Altogether Better

Alto combines the data quality of gold-standard SPR with the ease of use and speed of BLI

Leading researchers are choosing Alto

Both Alto and BLI are label-free biosensor technologies but only Alto delivers publication-grade kinetic data on even the most complex, multivalent biologics — without sacrificing ease-of-use.

  • Alto’s SPR sensors are located inside of a disposable microfluidic cartridge, and nanoliter sized droplets containing the various reagents and samples are brought to the sensor surface using a technology called digital microfluidics. This gives researchers reproducible, quantitative data they can act on with confidence.
  • BLI uses biolayer interferometry to measure the binding of a molecule in a well plate to a molecule immobilized on a biosensor probe, known as a “dip and read” measurement. This is useful for only quick yes/no answers but in biologics development, Alto takes research one step further by showing kinetic strength, stability, and mechanism.

Alto’s unique, patented integration of SPR sensors and microfluidics allows the ease of use and crude sample compatibility of BLI to be matched with the data quality of traditional SPR. Below is a more in-depth comparison of how Alto stacks up against traditional BLI instruments:

Alto provides the confidence behind every kinetic curve

BLI data quality can suffer due to:

  • Open well plates leading to evaporation
  • High ligand densities and inadequate mixing leading to mass transport and rebinding
  • Low sensitivity restricting molecular weights and fit accuracy

Alto overcomes these issues:

  • Closed cartridge with no evaporation
  • Microfluidic mixing and solution refresh to eliminate MTL and rebinding
  • Highly sensitive SPR probes expanding applications and improving fit accuracy

Alto saves labs up to $150,000/year

Alto’s digital microfluidics requires 50-100x less sample, combined with its cost-effective cartridges produced using high-volume manufacturing, means that for a typical year of usage, you can save up to 98% on your reagent/sample costs.
