The International Journal of Peptide and Protein Research ran from 1972 to 1995. See its scope, successor journal, and impact factor history.
The International Journal of Peptide and Protein Research was a peer-reviewed scientific journal that published peptide synthesis, protein chemistry, and structural biology research from 1972 to 1995. It was issued by Munksgaard in Copenhagen and is continued today by the Journal of Peptide Science, published by Wiley on behalf of the European Peptide Society. Because the title stopped publishing in 1995, it has no current impact factor and does not accept new submissions.
What the Journal Covered
The journal's scope reflected the methods of its era: amino acid analysis, sequencing, solid-phase peptide synthesis, spectroscopy, and the physical chemistry of proteins. Papers were written for working scientists, not a general audience, and most ran several pages of experimental detail.
Common subject areas included:
- Solution and solid-phase peptide synthesis, including protecting-group chemistry
- Protein sequencing, purification, and characterization
- Conformational analysis by NMR, circular dichroism, and X-ray methods
- Structure–activity relationships in biologically active peptides
- Enzymology and protein–ligand interactions
That mix made the title a standard reference for peptide and protein research in the 1970s and 1980s, when techniques now taken for granted were still being worked out in individual labs.
Key Facts at a Glance
| Detail | Information |
|---|---|
| Field | Peptide chemistry, protein chemistry, biochemistry |
| Publisher | Munksgaard, Copenhagen (later part of the Wiley portfolio) |
| Active years | 1972–1995 |
| ISSN | 0367-8377 |
| Frequency | Monthly issues, usually grouped into several volumes per year |
| Successor title | Journal of Peptide Science (Wiley, launched 1995) |
| Current impact factor | None — the journal is no longer published |
| Indexing | Records for many volumes appear in MEDLINE/PubMed and other life-science databases |
In older bibliographies, a citation to "Int. J. Pept. Protein Res." refers to this journal. Search results often render the name without the word "and" — as international journal of peptide protein research — or with an ampersand in place of the conjunction, but every version points to the same 1972–1995 title.
Does It Have an Impact Factor?
The International Journal of Peptide and Protein Research impact factor is a frequent search because the journal appears in reference lists that are decades old. The title did receive impact factors during its publication years, but those figures are historical and are not comparable to metrics reported for active journals today.
Journal Citation Reports does not assign an impact factor to a journal that has ceased publication. Any "current" number attached to this name online should therefore be treated with caution. If you need a live metric, look at the successor and neighboring titles instead:
- Journal of Peptide Science — the direct continuation, whose impact factor has hovered near 2 in recent years.
- International Journal of Peptide Research and Therapeutics — a separate, still-active Springer publication.
- Peptide Science — Wiley's active peptide-focused journal, formerly the peptide section of Biopolymers.
Impact factors change every June, so always confirm the newest number on the publisher's site or in the current Journal Citation Reports.
Where to Find Articles and Back Issues
Back volumes are widely available, though rarely all in one place. These routes work well for most readers:
- Publisher archives: the digitized run is hosted on Wiley Online Library, which also carries the successor journal.
- Databases: MEDLINE/PubMed and Web of Science include records for many articles; abstracts are often free even when the full text is paywalled.
- Libraries: university and hospital libraries frequently hold the print volumes, and interlibrary loan can supply scans of individual papers.
- Citation trails: Google Scholar will point you to newer articles that cite the original work.
For any paper published before 1995, the fastest approach is usually to search the exact article title in a database and then follow the "cited by" links forward.
Similar Journal Names That Cause Confusion
Several active titles use nearly identical wording, which is why students sometimes land here while looking for the journal of peptide research and therapeutics. Checking the ISSN before citing anything saves a lot of time.
| Title | Publisher | Status | Notes |
|---|---|---|---|
| International Journal of Peptide and Protein Research | Munksgaard | Ceased in 1995 | ISSN 0367-8377; continued by the Journal of Peptide Science |
| Journal of Peptide Science | Wiley (European Peptide Society) | Active | Direct successor; peptide chemistry and biology |
| International Journal of Peptide Research and Therapeutics | Springer | Active | Different journal; formerly Letters in Peptide Science |
| Peptide Science | Wiley | Active | Peptide structure, function, and applications |
| Current Topics in Peptide and Protein Research | Book series | Ongoing | Volume-by-volume reviews rather than a monthly journal |
Why the Archive Still Matters Today
Much of the vocabulary used in modern peptide work — resin loading, coupling efficiency, sequence analysis — was formalized in journals like this one. Reviewers writing in current topics in peptide and protein research still cite those early papers, and the archive remains a practical source of detailed synthetic procedures.
The legacy also shows up in industry. A peptide research and development team may pull a synthesis protocol from a 1980 volume, and a peptide research company benchmarking methods will often trace a technique back to its first published description. The same applies to commercial scale-up, where the peptide research supply chain for reagents and resins grew out of methods first reported in these pages.
Papers in the archive describe laboratory reagents and experimental models. They are not clinical guidance, and no compound discussed in them should be assumed safe or effective for human use.
Peptides sold for laboratory work are research chemicals, not FDA-approved medicines. Anyone considering a peptide for personal use should speak with a licensed healthcare professional rather than relying on journal articles written for chemists.
Frequently Asked Questions
Is the International Journal of Peptide and Protein Research still published?
No. The journal published its final volumes in 1995 and was continued by the Journal of Peptide Science, which Wiley publishes for the European Peptide Society. The original title no longer accepts submissions and has no editorial board.
What is the impact factor of the International Journal of Peptide and Protein Research?
There is no current impact factor, because Journal Citation Reports does not rank journals that have ceased publication. The title had impact factors during its 1972–1995 run, but those numbers are historical. For a live metric, check the successor Journal of Peptide Science, which has recently reported a figure near 2.
How can I access old International Journal of Peptide and Protein Research articles?
Digitized back volumes are available through Wiley Online Library, and abstracts for many papers appear in MEDLINE/PubMed and Web of Science. University and hospital libraries often hold the print run, and interlibrary loan can provide scans of specific articles.
