Flow-Cytometry Panel Version Control (GMP / 21 CFR Part 11)

Git-style version control for flow-cytometry panels — track every revision, change summary, author and sign-off, tuned for a GMP-regulated lab. Private and offline.

Keep an immutable, dated history of every flow-cytometry panel — each version records what changed, who changed it and its sign-off status. Built for cytometry cores who need an immutable, sign-off-controlled audit trail. Nothing leaves your browser, so even unpublished methods stay confidential.

Tip: bump the minor version (v1.1 → v1.2) for small edits and the major version (v2.0) for changes that affect results. Export to CSV for your QMS or an audit.

No versions yet. Log v1.0 of your first flow-cytometry panel above — every later edit becomes a new, dated, attributable version.

Free flow-cytometry panel version control and change-log for a GMP-regulated lab: track revisions, sign-offs and an audit trail entirely in your browser.

About Flow-Cytometry Panel Version Control (GMP / 21 CFR Part 11)

A free, offline flow-cytometry panel version-control tool for cytometry cores. Keep an immutable, dated history of every flow-cytometry panel — each version records what changed, who changed it and its sign-off status. Built for cytometry cores who need an immutable, sign-off-controlled audit trail. Nothing leaves your browser, so even unpublished methods stay confidential.

How to use Flow-Cytometry Panel Version Control (GMP / 21 CFR Part 11)

  1. 1Add v1.0 of your flow-cytometry panel with a short description of the method (e.g. a multicolor antibody panel).
  2. 2Each time you change it, log a new version with a change summary, your name and the date — never overwrite the old one.
  3. 3Set the status as it moves through Draft / QA review / Approved / Effective / Retired, and export the full history to CSV for your records or QMS.

Why use Flow-Cytometry Panel Version Control (GMP / 21 CFR Part 11)?

  • ✓Flow-Cytometry Panels evolve constantly — this gives cytometry cores a Git-style history so you always know which version produced which result.
  • ✓Each entry captures a change summary, author, date and sign-off status (Draft → QA review → Approved…), giving a GMP-regulated lab an immutable, sign-off-controlled audit trail.
  • ✓Supports a Part-11-style mindset: dated, attributable, never-overwritten records you can export for an inspector.

Frequently asked questions

Why use version control for a flow-cytometry panel?+

Methods drift over time, and a result is only reproducible if you know exactly which version of the flow-cytometry panel produced it. Version control gives every revision a number, a change summary and an author, so you can reproduce old work, justify changes to reviewers, and onboard new cytometry cores without losing institutional knowledge.

How should I number protocol versions?+

A simple semver-style scheme works well: bump the minor number (v1.1 → v1.2) for small edits like a reagent swap, and the major number (v1.x → v2.0) for changes that could affect results, such as a new incubation time or instrument. Record the rationale in the change summary so the jump is self-explanatory at audit.

Is this an electronic lab notebook (ELN)?+

It is a lightweight, offline version-control log rather than a full ELN — but it captures the part that matters most for reproducibility: a dated, attributable, immutable history of every change to a flow-cytometry panel. You can export to CSV and attach it to your ELN or QMS at any time.

Where is my data stored?+

Entirely in your browser's localStorage — no sign-up, no upload, no server. That keeps proprietary methods and unpublished IP private and means the tool works offline, which is exactly what a GMP-regulated lab needs.
