[1] Immunoglobulin G (IgG)

1985
Publisher Summary This chapter provides an overview of immunoglobulin G (IgG). IgG molecules consist of identical pairs of heavy (H) and light (L) chains (MW = 50,000 and 25,000, respectively) linked by disulfide bridges. A proteolytic enzyme (papain) splits IgG into three fragments which retain biological activity: two Fab (for antigen binding ...

Immunoglobulin G Glycosylation in Diseases

2021
Changes 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.

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.

Purification of Immunoglobulin G (IgG)

2003
Several immunological procedures can be successfully carried out using nonpurified antibodies, such as unfractionated antisera, or ascitic fluid/culture supernatant containing monoclonal antibodies (MAbs). However, a much "cleaner" result can often be obtained if some form of enrichment or isolation of immunoglobulin is employed.

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.

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.

Human Immunoglobulin G and Immunoglobulin G Subclasses: Biochemical, Genetic, and Clinical Aspects

Critical Reviews in Clinical Laboratory Sciences, 1989
Human IgG consists of two identical heavy (H) chains and two identical light (L) chains joined by interchain disulfide bridges. Heterogeneity in the amino acid sequences of the H and L polypeptides results in at least three types of IgG variants at the structural and genetic levels.

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 ...

Serum immunoglobulins and immunoglobulin G subclasses with recurrent wheezing

The Indian Journal of Pediatrics, 2000
In this study serum immunoglobulins (Ig) and IgG subclasses were measured in 42 patients (ranging 9 month-6 year) with recurrent wheezing and in 37 healthy children determined the relationship between serum Igs and recurrent wheezing. Patients were divided into two groups according to the age [9 month-2 year (n: 15), and 2-6 year (n: 27)].

Placental transport of immunoglobulin G

Vaccine, 2003
Maternal 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.
