The secrets of protein secretion: what are the key features of comparative secretomics?

Pages 785-787 | Received 01 Dec 2020, Accepted 22 Jan 2021, Published online: 07 Feb 2021

Figures & data

Figure 1. Overview of the comparative secretomics workflow. Any kind of cell culture model can be analyzed. Therefore, the supernatant (secretome) and cells (intracellular proteome) are collected and prepared according to the media conditions. After proteolytic digestion, the peptides are analyzed by LC-MS/MS. The quantitative analysis will give access to bona fide secreted proteins and the qualitative peptide matching allows to draw conclusion about ectodomain shedding
