Opis ogólny

IgG consists of four isotypes IgG1, IgG2, IgG3 and IgG4. It contains 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 connected by inter-chain disulfide bonds.

Zastosowanie

Purified IgG may be used as a reference antigen, standard, blocking agent or coating protein in a variety of immunoassays including ELISA, dot immunobinding, Western immunoblotting, immunodiffusion, immunoprecipitation and immunoelectrophoresis. Other applications include starting materials for the preparation of immunogens and solid-phase immunoadsorbents.

Działania biochem./fizjol.

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.
IgG mediates transplacental transport and participates in the secondary immune response. IgG activates the classical pathway of the complement system. It neutralizes virus particles and toxins. IgG plays a key role in antibody dependent cell-mediated cytotoxicity (ADCC) and phagocytosis. It might be linked to allergy. It has the longest serum half life.

Komentarz do analizy

Protein concentration should be determined after reconstitution by absorbance at 280 nm (E1%/280 = 14).

Previously, our laboratory demonstrated that a deregulated E2F5/p38/SMAD3 axis was associated with uncontrolled cellular proliferation in prostate cancer (PCa). Here, we investigate the role of E2F5 in PCa in further details. RNAi-mediated E2F5 knockdown and pathway-focused gene expression profiling in

Hyperlipidaemia accompanies chronic renal disease either as a consequence of the renal dysfunction or as part of generalized metabolic derangements. Under both situations, the lipid profile is characterized by accumulation of triglyceride-rich lipoproteins (TGRLs). This lipid profile is recognized as
