Cyclic peptides, known for their stability and high specificity, are promising therapeutic agents in the fight against cancer, infections, and autoimmune diseases. However, developing effective cyclic peptides presents numerous challenges, including poor pharmacokinetics, efficacy, and toxicity. Traditional methods like liquid chromatography tandem-mass spectrometry (LC-MS/MS) often struggle with resolving isomeric linear peptide metabolites, posing significant risks in safety, efficacy, and regulatory approval. In this paper, Komal Kedia, PhD, will share how she leveraged MOBIE’s high-resolution ion mobility-mass spectrometry (IM-MS) system to achieve a 72% reduction in run times, 200% greater resolving power, and enhanced accuracy in identifying “soft spots” prone to enzymatic degradation.
Justin Miller-Schulze and Smith Purdum explain how machine learning and chemometrics can improve fire debris classification in forensic science applications.
This week, the Chromatography Online website observed National Forensic Science Week with expert interviews on how chromatography helps solve cases, plus career stories from women in analytical science and new research on detecting rat poison in cats and tracking mold toxins in gluten-free pasta.
Kinjal Bhatt argues inclusion advocacy shouldn't fall on women alone, while Ina Varfaj credits sharing the load and learning to say no for avoiding burnout.
Steven Ray Wilson defines organ-on-a-chip as organoids on microfluidic devices, tracing their small, complex samples to the case for automated online LC–MS.
