Dynamic light scattering is known as a fast and efficient screening method for aggregate / particle detection. Therefore, it is widely used within biopharmaceutical development. It is used to close the gap between results gained in the range of small soluble aggregates via size exclusion chromatography (SEC) and particle methods such as light obscuration (LO) or micro flow imaging (MFI). Due to the high sensitivity toward large species, even small impurities can be detected within the measurement range (0.5 nm – 1 µm). For more information please follow the link.

µ-DSC is a well-stablished method for thermodynamic analysis of biomolecules, due to combined high data reproducibility and method sensitivity, and the “structural fingerprint” character of thermograms that is unique for each biomolecule. In addition, µ-DSC provides a direct and label-free measurement of thermal stability without the same solvents restrictions that apply to spectroscopic methods.

Temperature Stability Testing 

Temperature stability is a critical parameter in drug product development, especially during formulation development or within biosimilarity studies. The aggregation temperature (Tagg) and melting temperature (Tm) may be determined by application of a heat ramp. Stress studies at isothermal temperatures are applied to monitor time-dependent structural changes.

ZentriForce Pharma Instrumentation 

Zentriforce Pharma uses the DynaPro®Plate Reader III for temperature stability testing. We offer highest quality dynamic light scattering (DLS), as well as static light scattering (SLS) measurements. The combination of both allows us to simultaneously monitor, the formation of large particles as well as changes in the active pharmaceutical ingredient (API), such as dimer formation, and its soluble aggregates.

The DynaPro®Plate Reader III  can perform measurements at small sample volumes (down to 4 µl).  At the same time, the instrument offers highest available sensitivity and allows us to measure at low concentrations.

The use of a well-plate-based approach provides the opportunity to screen a large number of samples in parallel. This reduces the cost per measured sample. Another benefit that comes with this setup is the elimination of contamination risk of the instrument by previously measured samples. Furthermore, comparability of results increases by simultaneous measurement of multiple samples.  We also offer to implement a system suitability check and/or a reference standard into your sample set.

For a more detailed description of dynamic and static light scattering theory please follow the link.

Accessible Parameters

The simultaneous detection of both, SLS and DLS signals, allows us to screen the melting (Tm), aggregation (Tagg) and onset temperatures (Tonset) at the same time. This information can help to understand both the temperature dependence of the colloidal and conformational stability at the same time. 

Additionally, we offer to set up isothermal stress studies with a high number of samples simultaneously. We are thus able to assess the temperature stability of different samples, e.g. within a formulation development.

Gene Therapy
For gene therapy product development, traditional quality attributes (e.g. purity) as well as new quality attributes (e.g. the ratio of particles that carry nucleic acids to empty particles) must be addressed. The diversity of approaches for gene therapy API analysis adds a further challenge to product characterization. Our scientists have worked with a wide range of different gene therapy products, ranging from small DNA / RNA complexes over lyposome-based carrier systems and adeno-associated viruses (AAV) to viruses that are several hundred nanometers in size.

Biosimilarity
Within biosimilarity studies attention is on the collection of evidence that proves that no differences (larger than method variability) in structure and purity exist between a proposed biosimilar and the reference product. Evidence is collected through extensive analytical testing. The different focus between development and biosimilarity testing require an adjusted mindset and a customized study design for the respective task. ZentriForce Pharma can be a valuable partner on your way to release a biosimilar

Peptides
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.
