GenScript 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. 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 human IgG/ml settled resin.
The binding capacity will
vary depending on several factors such as target antibody, flow rate etc. Table
1 lists the characteristics of Protein A Resin.

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.

GenScript’s Protein A Resin FF is an affinity chromatography media designed for easy, one-step purification of classes, subclasses and fragments of immunoglobulins from biological fluids and from cell culture media. Protein A Resin FF can also be used for immunoprecipitation of proteins, protein complexes or antigens.The recombinant protein A ligand is coupled to 4% highly cross-linked agarose. The coupling is optimized to have a high binding capacity for immunoglobulins. The static binding capacity of Protein A Resin FF is greater than 40 mg rabbit IgG/ ml settled resin. The dynamic binding capacity will vary depending on several factors such as target antibody, flow rate, etc. Table 1 lists the characteristics of Protein A Resin FF.

Protein A, a bacterial cell wall protein isolated from Staphylococcus aureus, binds to mammalian IgGs mainly at their Fc region.

Characteristics

Column compatibility

The 5 mL and 1 mL columns are compatible with ÄKTA™ chromatography systems. Additional adaptors may be needed for other systems. The optimal flow rate is 1 mL/min for the 1 mL column, and 5 mL/min for the 5 mL column. For preserving the column integrity, please do not exceed a flow rate of 4 mL/min for the 1 mL column and 15 mL/min for the 5 mL column (The mobile phase of the test is aqueous buffers at room temperature and the alarm pressure is 0.3 MPa).

Protein G, a cell surface protein of group G streptococci, is a Type III Fc receptor that binds to the Fc region of IgG by a non-immune mechanism similar to that of protein A from Staphylococcus aureus. This product contains three IgG binding domains, but its albumin-binding region has been removed. Additionally, His-tag and cysteine have been added to N- and C-termini, respectively, to facilitate purification and conjugation. This does not affect the protein’s ability to bind to IgG.

Description:

GenScript Protein G Resin is an affinity chromatography medium designed for easy, one-step purification of classes, subclasses and fragments of immunoglobulins from biological fluids and cell culture media. The recombinant protein G ligand is coupled to 4% highly cross-linked agarose. The static binding capacity of Protein G Resin is over 20 mg sheep IgG/ml settled resin. The dynamic binding capacity will vary depending on several factors such as target antibody, flow rate etc.

Protein G, a bacterial cell wall protein isolated from group G Streptococci, binds to mammalian IgGs mainly through Fc regions. Native protein G has 3 IgG binding domains and also sites for albumin and cell-surface binding. The latter have been eliminated from recombinant protein G to reduce nonspecific binding. Although protein G has very similar tertiary structures to protein A, their amino acid compositions differ significantly, resulting in different binding characteristics. Protein G can be used for purification of mammalian monoclonal and polyclonal IgGs that do not bind well to protein A. Protein G has greater affinity than protein A for most mammalian IgGs, especially for certain subclasses including human IgG3, mouse IgG1 and rat IgG2a. Unlike protein A, protein G does not bind to human IgM, IgD and IgA.
