Protein A/G Coated - 96 well plates - 8 Well Breakable Strips on single well holding frame

Protein A/G Plates 96-Well Breakable Strip Plates: Composed of 12 breakable strips of 8 wells, these plates allow easy customization by breaking and repositioning strips or single wells as required.

Protein A/G Coated Plates provide an efficient alternative to traditional passive adsorption methods for immobilizing antibodies in ELISA assays. The surface of these plates is designed to bind a wide range of IgG species, including all subclasses of mouse IgG (except IgA, IgM, or serum albumin) and all subclasses of human IgG, as well as IgA, IgE, IgM, and IgD. Protein A/G contains four Fc-binding domains from Protein A and two from Protein G, offering versatility in binding different immunoglobulins. Unlike Protein A alone, Protein A/G has reduced pH dependency, while combining the beneficial properties of both Protein A and Protein G, making it a powerful tool for various immunoassays.

Protein A/G Coated Plates are pre-blocked in order to minimize any non-specific binding and to ensure long-term stability.

Protein A/G Coated Plates are available in clear, white, and black polystyrene in Breakable Strip, Strip and Solid format. They are suitable for ELISA, Luminescence, Fluorescence, and Chemiluminescent assays.

Background

Protein A/G Coated Surface provides an alternative to direct, passive adsorption methods for immobilizing antibodies for ELISA and other plates-based assay techniques.
Protein A/G Coated Surface is a surface that binds to most IgG species (in particular binds to all subclasses of mouse IgG excluding mouse IgA, IgM or serum albumin and to all subclasses human IgG), IgA, IgE, IgM and IgD.

Protein A/G includes four Fc binding domains from Protein A and two from Protein G making it a versatile tool. The binding dependency to pH of Protein A/G is lower than Protein A but has the additive properties of Protein A and G together.

Protein A/G binds to human IgG, IgA, IgM; it binds to all subclasses of mouse IgG excluding mouse IgA, IgM and serum albumin (see Table 1). When coated onto microplates, the Protein A/G can securely be used in purification and detection of mouse monoclonal IgG antibodies with no interference from IgA, IgM and serum albumin.
