Peptide-level Expression Data (e_data) with technical replicates

Description

A dataset containing the quantified mass spectra for 21,802 unique peptides collected on a Thermo LTQ-Orbitrap Velos Mass Spectrometer (Thermo Fisher Corporation, San Jose, CA, USA). Columns represent technical replicates within each of 32 biological samples (2 technical replicates per sample).

Format

A data.frame with 21,802 rows (peptides) and 65 columns (peptide identifier and LC-MS runs). Column names have the following tags:

Mass_Tag_ID

Peptide mass tag identifier

1:0, 1:7

Indicators representing dilutions of mouse plasma to Shewanella oneidensis MR-1

Rep1, Rep2

Indicators of technical replicates within a biological sample
