Protein G Coated Surfaces

The Biomat product is a 96 well coated microplate with recombinant Proein G and a protein to block non-specificbinding sites and to maintain stable activity.

Protein G specifically binds the Fc region of immunoglobulins of many mammalian species ( see table 1 ), with anorientation that allows the F(ab)2 binding sites to be freely available for efficient binding to epitope. When coated ontomicroplates, the Protein G 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 G ( mol. weight 26.1 kDa ) ,from Streptococcus sp., expressed in E.coli, is coated using 100μl/well. The strips are post-coated ( blocked ) for low non specific binding and long-term stability.

Binding capacity

The Biomat Protein G microplate shows a nominal binding capacity of ~ 5.3 pmol IgG/well


The Biomat Protein G microplate shows a sensitivity of 0.056 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, if unopened, are stable refrigerated until the expiration date printed on the label. If opened,store inclosed pouch with dessicant and use within the expiration date.
