일반 설명
Protein A is a highly stable cell surface receptor produced by several strains of Staphylococcus aureus. This protein is capable of binding to the Fc portion of immunoglobulins, especially IgGs, from a large number of species. One protein A molecule has been shown to bind at least 2 molecules of IgG simultaneously. The IgG binding domain of Protein A consists of three anti-parallel alpha-helicies, the third of which is disrupted when the protein is complexed with the Fc region of the immunoglobulins. Protein A will bind the Fc portion of human IgG subclasses, IgM, IgA and IgE; and mouse IgG1 (weakly), IgG2a, and IgG2b. Protein A also associates with IgGs from other species, including monkey, rabbit, pig, guinea pig, dog, and cat.
Protein A is involved in regulating anti-tumor, toxic, and carcinogenic functions. In addition to acting as an immunomodulator, it also has antifungal and antiparasitic properties.

애플리케이션
Protein A may be conjugated with various reporter molecules such as fluorescent dyes (FITC), enzyme markers (peroxidase, beta-galactosidase, alkaline phosphatase), biotin, and colloidal gold without affecting the antibody binding site on the molecule. These conjugates may be used to detect immunoglobulins using immunochemical assays such as western blotting, immunohistochemistry, and ELISA. In addition, protein A may also be immobilized on a solid supports like agarose or acrylic beads for the purification of polyclonal or monoclonal immunoglobulins. It is also routinely used for immunoprecipitation assays. Furthermore, protein A has been used for affinity chromatography and SDS-PAGE assays.

Dopamine is a catecholamine neurotransmitter, which plays an important role in the regulation of T cell functions. In activated T cells from normal volunteers, stimulation of D(1) and D(2) dopamine receptors inhibit cell proliferation and cytokine secretion. However, there is

The gene encoding the fibronectin-binding protein (FNBP) from Staphylococcus aureus strain 8325-4 was isolated from a gene bank in pBR322. The original clone, containing a 6.5-kb insert, gave a functional product present in the periplasm of Escherichia coli. Analysis of

The diagnosis of lipopolysaccharide-responsive beige-like-anchor-protein (LRBA) deficiency currently relies on gene sequencing approaches that do not support a timely diagnosis and clinical management. We developed a rapid and sensitive test for clinical implementation based on the detection of LRBA protein
