PKMS Knowledge Center
Pharmacokinetics and Mass Spectrometry Core Facility (PKMS) is a shared core resource facility in UM, and serves the scientific research community at UM and beyond with state-of-the-art expertise, methodology, and instrumentation. We are pleased to offer a complete PK service to your research projects with different options including collaboration, Fee-for-Service (FFS) and self-service. Please check our complete PK analysis service - from in vitro and in vivo drug discovery to bioanalysis and Mass spectrometry imaging.
Pharmacokinetics (PK) is the study of the time course of drug’s absorption, distribution, metabolism, and excretion (ADME), what the body interact with a drug, related to the movement of drug into, pass, and out of the body. In order for a drug to be effective in the body, enough of the active form must reach the target to elicit the desired effect. The compound with the best activity against the target enzyme or receptor may have very poor ADME characteristics such as metabolic instability or poor intestinal absorption. When choosing a lead candidate from multiple compounds, the activity of the drug in the efficacy screen must be balanced with acceptable ADME and stability characteristics. Pharmacokinetic studies with mass spectrometry bioanalysis can provide the quantitative information about the half-life of the administrated compound from in vitro and in vivo test, and more useful information of how quickly it can be metabolized or excreted by enzymatically or nonenzymatically. To track the drug accumulation and distribution in organism from in vivo PK study, the mass spectrometry imaging and quantification can come up with innovative solutions to quantify dynamic drug exposures in all targeted tissues, or using artificial intelligence modeling to predict the drug exposure in disease or normal organs.

Mass spectrometry imaging (MSI) is an emerging technique that allows molecular visualization of the distribution of drugs, lipids, peptides, proteins and metabolites in a two-dimensional space directly in biological tissues. MSI allows unlabeled drug compounds and drug metabolites to be detected and identified and quantified according to their mass-to-charge ratios (m/z) at high resolution in complex tissue environments. This technique has better specificity and provides the possibility to combine histological data with MS ones and to visualize simultaneously the distribution drugs or biomarkers in relation to tumor heterogeneity, provide new understandings of the dynamic processes impacting drug uptake and metabolism at the local sites targeted by therapy.
We have a state of the art MALDI/DESI SYNAPT G2-Si High Definition Mass Spectrometry (Waters®) in our Pharmacokinetics and Mass Spectrometry Core Facility (PKMS). Using the MALDI and DESI ion source together with T-Wave ion mobility technology, our experienced team of mass spectrometry imagers can provide distribution profiling information for a wide range of sample types, such as tissue specimens, industrial and biological materials, horticultural specimens, and microbiological populations. We offer MSI sample preparation, including cryo-sectioning and microtome techniques, histological staining, and tissue microscopy. We can also combine imaging data with data acquired by different analytical techniques to deliver more comprehensive results. Our team works with you to identify MSI approaches to address your application requirements.
