demonstrated by indirect immunofluorescence (binding antibody) and by their ability to inhibit the attachment of gonococci to epithelial cells (functional antibody). Both IgG and IgA classes of immunoglobulin were involved, and the IgA component were primarily of a secreting (11S) nature. The ability of local genita...
The IgG molecule, like all antibodies, is a glycoprotein, and with the discovery in 1959 that the rabbit IgG molecule could be split by the action of papain into two Fab (antigen-binding) and one Fc (crystallizable, complementand cell-binding) fragment, the major glycosylation site was found to lie within Fc (Porter, 1959). (The Fc fragment conists of the C-terminal half of each of the two ‘hea...
