CytoChron
Beta

Track cell cultures from experiment to freezer and back.

CytoChron is a cell culture tracker for research labs. Keep each culture's current state, history, protocols and frozen-vial lineage connected in one workspace.

Know what a culture is now, and how it got there.

Every culture has a Current State: passage, confluency, medium, vessel, coating and differentiation stage. Its Timeline holds a dated history of media changes, passages, observations, freezes and other biological actions, alongside what is planned next.

Actions with defined state effects update Current State when completed, keeping history and state connected. Each day also shows what is due or overdue.

Write a protocol once. Run it on real cultures.

Plan a protocol day by day, with instructions, checklists and repeating actions. Apply it to a culture and its steps appear on real calendar dates.

A step can carry explicit Current State effects, such as setting the differentiation stage on Day 12. Editing the template later does not change protocols already applied, so their history stays accurate.

Frozen stocks stay connected to the cultures they came from.

Freeze straight from a tracked culture: choose the storage positions, create one vial or several, and each vial keeps the culture's passage, stage and medium at the time of freezing.

Search stored vials and move them when the freezer is reorganized. Thaw a vial into a new tracked culture and the lineage is kept in both directions.

Freezers and LN2 tanks, racks, canes and flexible box layouts. CytoChron tracks stored cell vials, not reagents or equipment.

The experiment does not live in one person's notebook.

Keep your own work in a Personal workspace. For lab work, create a shared workspace and invite colleagues, so projects, cultures, protocols and the Cell Bank stay organized in one place the whole lab can follow.

Owners manage members, Editors record work, and Viewers can read without changing anything.

Made for culture work that runs for weeks: iPSC maintenance and differentiation, organoids, derived cell types, shared lab cultures and biobanks.
