Author Guidelines

Focus and Scope

The Trends in Peptide and Protein Sciences is a peer-reviewed, print-online, scientific journal owned by Protein Technology Research Center, Shahid Beheshti University of Medical Sciences and documents in all important aspects of the research in peptides and proteins focusing on analytics and impurities, bioinformatics, biopharmaceuticals and vaccines, biotechnology, chemical synthesis, conformational analysis, design and development of protein therapeutics, determination of structure, enzymology, folding and sequencing,  formulation and stability, function, genetics, immunology, kinetics, modeling, molecular biology, pharmacokinetics and pharmacodynamics of therapeutic proteins and antibodies, pharmacology, protein engineering and development, protein-protein interaction, proteomics, purification/expression/production, simulation, thermodynamics and hydrodynamics and protein biomarkers. The aim of this journal is to publish high quality original research articles, reviews, short communications and letters and to provide a medium for scientists and researchers to share their findings from the area of peptides and proteins. Trends in Peptide and Protein Sciences publishes four issues a year.


Electronic Submission of Manuscript

Manuscripts must be submitted online by the Corresponding Author to the Trends in Peptide and Protein Sciences at:

First-time users are required to register at before submitting a manuscript.  Straightforward login and registration procedures can be found on the website.

Note: you should mark "Author" as your role on "My Profile".

By submission, the author(s) confirm that the manuscript (or any parts of it) has not been published previously or is not under consideration for publication in another journal. Previous presentation in any congresses should be mentioned as a footnote in Title page and also stated in the Covering Letter. Furthermore, any illustrations, structures or tables that have been published elsewhere must be reported, and copyright permission for reproduction must be obtained.


Categories of Articles

The Trends in Peptide and Protein Sciences publishes the articles in the following categories:

  • Original Research Articles should be divided into the following sequence of sections: Title page, Abstract, Keywords, Introduction, Materials and Methods, Results and Discussion, Conclusion, Acknowledgements, Competing Interests and References.
  • Review Articles inform readers of the state-of-the-art of a particular area, provide a critical view, or a historical perspective. They should be comprehensive, critical, and balanced. These are contributed by scientists who are leading specialists in their field of expertise, normally at the invitation of the Editors. Authors wishing to contribute a review paper are advised first to contact one of the members of Editorial Board.
  • Short Communications are reserved for short reports of highly important and noteworthy findings in protein and peptide sciences, useful computer softwares, along with a description of relevant applications and the announcement of novel protocols. Short Communications should not exceed 2500 words in length, including references, tables and figures. These manuscripts are followed the peer-review process and will be considered for fast publication, if accepted.
  • Letter to the Editors are intended to stimulate discussion in areas of general concern and controversy in protein and peptide sciences. They should be written in a continuous style and should normally not exceed 1500 words in length and contain no more than one figure or table.


Covering Letter

All manuscripts must be accompanied by a signed cover letter in the “Comments for the Editor” and submitted by the Corresponding Author during online submission. Other than any comments, you would like to write to the editor, the following items must be addressed in this letter; importance of the work and its relevance to the journal’s scope, the name, address, telephone number, fax number, and e-mail address of the Corresponding Author. The author has to confirm in written that the manuscript (or any parts of it) has not been published previously or is not under consideration for publication in another journal. Previous presentation in any congresses should be stated in the covering letter. You are also required to mention the names of two potential preferred referees that could be considered for reviewing your manuscript.



Highlights are required for this journal. They consist of a short collection of bullet points that convey the core findings of the manuscript, including 3 to 5 bullet points (maximum 85 characters, including spaces, per bullet point), and should be submitted in a separate page following the Title page.


Graphical Abstract

A colored graphic could be included with each manuscript. This must be presented in a separate page following the Abstract (preferred file types are TIFF, PNG, JPEG and Power Point, minimum 300 dpi). A graphical abstract, not exceeding 30 words along with the illustration, helps to summarize the contents of the manuscript in a concise pictorial form.

- Keywords

Author(s) should provide 4 to 6 keywords, which can be used for indexing purposes. They should be in alphabetic order and first capital letter, separated with semicolons.

- Abbreviations (if required)

The full term of each abbreviation should be written in the text before its first use. Standard and well-known abbreviations do not need explanation. All nomenclature, including gene names and symbols, should be used in a scientifically accurate manner following the nomenclature conventions adopted by the scientific community.

- Main text

When submitting a manuscript, ensure that the following sections are included separately; Introduction, Materials and Methods, Results and Discussion, Conclusion, Acknowledgements, Competing Interests and References. Introduction should be concise, without subheadings and indicates the purpose and rational of the study. Materials and Methods provide sufficient detail to allow the work to be reproduced, with details of supplier and catalogue number when appropriate. Methods already published should be indicated by a reference, only relevant modifications should be described. Discussion should explore the significance of the results of the work, not repeat them. It may contain subheadings in some sections. The detailed data should not be repeated again in Conclusion. In the case of Short Communications, Result and Discussion and Conclusion could be merged.

- Acknowledgements

 All contributors who do not meet the criteria for authorship should be covered in this section. Financial and material supports should also be acknowledged.

- Competing Interests

 Author(s) warrant that any financial interests, direct or indirect, that exist or may be perceived to exist for individual contributors in connection with this manuscript have been disclosed in the Covering Letter and Manuscript.

- References

All references should be listed accordance to the Harvard style. Harvard is an 'author/date' system, so your in-text citation consists of author(s) and year of publication. At the end, the authors should be listed in alphabetical order. For more guides, use the online information at
