Drug Delivery

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.

Viscosizer TD provides automated relative viscosity measurements with high reproducibility at low viscosity, to help identify molecules with abnormally high viscosity-concentration profiles at low sample concentrations as early as possible in the development pipeline

The term ‘packaging’ may not immediately evoke excitement – but without innovation in the field, some therapies wouldn’t even reach market. In other words, don’t judge a box by its cover because there’s more to packaging than meets the eye… and even more lies on the horizon.

Scientists use hydrophobic plasma and AC/DC’s ‘Thunderstruck’ to coat porous silicon microparticles for drug delivery

Drug discovery doesn’t always begin in the lab…

AAV vectors are a promising tool for gene therapy and regenerative medicine, but only if they can be manufactured efficiently

A “smart” synthetic patch uses live pancreatic cells to painlessly deliver insulin through microneedles – on demand

This application note explores the use of the Morphologi G3-ID for Morphologically-Directed Raman spectroscopy (MDRS) to identify and analyze contaminants including protein aggregates present in a stressed sample of lysozyme, and to compare particles held in suspension within a thin path wet cell with those collected on a filter membrane.

Work performed in conjunction with Spiber Technologies, Uppsala, Sweden. Use of dynamic and electrophoretic light scattering to assess the effects of protein formulation composition
