Technetium-99m (99mTc) is a synthetic radioisotope that is used worldwide to produce radiopharmaceuticals that are mainly used for diagnostic purposes in nuclear medicines. The purity of the final radiopharmaceutical (99mTc-R) can be confirmed by applying chromatographic methods. This method is based on different rates of movement of substances in a…

In this in-depth focus are articles on consistent analytical techniques when changing laboratories and using chromatographic techniques to identify impurities in radiopharmaceuticals.
What’s the difference between High Performance Liquid Chromatography (HPLC) and Ion Chromatography (IC)? What are the capabilities and limitations of each technique? Knowing these differences can actually make a huge difference.
This free poster compiles all basic chromatography principles needed to develop and run flash and prep HPLC methods.
The efficacy, safety and pharmacokinetic properties of a protein therapeutic substantially depend on the molecule having the right structure. This article reviews current methods used for obtaining higher order structure information of biotherapeutics.
Expert View: Eshmuno® CP-FT resin – developed for the flow-through removal of aggregates using frontal chromatography
Eshmuno® CP-FT cation exchange resin is specifically designed to provide efficient removal of monoclonal antibody (mAb) aggregates in the flow-through frontal chromatography mode of operation enabling loading capacities 10-times higher than traditional bind/elute CEX chromatography. It facilitates greater manufacturing flexibility and process intensification while reducing the overall cost for the…
The practice of bottom-up proteomics relies to a large extent on the separation performance that can be achieved with state-of-the art nano LC-MS/MS equipment.
Scientific poster: Nuvia aPrime 4A: a hydrophobic anion exchange resin for refined selectivity and recovery
The elimination of product and process related impurities is essential to the safety and efficacy of biopharmaceuticals.
This whitepaper demonstrates the High Performance Liquid Chromatography (HPLC) separation and analysis technique and highlights the importance of using water of sufficient purity as an eluent and how the arium® pro VF system can facilitate this.
As maintaining the health of the chemist is of top priority, one should recognise potential dangers that can jeopardise the safety of laboratory staff and install measures to sufficiently protect the scientists.
A project backed by major pharma will advance the Lab of the Future with proof of concept software to digitise experiment methods…
PharmaFluidics’ new product launch steers ‘on-a-chip’ separations of complex biological samples to new heights
PharmaFluidics NV is a game-changing innovator in the field of analytical chromatography. The company has devised a fundamentally new way of performing separations by creating nano-LC columns on a silicon chip...
For several decades mass spectrometry (MS) has been used in the characterisation of protein pharmaceuticals.1-3 However, its use in the laboratory for quality control (QC) product release testing has been quite limited for a number of reasons, for example: instrument complexity and software are not readily amenable to validation, extensive…
Scientific Poster: Quantitation of monoclonal antibody infliximab in human plasma by LC-MS/MS using Fab-selective limited proteolysis nSMOL technology
Infliximab, commercially known as Remicade, is a chimeric IgG1 kappa monoclonal antibody (mAb), that targets tumor necrosis factor-alpha (TNF)....
