General description

IgG antibody subtype is the most abundant of serum immunoglobulins of the immune system. It is secreted by B cells and is found in blood and extracellular fluids.

Specificity

The antiserum shows a single arc of precipitation versus bovine serum and bovine IgG by immunoelectrophoresis (IEP). This antiserum has not been assayed for interspecies cross reactivity.

Application

Anti-Bovine IgG (whole molecule) antibody produced in goat has been used in:
  • quantitative precipitation assays and in various immunosensor methods to detect bovine IgG in serum and milk
  • immuno-reaction assay
  • indirect sandwich enzyme linked immunosorbent assay (ELISA)
It has also been used in immuno-reaction assay.

Biochem/physiol Actions

IgG antibody subtype is the most abundant of serum immunoglobulins of the immune system. It is secreted by B cells and is found in blood and extracellular fluids and provides protection from infections caused by bacteria, fungi and viruses. Maternal IgG is transferred to fetus through the placenta that is vital for immune defense of the neonate against infections.

Physical form

Supplied as a liquid with 0.1% sodium azide (see MSDS) as a preservative.

Preparation Note

treated to remove lipoproteins

Storage and Stability

For continuous use, store at 0-5 °C. For extended storage, solution may be frozen in working aliquots. Repeated freezing and thawing is not recommended. Storage in "frost-free" is not recommended. If slight turbidity occurs upon prolonged storage, clarify by centrifugation before use.

Of the five immunoglobulin isotypes, immunoglobulin G (IgG) is most abundant in human serum. The four subclasses, IgG1, IgG2, IgG3, and IgG4, which are highly conserved, differ in their constant region, particularly in their hinges and upper CH2 domains. These
