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 for more information.
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. For more 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.
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.
μ-DSC is highly effective to demonstrate biosimilarity, which is done by the direct comparison between the thermogram (a structural “fingerprint”) of the reference product and a biosimilar candidate. In addition, it provides high data reproducibility and sensitivity to factors influencing thermal stability and conformational changes.

Within this section we focus on protein / peptide-based products. Protein (especially antibody) based products are the largest group of biopharmaceutical products. Despite increased interest in gene therapy products, antibody-based products will dominate the pharmaceutical industry for a long time. For detailed information please follow the link.
For biopharmaceutical development we focus on support of production optimization, the development of analytical methods, or assistance in formulation development. For further information please proceed to our biopharmaceutical development page.
Despite being far less complex than full proteins, analytical handling of peptides is challenging. Species as small as peptide-based APIs require analytical instrumentation to be run at its physical limits. Expertise and extensive experience in working with such materials is imperative for successful method development. Our scientists have worked with a large number of peptide-based APIs, with sizes down to 1 kDa. They will be valuable assets where expertise and consultation in analytical method development are concerned. For further information please proceed to our peptide page.

The aim of biosimilarity studies is to provide evidence that no differences larger than method variability exist in the structure and purity of a proposed biosimilar and the reference product. Supporting data is collected through extensive analytical testing that may be performed in R&D laboratories. However, as all results are already relevant for data submission to the authorities, the results must be indubitable and trustworthy. Therefore, it is critical for successful admission of your biosimilar to work with a reliable partner that you (and the FDA and EMA) can trust to deliver high quality services. ZentriForce Pharma has established a laboratory quality system that closely follows extensive and detailed guidelines provided by the WHO and the principle of “writing what you do and doing what you write”. For further information, please follow the link to a description of our ZentriForce quality system.
Our scientists have supported numerous biosimilarity studies and can be valuable assets where expertise and consultation are concerned. We offer a wide range of analytical services that provide valuable data for your studies.
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.

We recommend to couple a HPLC instrument with a multi-angle laser light scattering detector (MALLS) to collect information on each eluted species individually and strengthen your claim of biosimilarity.

Authorities show increased interest in orthogonal methods to verify SEC results. Among these, AF4 and AUC are the most prominent. Both are first-principle methods. AF4, however, is a comparably complex technique that requires an experienced scientist for the development of robust and specific AF4 methods. ZentriForce Pharma is a valuable partner for AF4 biosimilarity studies.

Approval of biosimilars depends on the ability to demonstrate similarity with the innovator. In addition to the above listed analytical portfolio supporting biosimilar development, ZentriForce Pharma offers analysis via DSC, a gold standard method for thermal stability characterization of biomolecules. The DSC thermogram profile has the uniqueness of a “structural fingerprint” and is therefore very useful in identifying a molecule or comparing it to another. In addition, DSC serves as an excellent screening tool during formulation development to test for the most temperature-stable products.
