Protein A Coated Surfaces

The Biomat product is a 96 well coated microplate with recombinant Protein A and a protein to block non-specific binding sites and to maintain stable activity.

Protein A specifically binds the Fc region of immunoglobulins of many mammalian species ( see table 1 ), with an orientation that allows the F(ab)2 binding sites to be freely available for efficient binding to epitope. When coated onto microplates, the Protein A can securely capture IgG applied directly or as antigen/antibody complexes.

Example of applications:

Product specifications

Individually pouched 96-well microplates, configured in 12 removable 8-well strips or solid plate

Recombinant Protein A ( mol. weight 38.9 kDa ) ,from Staphylococcus aureus subsp. Aureus, expressed in E.coli, is coated using 200 μl/well. The strips are post-coated ( blocked ) for low non specific binding and long-term stability.

Binding capacity

The Biomat Protein A microplate shows a nominal binding capacity of ~ 5 pmol IgG/well


The Biomat Protein A microplate shows a sensitivity of 0.113 ng/well of human IgG.

Microplates show a CV% less than 5 when used as a catcher of biotinylated human IgG in an ELISA format usingstreptavidin-HRP as detector and TMB as substrate.

Storage and Stability
The microplates, under the indicated storage conditions 2-8 °C, are stable until the expiration date printed on the label.If opened,store in closed pouch with dessicant and use within the expiration date.
