The Biospecimen Pre-analytical Variables (BPV) Program is a National Cancer Institute-sponsored study to systematically assess the effects of pre-analytical factors on the molecular profile of biospecimens. A robust biospecimen collection infrastructure was established to prospectively collect bi...

This dataset contains mass spectrometry-based proteomic analyses of human plasma samples processed through five distinct proteomics workflows: neat plasma, perchloric acid precipitation with neutralization (PCA-N), and three bead-based enrichment methods (SAX magnetic beads, Sera Sil 700 magnetic be...

This dataset contains SOMAscan proteomic data obtained from human cerebrospinal fluid (CSF) and plasma samples to evaluate the impact of pre-analytical variables (PAVs) on proteomic stability. The study systematically assessed common processing factors such as storage temperature, time-to-processing...
