The human placental immunoglobulin G receptor and immunoglobulin G transport

American Journal of Obstetrics and Gynecology, 1994
The 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

2021
Alternative 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 ...

Secretory immunoglobulin A and immunoglobulin G in horse saliva

Veterinary Immunology and Immunopathology, 2016
This study aimed to increase the knowledge on salivary antibodies in the horse since these constitute an important part of the immune defence of the oral cavity. For that purpose assays to detect horse immunoglobulin A (IgA) including secretory IgA (SIgA) were set up and the molecular weights of different components of the horse IgA system were ...

Immunoglobulin G Subclass Deficiencies

International Archives of Allergy and Applied Immunology, 2009
Low 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.

Immunoglobulin G in the Rabbit Cornea

Archives of Ophthalmology, 1969
Immunoglobulin G was detected by the fluorescent antibody technique in the corneas of six rabbits. It was present throughout the stroma and was not present in the epithelium, in Descemet's membrane, or in the endothelium.

Concanavalin A Reaction with Human Normal Immunoglobulin G and Myeloma Immunoglobulin G

Science, 1967
Concanavalin A precipitated less than 5 percent of immunoglobulin G from human serum. It reacted with all of 42 myeloma serums of the immunoglobulin G type tested, but no more than approximately 50 percent of the total myeloma protein was ever precipitated.

The carbohydrate composition of immunoglobulins G

Biochimica et Biophysica Acta (BBA) - General Subjects, 1971
Abstract Immunoglobulin G from human, horse, sheep, pig, cow, chicken, rabbit and dog blood serum was analyzed for its carbohydrate composition by gas chromatography, using alditol acetate derivatives of sugars released by acid hydrolysis. Fucose, mannose, galactose, glucosamine and sialic acid were present in IgG of all species studied.

Fragmentation of Immunoglobulin G

Current Protocols in Immunology, 1997
AbstractThis unit describes procedures for fragmentation of IgG to the monovalent Fab fragment using papain digestion, and to the bivalent F(ab′)2 fragment by pepsin digestion. Alternative methods of fragmentation to F(ab′)2 include use of papain that is preactivated with cysteine and use of the enzyme ficin.

Significance of immunoglobulin G subclasses

The American Journal of Medicine, 1984
IgG 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 ...
