XanTec sensor chips

XanTec (1) offers a wide range of sensor chips for most common surface plasmon resonance instruments. Complementary to the most common used surfaces, there is a wide range of interesting other surfaces like the Agarose, alginate or gelatin gel, protein A, biotin, poly-L-lysine or the disulfide modified linear polycarboxylate hydrogel. Each of the sensor chip surfaces is ready to use in the instrument of your choice.

The basic difference between Biacore's and the XanTec surface chemistry is a different adhesion promoter which results in a lower level of non specific interactions and a higher activity of the immobilized ligand. In contrast to the state of the art, which applies a hydrophobic SAM, the XanTec adhesion promoter is hydrophilic and at the molecular scale more homogeneous
