Sedimentation velocity analytical ultracentrifugation (SV-AUC) is the gold standard in aggregation analytics. The importance of SV-AUC results is growing, especially in biosimilarity studies, and also within the development of gene therapy products. ZentriForce Pharma offers SV-AUC services for a wide sample spectrum. For more information please follow the link.
Asymmetrical flow field-flow fractionation is an orthogonal method to size exclusion chromatography (SEC) and sedimentation velocity analytical ultracentrifugation (SV-AUC). While the other two techniques are limited to comparably small size ranges, AF4 methods can cover a measurement range from 1 nm up to 1 μm. AF4 can be used with the same mobile phase as SEC but does not depend on a stationary phase. Therefore, it is suitable to back up SEC methods. If you need further information please follow the link.
Dynamic light scattering is a crucial part of every biosimilarity study. It is a fast and efficient screening method for aggregate and particle detection. DLS closes the gap between the range of small soluble aggregates that are detected via size exclusion chromatography (SEC), and particles analyzed by methods such as light obscuration (LO) or micro flow imaging (MFI). Owing to the technique’s high sensitivity towards large species, even small impurities can be detected within the measurement range (0.5 nm – 1 µm). If you need further information please follow the link.
Size exclusion chromatography (SEC) is the most widely used technique for aggregate determination in biopharmaceutical development. Obvious advantages are the easy handling and the good reproducibility that this method provides. To avoid misleading results, it is essential to develop a method that is not solely based on the observed elution pattern of the sample, but that also characterizes each observed eluted species individually. This is possible by coupling a multiangle laser light scattering detector (MALLS) with the HPLC instrument. With this information we are able to strengthen your claim of biosimiliarity.

AUC is a first principle method. Therefore, the separation mechanism is well understood and extensively described. Please follow the link to a detailed description of AUC theory.
Even though SV-AUC is with its more than 100 years of history a by far older technique than most others currently used within biopharmaceutical development. It is one of the most complex in regards of data evaluation. We have setup our own supercomputer cluster to be able to offer you several different data evaluation approaches, without the need of your data leaving our premises. We currently offer Sedfit and Ultrascan data evaluations. However, if we see the need to use a different software for your very molecule we have the knowledge base to do so.

Looking back at a history of nearly 100 years in scientific research and development, SV-AUC remains highly relevant as an analytical technique. Within biosimiliarity studies, SV-AUC is commonly applied to characterize the API and quantify aggregates and fragments. SV-AUC is a first principle method and delivers information such as relative concentrations, sedimentation coefficients, molecular weights and shape information (frictional ratio) within a single measurement. While its orthogonal technique SEC might show unexpected (and falsely interpreted) results due to interactions of sample and column material, SV-AUC is not prone to change the sample composition. For this reason, regulatory bodies like FDA and EMA show steadily increasing interest in SV-AUC results.
Please follow the link to our SV-AUC theory page to learn more about sedimentation velocity analytical ultracentrifugation.
Sedimentation velocity analytical ultracentrifugation (SV-AUC) is regarded as the gold standard for aggregation analytics.
SV-AUC is a first principle method, and in contrast to size exclusion chromatography (SEC), SV-AUC does not rely on a stationary phase. Interactions between sample and stationary phase might have an influence on the measured sample composition. Sample may, for example, specifically absorb species, split oligomers, or form such. Furthermore, SV-AUC samples are not diluted by a mobile phase. For these reasons, regulatory bodies like FDA and EMA show steadily increasing interest in SV-AUC results. We therefore advise to always verify SEC results by a first principle method like SV-AUC.
SV-AUC measurements provide information on sample composition and on various crucial parameters of the observed species, such as molecular weight, sedimentation coefficient and shape. This potentially helps to identify impurities.
Our scientists have worked with most commercially available biopharmaceutical products. Our experience allows us to keep your expenses on method development low. Additionally, we provide highest quality results while keeping the throughput high (up to 14 samples per run). This reduces the cost of sample analysis.
Our instrumentation is state-of-the-art and allows for high resolution and high throughput measurements at the same time. We carry out all measurements on the new Optima Analytical Ultracentrifuge and additionally offer high quality data evaluation approaches, such as Ultrascan. Our own computer cluster allows us to perform all data evaluation at our own facility. Data security has highest priority.
We know that all SV-AUC measurements are relevant for your regulatory submissions. Zentriforce Pharma has implemented a strict quality system to assure that the quality and traceability of all SV-AUC data is guaranteed. We apply a wide range of quality related standard operation procedures (SOPs).
