The world's first 3D biosensor surface for label-free biomolecular interaction analysis now offers surface chemistries for: carboxyl, streptavidin, benzaldehyde, NTA-Ni for His-tagged proteins, Protein A and Protein G for coupling antibodies.
San Diego, CA (PRWEB) February 8, 2010 -- Silicon Kinetics Inc., the pioneering life sciences tool company which introduced the world's first 3D biosensor surface for label-free biomolecular interaction analysis, announced the availability of three new surface chemistries: NTA-Ni, Protein A and Protein G.
Featuring biosensors with 3D nanoporous silicon chips, Silicon Kinetics SKi Pro™ is the world's only label-free biomolecular interaction analysis platform which allows high throughput ranking in multiwell plates and data-rich kinetic measurements in flow cells, all using the same reader instrument and the same surface chemistry. Available surface chemistries now include: carboxyl, streptavidin, benzaldehyde (a unique covalent surface which requires no activation step) and the newly introduced NTA-Ni for His-tagged proteins, Protein A and Protein G for coupling antibodies.
