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.
Key Features
- Protein A/G surface: It binds 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
- specific and sterically oriented bond of antibodies
- purification and detection of mouse monoclonal IgG antibodies and for purification of macaque IgG
- highest specificity and capacity
- retains antibody activity and orients antibody for maximum binding
- generally not suitable for sandwich ELISA assays
- Blocking: Plates are pre blocked with standard proteic blocking (ELISA Blocking) or with non proteic blocking (BlockerWell)
- Low Fluorescence Polystyrene: Manufactured with pure high-quality polystyrene, minimizing background noise and improving optical clarity.
- Wells design: flat bottom.
- Multiple Formats: Available in breakable strip plates, non-breakable strip plates, and solid plates for flexibility in applications.
-
Colors: Available in clear, white, and black. Customizable upper rim colors upon request. Reduced Crosstalk: White and black plates minimize well-to-well light scatter, improving signal accuracy in luminescence and fluorescence assays. Uniform Optical Properties: Clear plates are ideal for spectrophotometric readings and imaging, providing consistent and accurate light transmission.
