Are you tasked with the bioanalysis of antibody drug conjugates (ADCs)? If so, you know they represent a rapidly growing class of biotherapeutics, but their unique chemical structure makes quantitative analysis particularly challenging.
So, what is the best technique to create a novel quantitative analysis solution that accelerates method development and improves the performance of ADC pharmacokinetic assays?
Typically used Ligand binding assays (LBA) such as Enzyme-Linked Immunosorbent Assays (ELISA) have many advantages. However, LBAs can suffer from high variability, limited dynamic range, and problems with selectivity. An alternative comes with liquid chromatography-tandem mass spectrometry (LC-MS/MS), which has found widespread use in the quantitative analysis of small molecule drugs. While LC-MS/MS assays are exceedingly selective, with excellent dynamic range and reproducibility, they can lack sensitivity when applied to protein therapeutics.
In search of a solution, our experts developed a unique workflow with outstanding results. We combined a universal immunocapture enrichment strategy with sample preparation and a hybrid LBA microflow LC-MS/MS technique and applied it to the total antibody analysis of the ADC of Ado-trastuzumab emtansine in plasma.Read the full report in Chromatography Today >

This hybrid LBA microflow LC-MS/MS workflow using high capacity streptavidin coated magnetic beads provides a customizable immunocapture strategy that enables the rapid development of high sensitivity pharmacokinetic assays of biotherapeutics during pre-clinical or phase HC studies.
The workflow applies to mAB based therapeutics and results in faster assay development with wide dynamic range, high selectivity, and high sensitivity, with a lower LLOQs than typically achieved by LC-MS/MS using a direct plasma or pellet digest.

In your lab, time is not just a resource. It’s a necessity and every moment counts. Yet, unplanned downtime can disrupt this delicate balance. Even a brief interruption can set your team back in multiple ways.
In a recent webinar, which is now available on-demand, Holly Lee powerful strategies to tackle complex residue testing. From boosting throughput to fine-tuning method sensitivity, Holly shared key ways to maximize performance across large pesticide panels.
Whether we are raising glasses of rosé in a vineyard in France or enjoying a lager in a casual street restaurant in China, it is likely that the last thing on many people’s minds is the chemical risks from their beverage. Unless you work in food science, then it might actually be the first thing.
