Dedicated to Research
surface plasmon resonance
KEI's Surface Plasmon Resonance Instruments are on the market since 1997. KEI stands for high quality yet cost effective instruments dedicated to the research market.
KEI's Surface Plasmon Resonance instruments used for analysis of biomolecular interactions in real time without labeling. KEI's systems also provide the possibility of simultaneous electrochemical measurement with a separate potentiostat / galvanostat.
Surface Plasmon Resonance (SPR) has become a standard
tool in life sciences and pharmaceutical research laboratories. The
study and characterisation of molecular interactions is essential to
explore the structure-function relationships of biomolecules and to aid
our understanding of biological systems in life sciences, like
antibody-antigen, ligand-receptor, protein-nucleic acid, cell adhesion
and drug development. With the option of electrochemistry, an extra tool
is available for the study of enzymes, ion channels, membrane proteins,
polymer layers, polymerisation and polymer-biomolecular interactions.
SPR
provides quantitative information, which can be used to determine
reaction kinetics and affinity constants for molecular interactions, as
well as the active concentration of biomolecules in solution. It also
provides qualitative information and allows small-molecule screening to
epitope mapping and complex assembly studies.
Why Choose KEI?
Unique benefits from Innovative design
KEI's SPR instruments boast an innovative design which unlike many of its competitors is not flow based. The analyte remains whirling on the sensor excited by the peristaltic pumps. Many of the advantages of using KEI's SPR instruments over those of the main competitors stem from this smart design:
