Fup UC Level-0 Example Data set

Description

Mass Spectrometry measurements of plasma protein binding (PPB) via ultracentrifugation (UC) for per- and poly-fluorinated alkyl substance (PFAS) samples. Experiments were led by Dr.s Marci Smeltz and Barbara Wetmore \insertCitesmeltz2023plasmainvitroTKstats. This data set is a subset of experimental data containing samples for 3 test analytes/compounds.
