WAVEsystem: bioanalytical instruments for drug discovery and life sciences

The Creoptix® WAVEsystem provides a breakthrough level of binding kinetics analysis by pushing the boundaries of affinity range and sample compatibility. The WAVE’s superior data quality, sample compatibility, and automated software enhance drug discovery and allow new R&D advances.

The Creoptix® WAVEsystem combines the unequaled high sensitivity of the WAVEsystem’s proprietary Grating-Coupled Interferometry (GCI) technology with the WAVEcontrol software for improved data analysis, and the unique design of the WAVEchips, non-clog microfluidic sensor chips to support a wide range of sample types and sizes.

For added convenience, the WAVEsystem includes a temperature-controlled autosampler that accommodates vials, two 96- or one 384-well plates. Overall, the technology provides an unprecedented platform for real-time label-free binding kinetics.

  • Reliable kinetics and binding affinities (KD) ranging from low pM to low mM for signals as low as 1 pg/mm2
  • Crude samples, harsh chemicals, and particles up to 1000 nm
  • Ultra-fast transition times of 150 ms with accurate off-rate determination up to 10 s-1
  • Superior signal-to-noise ratios (0.01 pg/mm2 at 1 Hz)
  • Investigate substantial ligand-to-analyte molecular weight ratios of up to >1000:1
  • Self-contained disposable cartridge and small footprint
  • Up to 120 hours of unattended operation

Advantages

The Creoptix® WAVEsystem is a revolutionary optical biosensor technology for real-time label-free binding kinetics that combines high sensitivity, crude sample resilience, and advanced software. With its unique Grating-Coupled Interferometry (GCI) technology and cutting-edge microfluidics, it is now feasible to obtain fresh data from challenging materials for unparalleled insight.

Label-free data like never seen before

The proprietary Grating-Coupled Interferometry (GCI) technology is housed within the WAVEsystem providing the sensitivity to operate with low immobilization levels and high ligand-to-analyte molecular weight (MW) ratios. In conjunction, the WAVEsystem includes a temperature-controlled autosampler that can handle two 48-vial racks, 96- or 384-well plates, or combinations thereof.

High sensitivity

The readout of the refractive index change is different in Grating-Coupled Interferometry (GCI) compared to Surface plasmon resonance (SPR). In SPR signals are rapidly attenuated and reduced to a limited number of interactions. In GCI the evanescent field travels along the entire waveguide, thus it can pick up signals from a more significant number of interactions, which results in better sensitivity.

Higher sensitivity and reliable kinetic analysis are made possible by this, as well as improved high signal-to-noise ratios, assessment of kinetics (ka, kd) and affinity (KD) from low pM to low mM, and from signals below 1 pg/mm2 (equal to <1 RU).

Large ligand-to-analyte molecular weight ratios

Sensitivity is frequently a barrier to accurate and consistent kinetic study of big drug targets and small molecule inhibitors. Large target-to-analyte molecular weight ratios provide a considerable barrier to standard label-free measurement and can significantly influence data quality.

The Creoptix® WAVEsystem is compatible with high ligand-to-analyte molecular weight ratios, offering excellent resolution and consistent kinetics at low immobilization levels for target-to-analyte molecular weight ratios of up to >1000:1. As a result, the sensitivity to precisely assess low-potency small molecules or fragments, or targets with low activity, is enhanced.

More signal, less noise

GCI generates an evanescent field that penetrates the bulk less deeply than SPR, reducing the disruption produced by changes in the bulk refractive index—this decrease in noise results in higher signal-to-noise ratios.

Robust readout

Instead of projecting a space-domain signal onto a CCD camera as with standard waveguide interferometry methods, the patented GCI technology generates an interference readout in the time domain and within the waveguide. Measuring refractive index changes on the sensor surface as time-resolved phase-shift signals gives a more robust readout regardless of temperature drifts or vibrations, translating to higher signal and temporal resolution.
