Current pharmacokinetic (PK) and toxicological studies pose an increasing demand on the volume of blood available from study animals, especially when the study involves small rodents. As a response, microsampling techniques have been introduced into bioanalytical studies.

Dried blood spots (DBS) and capillaries are the two most commonly used microsampling techniques. In this presentation, we present how microsampling can generate high quality bioanalytical data and accurate PK profiling, we also present a unique sample handling method utilizing pre-scored capillaries developed by Frontage (PA, USA), and how this overcomes some of the limitations with the conventional capillary microsampling approach.

Frontage supports early drug discovery with various immunoassays for proteins and therapeutic antibodies to support pharmacokinetics/toxicokinetics (PK/TK), pharmacodynamics (PD), and biomarkers analysis.

Critical reagents – the key components used in LBA – are central to ensuring the consistency and reliability of the assay and can often slow the progress of LBA due to limited availability. In this panel discussion, we examine the current scope of LBAs, the advantages and limitations including matrix interference, as well as the solutions for overcoming these. Additionally, we explore the platforms currently used and the key factors to consider when choosing a platform. Finally, we will highlight key areas for progression.
