  • Target
    Reactivity
    Staphylococcus aureus
    Application
    Affinity Chromatography (AC), Purification (Purif)
    Purpose
    Protein A Resin is an affinity chromatography medium designed for easy, one-step purification of classes, subclasses and fragments of immunoglobulins from biological fluids and from cell culture media.
    Characteristics
    Protein A Resin can also be used for immunoprecipitation of proteins,protein complexes or antigens. The recombinant protein A ligand is coupled to 4% agarose. The coupling is optimized to give high binding capacity for immunoglobulins. The static binding capacity of Protein A Resin is greater than 20 mg rabbit IgG/ml settled resin. The dynamic binding capacity will vary depending on several factors such as target antibody, flow rate etc.

    Number of IgG binding sites per ligand: 5
    MW of ligand: Approximately 34 kDa
    PI of ligand: 5.17
    Degree of substitution: Approximately 2 mg protein A/ml settled resin
    Static binding capacity: >20 mg rabbit IgG/ml settled resin
    Matrix: spherical agarose, 4%
    Average particle size: 90 μm (45-165 μm)
    Bead Ligand
    Protein A
    Bead Matrix

    Background
    Protein A, a bacterial cell wall protein isolated from Staphylococcus aureus, binds to mammalian IgGs mainly through Fc regions. Native protein A has five IgG binding domains and many other domains with unknown functions. Recombinant protein A contains five high affinity IgG binding domains with other non-essential domains removed to reduce nonspecific binding. Since only the Fc region is involved in binding, the Fab region is available for binding antigens.
