Description

Protein G - 20nm gold conjugate is a complex formed by the conjugation of Protein G to 20 nm gold nanoparticles. Protein G is a cell wall protein derived from group G of Streptococcus. It can specifically bind to the Fc region of IgG from a variety of species and has better binding capacity to IgG than Protein A. When Protein G - 20nm gold conjugate is added to biological samples, target proteins or antigens can be detected and visualized. One of its main advantages is their high sensitivity and specificity in detecting target proteins or antigens in biological samples. In addition, the small size of the gold particles allows for precise localization of the target molecule, making it particularly useful in electron microscopy studies where high resolution and detail are required.

Applications

• Immunohistochemistry, immunocytochemistry, and electron microscopy. Protein G - 20nm gold conjugate is commonly used in immunohistochemistry, immunocytochemistry, and electron microscopy techniques to detect and localize specific proteins or antigens within cells or tissues.
• Protein purification. Protein G - 20nm gold conjugate can be used for the purification of antibodies or other proteins through affinity chromatography. The Protein G binds specifically to the Fc region of antibodies, allowing for easy isolation and purification of target proteins.
• Immunoassays. Protein G - 20nm gold conjugate can be used in various immunoassays, such as enzyme-linked immunosorbent assay (ELISA), Western blotting, and immunoprecipitation.

Storage

• Store undiluted in storage buffer at 2-8 °C. Stable for 4 months if stored as specified.
• It is important to note that storing conjugate at working dilution may result in performance loss.
