Immunoglobulin G Subclass Deficiencies
International Archives of Allergy and Immunology, 1987Low levels of single or multiple serum immunoglobulin G (IgG) subclasses is a common finding among patients with increased susceptibility to infections. In this investigation we summarize data from studies of 503 subclass-deficient individuals. Low IgG2 levels was the most common deficiency among children, and boys were more often deficient than girls.

Purification of Immunoglobulin G
Current Protocols in Cell Biology, 1997AbstractWhile unpurified antibodies are suitable for a number of applications, purified antibodies are required for assays based on known concentration of antibody, for chemical modifications such as radiolabeling or conjugation with fluorochromes, or for structural modifications such as production of F(ab')2 or monvalent Fab fragments.

The human placental immunoglobulin G receptor and immunoglobulin G transport
American Journal of Obstetrics and Gynecology, 1994The objective of this study was to quantitatively determine an immunoglobulin G receptor, placental alkaline phosphatase, and its ligand immunoglobulin G in maternal and fetal blood and to study the transport capacity of the receptor.Venous blood samples from 66 term pregnant women and cord samples from their fetuses were obtained, together with the ...

Epigenetics of Immunoglobulin G Glycosylation
2021Alternative glycosylation of immunoglobulin G (IgG) affects its effector functions during the immune response. IgG glycosylation is altered in many diseases, but also during a healthy life of an individual. Currently, there is limited knowledge of factors that alter IgG glycosylation in the healthy state and factors involved in specific IgG ...

Immunoglobulin G Glycosylation in Diseases
2021Changes in immunoglobulin G (IgG) glycosylation pattern have been observed in a vast array of auto- and alloimmune, infectious, cardiometabolic, malignant, and other diseases. This chapter contains an updated catalog of over 140 studies within which IgG glycosylation analysis was performed in a disease setting.

Significance of immunoglobulin G subclasses
The American Journal of Medicine, 1984IgG subclasses differ from one another both immunochemically and functionally. An isolated absence of a certain specific subclass may or may not be associated with disease. However, an absence of serum IgG4 as measured by a sensitive radioimmunoassay is usually, if not always, associated with severe recurrent pyogenic infections, usually of the ...

Placental transport of immunoglobulin G
Vaccine, 2003Maternal antibodies transported across the placenta protect the newborn. Maternal immunoglobulin G (IgG) concentrations in fetal blood increase from early in the second trimester through term, most antibodies being acquired during the third trimester. IgG1 is the most efficiently transported subclass and IgG2 the least.
