Protein A/G

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.
The 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.

Example of applications:

• specific and sterically oriented bond of antibodies
• highest specificity and capacity
• retains antibody activity and orients antibody for maximum binding
• generally not suitable for sandwich ELISA assays

• 96-well microplates, solid or with 12 removable 8-well strips
• PCR 8 strip tubes
• PCR plates

The coated products show a CV% less than 5.

The coated products, if unopened, are stable at 2-8°C until the expiration date printed on the label. If opened, store in closed pouch with desiccant and use within the expiration date.

Product specifications for microplates

Recombinant Protein A/G (M.W. 50.4 kDa) is a fusion protein between Protein A and Protein G. The Protein A portion is from Staphylococcus aureus segments E, D, A, B and C and the Protein G portion is from Streptococcus sp. segments C1 and C3, expressed in E. coli. Protein A/G is coated using 200 µl/well. The strips are post-coated (blocked) for low non specific binding and long-term stability.

Product specifications for PCR 8 strip tubes and plates

Recombinant Protein A/G (M.W. 50.4 kDa) is a fusion protein between Protein A and Protein G. The Protein A portion is from Staphylococcus aureus segments E, D, A, B and C and the Protein G portion is from Streptococcus sp. segments C1 and C3, expressed in E. coli. Protein A/G is coated using 100 µl/tube. The PCR 8 strip tubes and plates are post-coated (blocked) for low non specific binding and long-term stability.
