Label-Free Proteome Profiling

Dear Colleagues,

The accurate determination of quantitative changes, describing the biological systems, has attracted a considerable amount of interest in the scientific community. Biological processes are regulated through the abundance of proteins. In addition, the relative abundance of each protein in a complex system may influence the modulation of its activity and its function. Over the past decade, mass spectrometry-based proteomics has become an indispensable tool in deciphering the exact abundance of each protein in composite mixtures. Indeed, the fast development of mass spectrometry-based proteomic technologies and the accessibility of powerful data analysis tools have increasingly boosted the transition of proteomic analysis from qualitative to quantitative, with a strong impact on the biological interpretation of protein functions. The described technological improvement, such as the advent of new high-resolution instruments, has allowed us to overcome classical, label-based quantitative approaches and use proteomics to move toward label-free techniques.

This Special Issue invites original and interesting contributions on quantitative proteomic studies and aims to describe the translational applicability of label-free proteomic profiling in a wide range of scientific fields. However, the Special Issue is also open to discussions about the methodological progress linked to quantitative proteomics in order to facilitate the sharing of experimental and technical details in terms of methodological conditions and bioinformatic analysis.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Molecules is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
