When an industry grows rapidly, innovative approaches are required to ensure sustainable growth. Here, we speak to leaders at Ireland’s National Institute for Bioprocess Research and Training – NIBRT – to find out how a focus on talent, training and technology is changing the face of the field.

After finally breaking into the US market, biosimilars have created a real buzz in the industry, but the best practice for demonstrating similarity can be daunting to say the least.

Automated image analysis has been combined with Raman spectroscopy to achieve component-specific size and shape analysis of active ingredients, supporting and accelerating the commercialization of both innovator and generic pharmaceutical products.

Which equipment can measure how the particle size delivered by a dry powder inhaler (DPI) changes as a function of applied air flow rate, providing a deagglomeration profile which can be used to compare the performance of different formulations in a device and improve drug delivery.

Particle agglomeration can compromise the clinical efficacy of pharmaceutical products and must therefore be closely controlled. This article provides practical guidance on using automated imaging for efficient agglomerate detection.

High concentration, low-viscosity, stable therapeutic protein formulations are needed to enable low-volume parental administration. This article explores how a fully automated light scattering system supports the rapid screening of small volume samples in well plates for the rapid identification of suitable biologics during early phase development.

Measurement and characterization of binding interactions between proteins and low-molecular weight (LMW) ligands are a focus of academic research and drug discovery. Isothermal titration calorimetry directly measures heat released or absorbed in a binding event, providing means for studying protein-small molecule interactions in solution without the need for labeling or immobilization. Importantly, ITC is often utilized to characterize differences in entropic and enthalpic contributions to binding of novel ligands.

In this application note we describe the use of Nanoparticle Tracking Analysis (NTA) for size and concentration measurements of drug delivery nanoparticles. In addition, by using a fluorescently tagged drug molecule, it was possible to determine how many drug delivery nanoparticles had successfully been loaded with drug molecules.

The ability to compare concentration data across users, instruments and sites is a key requirement for many applications. Concentration repeatability and reproducibility are greatly improved with the application of the NTA concentration measurement upgrade, which has also been shown to reduce the influence of user selected capture and analysis settings on measurements. This application note describes the improvement in accuracy and precision of concentration measurements over a wide range of sample sizes, concentrations and materials.
