Open Field Test
Objective: To measure locomotor activity and exploratory behavior in mice by recording distance traveled and freezing behavior in an open field arena
This is a Open Field Test protocol using Mouse as the model organism. The procedure involves 3 procedural steps, 2 equipment items, 2 materials. Extracted from a 2025 paper published in Mol Ther Nucleic Acids.
Model and subjects
Mouse • Atn1 Q112/+ mice • Not specified • Not specified • Not specified
Study window
~12 minutes hands-on
Core workflow
Place mouse in arena center • Record video session • Analyze video data
Primary readouts
- Total distance traveled
- Freezing to motion ratio
Key equipment and reagents
Use this page as an execution guide, then fall back to the source paper whenever you need exact exclusions, dosing details, or assay-specific caveats.
Confirm first
- Verify the animal model, intervention setup, and collection timepoints against the source paper.
- Check that every direct vendor link matches the exact specification your lab plans to run.
Use the page like this
- Work through the protocol steps in order and use the inline vendor chips only when you need to source or verify an item.
- Jump to Experimental Context for readouts, data shape, and analysis flow before planning downstream analysis.
