In order for proteins to manifest their proper biological and therapeutic effect, their conformational and structural integrity must be maintained at all stages of the development and commercialization process. Thus, for the development of Biotherapeutics it is essential to find optimal (solution) conditions to stabilize the Drug Product such that we can ensure its safety, biological function, structural integrity, and storage for long term under unfavourable and favourable conditions.
To meet the requirements of current clinical indications with respect to drug delivery, highly concentrated therapeutic protein drugs up to 100-200 mg/ml are necessary. In order to achieve such concentrations, a number of protein properties like solubility, self-association, solution viscosity, and protein aggregation have to be controlled. The large dynamic range of the Prometheus NT.48 allows for analyzing thermal unfolding and re-folding in solutions containing protein concentrations between 250 mg/ml down to few µg/ml. Moreover, measurements with rather viscous sample solutions as sometimes observed by highly concentrated formulations can be performed. Thus, it can be utilized for both, stability screening during early phases of drug discovery where only small amounts of protein are available, as well as for formulation screening campaigns of highly concentrated samples. The capabilities of the Prometheus NT.48 itself and in combination with other complementary biophysical tools enables for a better understanding of conformational and colloidal properties of the protein candidate and their impact on macroscopic solution properties. However, in some cases, the Prometheus NT.48 allowed us to perform thermal stability screening with otherwise structurally very complex proteins which were virtually not amenable to any orthogonal biophysical technique.
Moreover, the Prometheus instrument allows for label-free analysis of 48 samples simultaneously independent of their protein concentrations (high dynamic range) and selected solution conditions and/or –compositions. Unlike other techniques the Prometheus NT.48 measurements remained unaffected by any excipient, sugar, detergent or additive. Altogether, the Prometheus instrument enables for very flexible experimental design and provides maintenance-free instrumentation. In addition, our obtained data demonstrate very high reproducibility, consistency, the robustness and precision of this particular technology. The outstanding construction design allows for on-the-fly detection of fluorescence intensity resulting in impressive data point density that there is virtually no need for data fitting.
I personally also highly appreciate the very intuitive software allowing for rapidly setting up the experiment and evaluation of obtained data. The software being developed allows for rapid/easy data analysis, data interpretation and exportation to other data processing software.

DuPont Industrial Biosciences recently acquired its first Prometheus NT.48 nanoDSF instrument. We went through an extensive head to head comparison among other similar technologies and the nanoDSF stood out like a champion. We quickly fell in love and made it the new workhorse in our lab. The instrument provides great data quality of denaturation events with impressive signal to noise ratio, high density of data points, and extraordinary reproducibility making day to day analysis consistent and trustworthy. In addition, the instrument is straight forward to use and data very simple to analyze. We literally, got it, plugged it and started playing in no time.
We started employing the Prometheus to characterize protein samples in early stages of development as well as evaluating formulation stability of super concentrated protein solutions. The instrument is very versatile since measurements require very small sample volume, minimal effort in sample preparation and can handle relevant industrial protein concentrations of up to ~200 mg/mL. In this context, we appreciate the easy sample handling since samples are loaded directly from stock solutions into self-filling capillaries avoiding time consuming and complicated sample preparation steps, even for ultra-concentrated samples. Denaturation events missed by other DSF-type measurements, especially with super concentrated protein sample solutions, are clearly revealed through the high density of data points, yielding same data quality as the gold standard DSC.
Overall, we are very pleased and impressed with the many great qualities of the Prometheus. It will certainly allow us to bridge the gap between molecule screening, selection and product development. We are grateful to NanoTemper for creating this unique biophysical tool as well as for their outstanding and one of a kind customer service.
