A latex test for the detection of human IgG aggregates and IgG anti-IgG antibody
Immunochemistry, 1972Abstract Latex particles (0·2 μ Lytron, Monsanto) were used for the measurement of certain types of human IgG. At pH 8·4 agglutination of latex particles occurred in the presence of purified 7 S IgG anti-IgG antibody and also of a 13 s IgG aggregate isolated from the serum of a patient with polymyositis, polyarthritis and hyperviscosity syndrome.

To DGP-IgG or not? a comparison of TTG-IgA and DGP-IgG
Clinica Chimica Acta, 2022We assessed the diagnostic utility of deamidated gliadin peptide immunoglobulin G (DGP-IgG) in pediatric patients without immunoglobulin A deficiency who underwent tissue transglutaminase immunoglobulin A (TTG-IgA) screening and biopsy.Patients who had TTG-IgA performed in our laboratory had sample frozen over 1.5 y.

?????????????????? IgG ?????????????? ?? ???? ?????????????????????????? ????????????
2011A new method, which allows evaluation of the avidity of bivalent antibodies when they react with bivalent antigen, is suggested. The theory is based on the idea that was proposed by us earlier. That theory considered the relation between affinity constants for bi-molecular and mono-molecular reactions of the reagents, which either are connected or not ...

Diagnostic accuracy of IgG 4/IgG and IgG 4 in patients with IgG 4-related disease: a meta-analysis
Zeitschrift für RheumatologieThis study aimed to evaluate and compare the diagnostic performance of immunoglobulin G4/Immunoglobulin G (IgG 4/IgG) and immunoglobulin G4 (IgG 4) alone in identifying immunoglobulin G4-related disease (IgG 4-RD).A systematic review and meta-analysis were conducted using data from Medline, Embase, and the Cochrane Library from inception to November ...

Ultrastructural Study of Human IgG and IgG-IgM Crystalcryoglobulins
American Journal of Clinical Pathology, 1979Thirty human cryoglobulin precipitates obtained from 21 patients were fixed and examined by electron microscopy; following biochemical isolation and identification. This study showed that the fine structure of cryoprecipitates depends on the involved immunoglobulins and on their respective quantities.

Glycosylation, one of the most common post-translational modifications in mammalian cells, impacts many biological processes such as cell adhesion, proliferation and differentiation. As the most abundant glycoprotein in human serum, immunoglobulin G (IgG) plays a vital role in immune response and protection. There is a growing body of evidence suggests

The measurement of IgG anti-IgG antibody in rheumatoid arthritis
Journal of Immunological Methods, 1974Abstract Serum IgG anti-IgG antibody was measured in patients with rheumatoid arthritis and osteo-arthritis and in healthy young adults. The antibody was isolated by immunoadsorption and evaluated by titration with latex particles. After establishing the method's specificity for IgG anti-IgG, its reproducibility and a means for converting titer to ...

Maleylation of bovine colostral IgG and human serum IgG
Immunochemistry, 1972Abstract Bovine colostral and human serum IgG were maleylated to different degrees to test for the reversibility of the maleylation reaction and the utility of this reaction in the study of the quaternary structure of immunoglobulins. The exhaustively maleylated IgG preparations were reduced-alkylated and the subunits were separated by gel filtration

Demonstration that IgG memory is carried by IgG‐bearing cells
European Journal of Immunology, 1976AbstractMemory B cells which give rise to JgG antibody‐producing cells were generally assumed to be IgG‐bearing cells. However, recent studies indicating that very few IgG‐bearing cells exist in lymphoid tissue brought this assumption into question. In this study, we examined directly the question whether IgG‐bearing cells contain functional precursors

IgG-Anti-IgG Antibodies in Juvenile Chronic Arthritis
Scandinavian Journal of Rheumatology, 1985IgG antiglobulins were measured in 117 children with seronegative juvenile chronic arthritis (JCA). 100 had active disease, and these had significantly higher levels of IgG antiglobulins (mean 0.45 +/- 0.16 micrograms/ml) than the control group (mean 0.25 +/- 0.16 micrograms/ml (p less than 0.01]. The inactive group of patients had a mean of 0.14 +/- 0.
