Detect protein aggregation early with NanoSight Pro. Gain particle-level insight to improve stability, reduce risk, and accelerate biologics development.
Protein therapeutics, including recombinant proteins, enzymes, and peptide-based drugs, play a central role in modern medicine. From enzyme replacement therapies to advanced biologics, these molecules are engineered to deliver highly specific therapeutic effects. Their clinical success depends on maintaining precise structural integrity throughout development, manufacturing, and storage.
Unlike small molecules, protein-based therapeutics are inherently sensitive to their environment. Subtle changes in temperature, formulation conditions, or mechanical stress can disrupt molecular structure and trigger instability. These changes are often not immediately visible, yet they can have a profound impact on product quality and performance.
A key challenge in protein formulation is the formation of aggregates. Aggregation can occur at multiple stages of the product lifecycle and is frequently initiated by stress factors such as pH variation, ionic strength, or handling processes. Even low levels of aggregation can compromise biological activity, alter pharmacokinetics, and increase the risk of immunogenic responses.
Detecting aggregation early is critical but remains analytically challenging. Many conventional techniques provide averaged measurements that can mask the presence of sub-visible particles and heterogeneous populations. As a result, early-stage instability can go undetected until it manifests in later development phases.
With NanoSight you can:
✔ Early detection of protein aggregation at the nanoscale
✔ Particle-level insight into formulation stability and behaviour
✔ Reproducible, quantitative data to support confident decision-making
Protein stability is rarely lost in obvious ways. It is usually a gradual, invisible process that begins at the nanoscale long before it impacts performance. The challenge for development teams is not just measuring stability but understanding it early enough to act.
This is where NanoSight Pro becomes valuable, giving you a clearer view of what is really happening inside your formulation so you can move forward with confidence.

Protein instability often develops silently, with sub-visible changes accumulating long before they are detectable using conventional methods. These hidden risks can compromise product quality, delay development timelines, and increase the likelihood of costly late-stage failure.
These risks are difficult to identify because they originate at the nanoscale, where early aggregation events begin. Traditional analytical techniques often lack the resolution or sensitivity to detect low-abundance particle populations, particularly in heterogeneous samples. As a result, critical early warning signs are frequently missed.
Protein therapeutics can appear stable during early development, only to exhibit instability during scale-up, long-term storage, or real-world handling conditions. Small changes at the nanoscale can evolve into significant issues, including visible aggregation, reduced efficacy, and compromised safety profiles.
These late-stage failures are often the result of undetected particle formation and growth. Without detailed insight into particle populations and behaviour, it becomes difficult to predict how formulations will respond under stress or over time.
NanoSight Pro addresses this challenge using nanoparticle tracking analysis, enabling direct visualisation and measurement of individual particles in solution. This approach provides early detection of aggregation and a deeper understanding of formulation behaviour, supporting more informed decision-making throughout development.
Protein aggregation begins at the nanoscale, often long before it becomes visible or impacts bulk measurements. Detecting these early-stage events is essential to maintaining stability and preventing downstream issues.
NanoSight Pro enables direct observation and quantification of individual particles, providing a level of sensitivity that goes beyond traditional ensemble techniques. This allows researchers to identify low levels of aggregation and monitor how particle populations evolve under different conditions.
With NanoSight Pro, you can:
✔ Detect low-abundance aggregates before they impact product quality
✔ Quantify particle concentration across defined size ranges
✔ Monitor aggregation behaviour under stress conditions
Early aggregation is one of the clearest indicators that a formulation may not hold up under real-world conditions. The sooner you can detect it, the more control you have over the outcome. NanoSight Pro gives you that early visibility, helping you identify instability before it becomes a problem and giving your team the confidence to refine formulations proactively.
Formulation variables such as pH, ionic strength, and excipient composition play a critical role in protein stability. Small adjustments can have significant effects on aggregation behaviour, making optimisation both essential and complex.
By providing detailed insight into particle size distributions and concentrations, NanoSight Pro enables more precise evaluation of formulation changes. Researchers can assess how different conditions influence stability and identify optimal formulations more efficiently.
With NanoSight Pro, you can:
✔ Compare formulation conditions with greater accuracy
✔ Identify stability-enhancing parameters early in development
✔ Support robust stability profiling and shelf-life prediction
Formulation development is often a balance of small adjustments that can have large effects. Without clear data, optimisation becomes slow and uncertain. NanoSight Pro provides the level of detail needed to compare conditions accurately, so you can make smarter formulation decisions faster and reduce the number of iterations required to reach stability targets.
Protein formulations are rarely uniform. Heterogeneous particle populations can exist within the same sample, influencing stability, efficacy, and safety. Understanding this complexity is key to effective characterisation and control.
NanoSight Pro tracks individual particles in real time, allowing researchers to distinguish between different populations and observe their behaviour dynamically. This provides a clearer understanding of how proteins interact, aggregate, and respond to environmental changes.
With NanoSight Pro, you can:
✔ Resolve multiple particle populations within complex samples
✔ Track particle behaviour under changing conditions
✔ Gain deeper insight into protein interactions and stability mechanisms
Not all particles behave the same, and in protein formulations, that variability matters. Understanding how different populations form and evolve can be the key to unlocking better stability and performance. NanoSight Pro gives you the ability to see and measure that complexity directly, helping you build a more complete and more reliable picture of your product.
Ensuring protein stability requires more than bulk measurements. It demands precise, particle-level insight into aggregation, heterogeneity, and formulation behaviour. NanoSight Pro delivers this capability, enabling researchers to detect instability earlier and respond with confidence.
