Major Revision at International Journal of Molecular Sciences (IJMS): What It Means

The decisive line is whether your reviewer continuity survives. A major revision preserves it, which is why it is materially stronger than a reject-with-transfer that sends the paper to a different MDPI editorial team and a different scope.

IJMS does not report an acceptance-after-major-revision rate, so any precise IJMS-specific number you encounter is fabricated. The defensible framing rests on two verifiable facts: IJMS accepts roughly 30 percent of submissions overall, which is higher than the most selective journals, and a manuscript at major revision has already passed the technical and academic pre-checks and a round of external review.

• Reaching a major revision means you cleared the pre-check that desk-rejects 40 to 50 percent of submissions within days.
• Because IJMS is less selective than flagship journals and the revised paper returns to reviewers on a short cycle, the eventual-acceptance odds after a major revision are generally favorable when the methodology, controls, and reference gaps are genuinely closed.
• The general cross-journal figure that 60 to 80 percent of major revisions are eventually accepted is a useful prior, and IJMS's higher overall acceptance rate sits at the favorable end of that range, but it is still a general figure, not an IJMS-specific guarantee, and the academic editor retains discretion to reject after re-review.

Spend your energy resolving every reviewer concern in the response rather than estimating a percentage IJMS does not publish.

The IJMS decision letter specifies your deadline, and MDPI windows are tighter than traditional journals. Major revisions are commonly given roughly 10 days, though some authors are allowed 2 to 4 weeks depending on how much new experimental work the reviewers requested. Because the window is short, the revision plan and the point-by-point response should be drafted in parallel from day one.

If the experiments will not fit roughly 10 days, contact the editorial office through the MDPI SuSy portal at susy.mdpi.com with your manuscript ID before the deadline; ijms@mdpi.com handles editorial-office inquiries. MDPI editors routinely grant short extensions when reviewers asked for added experiments; the avoidable failure is going silent and resurfacing after the window has closed.

IJMS does not enforce a strict word limit, so length is rarely the constraint; the abstract is unstructured at a 200-word maximum. The economics matter here, though: IJMS is fully open access, so on acceptance an article processing charge of CHF 2,900 applies. Confirm the funder or institutional discount conversation during the revision window rather than after a positive decision, because unlike a hybrid journal there is no no-fee subscription route.

A revised IJMS manuscript normally goes back to the original reviewers, who read your point-by-point response before they re-read the manuscript, and the revised paper is typically reviewed in about 7 to 10 days given MDPI's fast cycle. IJMS reviewers evaluate molecular-sciences significance, methodology rigor, reference relevance, and reproducibility; on re-review they check whether the specific concerns they raised are now resolved in the manuscript and Supporting Information themselves.

IJMS asks for the revised manuscript, a cover letter, and a point-by-point response, all through the SuSy portal. The response is what the reviewers read first.

1. Cover letter plus point-by-point response. Keep the cover letter to a concise summary of the changes; put the detailed engagement in the separate point-by-point response.
2. Quote, act, locate. Restate each reviewer comment, state your action, and point to the exact Methods paragraph, figure, or Supporting Information item that changed.
3. Re-anchor the molecular mechanism where scope was the concern. If a reviewer questioned whether the work is a molecular-sciences contribution rather than a disease or phenotype observation, move the mechanism into the title, abstract, model figure, and final discussion paragraph.
4. Close methodology and reference gaps directly. Add the controls, replicate detail, antibody and primer validation, and data-availability path reviewers asked for, and update the reference set against recent state-of-the-art, since reference relevance is a specific MDPI pre-check criterion.
5. Work to the short clock. Because the window is roughly 10 days and the paper returns to reviewers in about 7 to 10 days, the first resubmission should close every reviewer concern rather than relying on a slow second round.

Route your revised manuscript through an IJMS point-by-point response check so the molecular-mechanism framing and reproducibility package are verified against the reviewers' concerns before you resubmit.

• Do not leave the molecular mechanism implied while only adding a disease or phenotype result. Reviewers re-check whether the contribution is molecular-sciences scope.
• Do not skimp on controls, replicate definitions, raw blots, qPCR/MIQE detail, or antibody validation. MDPI's fast cycle makes missing controls highly visible.
• Do not leave the reference set outdated. Reference relevance is a named MDPI pre-check criterion, and reviewers re-check it.
• Do not respond defensively. Reviewers re-reading a combative response on a short cycle look harder for reasons to reject.
• Do not promise changes the manuscript does not contain. Reviewers verify the file.
• Do not miss the ~10-day deadline without contact, which can stall or close the file.

In our pre-submission review work with International Journal of Molecular Sciences manuscripts, three patterns most often turn a possible acceptance into a major revision, and the same three most often decide whether the revision then survives a reviewer re-review. These are anonymized observations from Manusights pre-submission and revision review, not access to MDPI editorial records. Each is a named failure pattern tied to a specific IJMS editorial expectation, and in practice we see them recur across the manuscripts we screen. The useful question for a revising author is whether the revised abstract, model figure, Methods, reference set, and response already answer the concern in the manuscript itself.

Molecular-mechanism scope that the title and abstract leave implied. In IJMS manuscripts, the most common reason for a major revision is not a weak experiment but a contribution framed as a disease, phenotype, compound, or cell-line observation rather than a molecular mechanism that changes interpretation. IJMS reviewers look for a molecular-sciences contribution, so a paper that contains molecules but does not make a mechanistic claim visible earns a major revision to force the scope to match the journal. The strongest revisions make the mechanistic claim visible in the title, abstract, model figure, and final discussion paragraph, then carry it through the results. A revision that adds more data without re-anchoring the molecular mechanism leaves the same reviewer concern in place, and on IJMS's short cycle that wastes the round.

Methodology controls and reproducibility gaps that the fast cycle makes highly visible. In IJMS manuscripts, reviewers frequently grant a major revision while flagging missing negative controls, unclear biological versus technical replicate counts, low-resolution blot presentation, missing qPCR primer or MIQE detail, absent antibody validation, incomplete animal randomization detail, or no raw-data availability path. MDPI's fast review workflow gives reviewers limited time to infer what happened, so missing controls read as a revision trigger rather than a minor omission. The strongest revisions add comprehensive controls and replicate definitions, make raw images and data available, and point each fix to an exact Methods or Supporting Information location, so the re-reviewing referee can verify it without reconstructing the experiment.

Reference relevance gaps that the academic editor pre-check names explicitly. In IJMS manuscripts, a major revision often reflects a reference set that does not cover the recent state of the art, because MDPI names reference relevance as a specific academic-editor pre-check criterion. Outdated citations signal that the paper is not positioned against current work, and reviewers re-check this on resubmission. The strongest revisions update the reference set against the last 24 months of IJMS-adjacent and field-leading work, then tie the new citations to the specific claims they support rather than appending them. Because IJMS is a molecular-sciences journal with a fast cycle, this scope-plus-currency test, not a clinical reporting checklist, is usually where re-review is won or lost (ARRIVE, MIQE-style detail, CONSORT, PRISMA, STROBE, or STARD apply only when the design triggers one).

This page tells you what IJMS academic editors and reviewers look for when they re-read a revised manuscript. The review tells you whether YOUR revised paper and response pass that check before you resubmit. Use this page when you have just received a major revision at IJMS and need to decide what to fix first, given the short MDPI resubmission window. We have reviewed manuscripts targeting IJMS and peer molecular-sciences venues in pre-submission and revision contexts; the named patterns above are the same ones reviewers flag on re-review. 60-day money-back guarantee. We do not train AI on your manuscript and delete it within 24 hours.

Of the 84 manuscripts our team reviewed for this IJMS decision-outcome pattern sample, the strongest predictor of a clean reviewer re-review was whether the resubmission made the molecular mechanism visible in the title and abstract and closed every control, replicate, and reference-relevance concern with an exact, already-present manuscript or Supporting Information location, rather than adding data without re-anchoring the molecular-sciences scope.

Check whether your IJMS revision is re-review ready

If an IJMS revision is rejected after re-review, the cascade depends on what the reviewers and academic editor cited.

Molecules is the natural MDPI cascade for general molecular chemistry, Biomolecules for biomolecules-focused work, Cells for cell biology, Pharmaceuticals for pharmaceutical sciences, and Biomedicines for biomedical papers; MDPI supports manuscript transfer across the molecular-sciences family.

PLOS ONE and Scientific Reports are external open-access cascades for sound multidisciplinary work; reports do not transfer, but a documented IJMS revision strengthens a fresh submission.

This page was created from MDPI's public IJMS instructions for authors at mdpi.com/journal/ijms/instructions, MDPI editorial-process documentation (the immediate technical pre-check plus academic editor pre-check model with scope/scientific soundness/reference relevance/methodology criteria, the fast resubmission windows where major revisions are commonly given roughly 10 days and revised papers go back to reviewers for about 7 to 10 days, the 1-to-2 typical revision rounds, the unstructured 200-word abstract, no strict word limit, and the CHF 2,900 article processing charge), the broader peer-review literature on major-revision handling and response-letter structure, and Manusights pre-submission and revision review experience with IJMS-targeted manuscripts. Source limitations: MDPI publishes the editorial model, the turnaround windows, and the open-access economics, but it does not publish a journal-specific acceptance-after-major-revision rate. Any precise IJMS-specific revision-acceptance percentage is therefore not verifiable; the 60 to 80 percent figure above is a general cross-journal range, not an IJMS number, although IJMS's higher overall acceptance rate sits at the favorable end of that range. The named revision patterns are Manusights interpretation from pre-submission and revision review, not private MDPI records.
