Maleimide Coated Surface offers a powerful instrument for binding biomolecules containing free sulfhydryl groups or reducible disulfide bonds that are difficult to coat onto polystyrene plates.

Maleimide Coated Surfaces offer a powerful instrument for binding biomolecules containing free sulfhydryl groups (e.g. peptides that contain a terminal cysteine or thiol containing haptens ), or reducible disulfide bonds that are difficult to coat onto polystyrene plates. These coated products are a very useful tool for assays requiring site-directed orientation of particular biomolecules especially during antibody production.

At pH 6.5-7.5 maleimide reacts with free sulfhydryl groups to yield stable bonds, while the reaction with amine becomes significant at pH > 7.5.

If sulfhydryl-containing peptides and proteins oxidize in solution and form disulfide bonds, they must be preventively reduced to free sulfhydryls for allowing interaction with maleimide.

Biomat Maleimide Coated Products

Maleimide Coated Surfaces main features

Biomat Maleimide Coated products have the following characteristics:

  • Ready to Use
  • Manufactured under ISO:9001 guidelines
  • All lots are tested for uniformity and reproducibility
  • Certificate of Quality is released for every lot
  • For Research Use Only

Also, Maleimide Coated Products ensures:

Uniformity

The Maleimide Coated Products  show a CV% less than 10 when used as a catcher of Glutathione Ethyl Ester Biotin Amide (BioGEE) in an ELISA format using streptavidin-HRP as detector and TMB as substrate

Storage and Stability

The Maleimide 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.
