Abstract
In order to validate the changes in protein expression, measured via a newly developed semi-automated workflow for quantitative analysis of the newly synthesized proteome (https://www.biorxiv.org/content/10.1101/2023.03.03.530942v1.full), targeted proteomic analysis was carried out.
Experiment Description
Hela cells were treated with either 0.5% (w/v) BSA or 10 ng/mL recombinant IFNg for either 4h or 24h. Samples for PRM analysis were prepared using SP3 (https://www.embopress.org/doi/full/10.15252/msb.20145625). Quantitative measurements of tryptic peptides, was carried out using an EASY-nLC 1200 system coupled to a Q Exactive HF mass spectrometer.

Overview of the TIC normalized peak areas of the targeted peptides, analysed in Hela cells treated with 10 ng/mL IFNg or 0.5% BSA for 4 h and 24 h, using PRM measurements. Data are based on 3 experimental replicates.

The spectral library, which was used in the analysis, was generated using Prosit (https://www.nature.com/articles/s41592-019-0426-7). More specifically the Prosit_intensity_hcd_2020 and Prosit_2019_irt intensity and retention time prediction models were used.

A list of peptide targets, with defined charge states and normalized collision energies was used as input for the prediction.
