Protein G magnetic particles are a type of biomagnetic separation technology used for protein purification and analysis. These particles are coated with Protein G, an antibody-binding protein that can specifically bind to the constant region of immunoglobulins (IgGs). Because antibodies are often used in research and diagnostic applications, Protein G magnetic particles can be used to purify and isolate antibodies from complex mixtures such as cell lysates, serum, or ascites fluid. The magnetic properties of the particles allow for easy capture and separation by applying a magnetic field. https://www.cd-bioparticle...
