ALTO - digital high‑throughput benchtop SPR system

The world’s first digital high‑throughput benchtop SPR system.

Description

Surface Plasmon Resonance Powered by Digital Microfluidics.

Alto is the world’s first SPR instrument to integrate digital microfluidics (DMF), artificial intelligence (AI), and nanotechnology to provide high quality, label-free interaction analysis. DMF technology enables all fluidics to be disposable, allowing for precise handling of 2uL sample volumes, crude sample compatibility and zero maintenance.

Alto’s compatibility with automation for both hardware and software provides
sample-in/answer-out data, industry leading throughput, and 24/7 runtime. Every aspect of Alto is designed with user-friendliness and accessibility in mind - from the flexible 16-channel design to the intuitive data analysis platform.

Alto is capable of supporting operation in GXP and 21 CFR Part 11 in compliance with regulatory demands.

Industry-Leading Data Quality
Minimize noise and dispersion; maximize sensitivity
The fastest rise times at <0.1s

High-Throughput Powered by Automation and AI
16 channels, intelligent assay design/optimization, automated serial dilutions
Fully compatible with plate & liquid-handling robots

Sample-Friendly
Only 2μL required for full kinetics
Analyze crude samples with ease

User-Friendly
Free of high-maintenance fluidic components and obsolete software

What is Digital Microfluidics?

DMF is a liquid-handling technology capable of accurately controlling and manipulating discrete nanodroplets with electricity on a standard microwell plate.

Why DMF?

DMF fluidic handling technology removes the need for any physical pumps, valves, or tubes and replaces them with a low cost disposable cartridge, providing higher data quality and less hands-on time.

How does SPR work with DMF?

We’ve integrated our proprietary localized surface plasmon resonance (LSPR) sensors into DMF cartridges – creating 16 independently addressable channels on a single cartridge.

Advantages of using DMF-powered SPR

Decoupling of flow rate and sensor position from dispersion, increasing data quality

500X less sample volume required— get full kinetics from a 2μL sample volume

Decoupling of interaction time from sample volume, increasing assay flexibility

Automated serial dilutions—reducing human error and saving time

ALTO Cartridges

Alto Cartridges have completely revolutionized the interaction of fluidics and sensors for SPR.

A Cartridge is a well-plate sized consumable that integrates reagent/sample storage, fluid handling, and sensor surfaces. Samples, buffers and reagents are contained in wells on the cartridge, and dispensed towards the sensor in software-controlled nanodroplets.

Precise volumes and automated serially diluted concentrations interface with a fiber optic sensor tip, manufactured with the same quality and consistency (<2% CV) as our existing localized SPR sensors.

Surface Chemistries

Carboxyl for any amine group using EDC/NHS coupling
NTA for histidine tagged targets
Streptavidin for biotin tagged targets
Biotin for streptavidin coupled targets
GST for GST tagged targets
Protein A for IgG based antibodies
Amine for any carboxyl group using EDC/NHS coupling
Liposome Binding (LIP) for liposomes/membrane proteins
Hydrophobic (MEM) for lipid monolayer
Thiol for thiol or maleimide tagged targets
Gold for non-functionalized and for custom surface chemistry development and targets with thiol groups

Alto Software Suite

Alto features an end-to-end software suite that is powered by AI, built directly into the instrument, and leverages the power of the cloud. Flexible and intelligent assay design and optimization enables efficient planning of experiments. Serial dilutions are fully automated and controlled by software, reducing hands-on time and human error. With cloud connectivity, real-time data and wizards will clearly communicate experiment progress and can be accessed by any licensed device connected to the internet.
