SV-AUC is an important part of a complete biosimilarity study. The regulatory bodies like FDA and EMA a more and more insistent on  seeing SV-AUC data for the submission. ZentriForce Pharma is your partner for the development of a robust and specific SV-AUC method. Please follow the link for more information.

SV-AUC is a high-resolution method for the determination of soluble aggregates. It can be seen as the gold standard and can be a helpful tool, especially in cases of troubleshooting. Additionally. it is widely used for the verification of size exclusion chromatography methods.  For more information about the use of SV-AUC in biopharmaceutical development please follow the link.

Gene therapy is a comparably new trend in biopharmacuetical development. Therefore, there is not yet a fixed portfolio of standard analytical approaches. However, it is clear that SV-AUC is one of these techniques.  It is the only technique to separate species due to their size and density at the same time. Therefore, SV-AUC can be used to measure on of the most crucial quality attributes (the ratio of particles without genetic information) of your gene therapy products. Our scientists have already worked with a wide range of gene therapy products (ranging from small DNA/RNA complexes over adeno-associated viruses and lysosomal formulations up to complete viruses) and are keen to assist you with your very molecule. If you need more information please follow one of the following links.

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. Please follow the link for more information.

Sedimentation Velocity Analytical Ultracentrifugation (SV-AUC)

Sedimentation velocity analytical ultracentrifugation (SV-AUC) is the established gold standard in aggregation analytics. SV-AUC is a first principle method. Measurements can deliver 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 results that are influenced by interactions between sample and column material, SV-AUC does not rely on a stationary phase and is thus not prone to change the sample composition. 

Additionally, sedimentation velocity analytical ultracentrifugation sample is not diluted with mobile phase during measurements.  The technique’s advantageous properties are the reason for which regulatory bodies like FDA and EMA show steadily increasing interest in SV-AUC results. It is advisable to verify SEC results by sedimentation velocity analytical ultracentrifugation.

SV-AUC measurements provide information on sample composition as well as on the nature of the observed species (molecular weight, sedimentation coefficient and shape information). This data not only helps to quantify impurites it also helps to identify the detected impurities.

Sedimentation Velocity Analytical Ultracentrifugation (SV-AUC) Service

Zentriforce Pharma is a contract research organization that specializes in analytical services with a focus on hydrodynamic methods. Although we routinely conduct biosimilarity and gene therapy studies, we are experienced in the development of sedimentation velocity analytical ultracentrifugation (SV-AUC) methods for a large variety of samples. ZentriForce Pharma offers SV-AUC services under BSL 1 and 2.

Our scientists have worked with a wide range of biopharmaceutical products. The experience we gained in AUC method development enables us to provide methods featuring both, highest quality results and maximum throughput (up to 16 samples per run).  Consequently, we can guarantee to keep the cost per sample as low as possible. As we perform all measurements on the new Optima Analytical Ultracentrifuge, we are able to perform high resolution data and high throughput services.

Additionally, we are able to provide advanced quality data evaluation approaches, such as Ultrascan. Our computer cluster allows us to carry out all data evaluation at our own facility.
