Description

General description

IgG is the main type of antibody in human serum, secreted by the B cells. It is found in blood. IgG consists of four polypeptide chains, made of two identical 50 kDa γ heavy (H) chains and two identical 25 kDa κ or λ light (L) chains, which are linked by inter-chain disulfide bonds. IgG contains four isotypes IgG1, IgG2, IgG3 and IgG4.

The antibody reacts with an epitope located on the heavy chain of goat IgG1 and IgG2.

Specificity

Monoclonal Anti-Goat/Sheep IgG recognizes an epitope located on the heavy chain of goat IgG1 and IgG2. The antibody shows strong cross-reactivity with sheep IgG and weak cross-reactivity with bovine IgG. No cross-reactivity is observed with IgG derived from human, guinea pig, rat, horse, dog, chicken, pig, mouse, rabbit, or cat.

Application

Monoclonal Anti-Goat/Sheep IgG antibody produced in mouse has been used in:
• enzyme linked immunosorbent assay (ELISA)
• immunoblotting
• immunoprecipitation
• immunoelectrophoresis

Physical form

The product is provided as ascites fluid with 0.1% sodium azide as preservative.

Storage and Stability

For continuous use, store at 2–8 °C for up to one month. For extended storage, solution may be frozen in working aliquots. Repeated freezing and thawing is not recommended. If slight turbidity occurs upon prolonged storage, clarify by centrifugation before use.

Biochem/physiol Actions

IgG stimulates the classical pathway of the complement system. It neutralizes virus particles and toxins. IgG plays a crucial role in antibody-dependent cell-mediated cytotoxicity (ADCC). IgG might be associated with allergy. It has the longest serum half life.
