The goal of the UNC CFAR Clinical Pharmacology and Analytical Chemistry (CPAC) Core is to Provide Comprehensive Study Design, Bioanalytical, and Data Analyses Support to Animal and Human Clinical Pharmacology Investigations in the HIV/AIDS arena.

CPAC Receives Grant for New Mass Spectrometry Imaging Instrument

The Clinical Pharmacology Core has recently installed a novel analytical instrument for mass spectrometry imaging (MSI) of biological matrices based on infrared matrix-assisted laser desorption electrospray ionization (IR-MALDESI). Using this approach, the biodistribution of antiretroviral drugs and other novel therapies can be quantified simultaneously within tissue. By combining the resulting maps of analyte distribution with serial images of tissue morphology and immunohistochemistry, drug penetration to sites of action and therapeutic efficacy can be evaluated.
