Monitoring protein aggregation in injectable vaccines syringes: a new direct & contact-less technique
David Jacob CTO
Keywords: vaccines, protein, in situ measurement, aggregation
Aggregation of proteins and active principle ingredients (API) in injectable biopharmaceutical products remains a major concern impacting the stability and usability of a product. Indeed, Protein aggregation can occur during all stages of the lifetime of a protein therapeutic, including expression, refolding, purification,
sterilization, shipping, storage, and delivery processes [1, 2]. The mechanism of protein
aggregation is still not well understood; but it is known that certain manufacturing stages
like formulation composition, presence of microbial or vial contaminants during cell
culture, and storage influence the risk of chemical degradation, which increases the risk
of physical degradation and the formation of aggregates. In particular, it has been shown
that the storage container environment plays a role like in prefilled syringes for example
where leaking silicone oil from the rubber stopper, and glass delamination can induce
aggregates. In a context of more and more stringent international health regulations
about the control of biopharmaceutical products, the in-situ monitoring of the denaturation and degradation process of therapeutic proteins during production and storage can be a key competitive advantage for manufacturers and researchers
Cordouan will be attending Nanosafe 18 in Grenoble. We will be presenting De Long Microscope and our latest DLS syustem Vasco Kin.
Please join us from the 5th to the 9th of November 2018
CORDOUAN TECHNOLOGIES ANNOUNCES THE RELEASE OF VASCO KIN™ ITS BRAND NEW PARTICLE SIZE ANALYZER.
Keywords: nanoparticle, particle size analyzer, in situ measurement, kinetic study
The VASCO KIN™ is a new generation of nanoparticle size analyzer combining a unique time-resolved kinetic analysis capability with an optical fiber remote probe for in situ measurement. Based on an innovative proprietary Software Time-Resolved Correlation (STRC) technology, VASCO KIN™ is by far the most accurate and versatile particle size analyzer on the market today, opening the field for new and advanced applications in colloids sciences.
Thanks to its 10 years of experience and expertise in NPs characterization, Cordouan Technologies has chosen the best components & cutting-edge technologies for its VASCO KIN™ (Laser, APD, etc.) allowing the best analysis ever done on NPs size distribution in colloids in a minimum time (few seconds needed for great results).
Data post-processing: At the end of an experiment, all data are recorded and stored into a timetable. Users can then post-process the data by selecting the appropriate time slots for correlation processing and size analysis, enabling to select the most relevant data (big particles scattering events suppression, no artificial/external influence during the experiment, etc.).
A unique “Time slicing” function allows to create discrete time window analysis with adjustable duration and delay. Building up, in a very accurate way, the Kinetics of an experiment can be done automatically by the NANO KIN® software in just a few clicks and a 2D colormap representation displays size distributions over time (see Figure 1).
Thanks to this technique, analysis of turbid samples, kinetics of fast chemical reaction, study of very small NPs in high dilution, dark and concentrated samples are getting very easy!
Major innovations & features
- In situ & contactless optical fiber remote probe: small footprint, non-invasive
- Proprietary Time-Resolved correlation for real time Kinetics
- Frequency stabilized laser & artefact-free APD detector for ultra-fast measurement

- Measurement of diluted and/or subnanometer samples.
- High resolution kinetic monitoring (time resolution: down to 200 ms)
- No moving parts – easy maintenance, reliable
- High throughput measurements
THANKS TO ITS DIRECT EXPOSITION TO THE NORTH-ATLANTIC GYRE, GUADELOUPE (FRENCH WEST INDIES) IS A FAVOURABLE LOCATION TO STUDY MARINE MICROPLASTIC WEATHERING AND ITS NANOSCALE DEGRADATION. #7ECONTINENT
Further analysis on a huge quantity of collected samples will be conducted by several French teams. The results of this campaign should be published very soon. Stay tuned !
