单克隆抗 山羊/绵羊 IgG，0.2ML，G2904-.2ML，Sigma

General description

抗体与位于山羊 IgG1 和 IgG2 重链上的表位反应。
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.

Application

Monoclonal Anti-Goat/Sheep IgG antibody produced in mouse has been used in:

• enzyme linked immunosorbent assay (ELISA)
• immunoblotting
• immunoprecipitation
• immunoelectrophoresis

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.
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.

Physical form

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