Social Interaction Test
Objective: Measurement of social behavior and interaction between mice
This is a Social Interaction Test protocol using mouse as the model organism. The procedure involves 5 procedural steps, 2 equipment items, 2 materials. Extracted from a 2016 paper published in Molecular Brain.

Study window
~1 day study window
Core workflow
Animal transport and acclimation • Housing conditions • Test battery order
Primary readouts
- Social behavior measurements
- Social interaction between mice
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.
Protocol Steps

Animal transport and acclimation
Genetically engineered mice and wild-type control mice were transported from animal facilities of other laboratories or vendors to the laboratory
Note: Mice were transported from external sources

“Genetically engineered mice and their wild-type control mice were transported from the animal facilities of other laboratories or vendors to our laboratory”
Housing conditions
Mice were housed in plastic cages with sterilized PaperClean Bedding under a 12-hour light/dark cycle with lights on at 7:00 am, with ad libitum access to food and water
Note: Housing density varied: 1.3% with 1 animal, 2.3% with 2 animals, 6.7% with 3 animals, 80.1% with 4 animals, 8.9% with 5 animals, and 0.7% with 6 animals per cage at the beginning of test battery

Test battery order
Mice were subjected to a behavioral test battery in a standardized order. Social interaction test was performed after elevated plus maze and hot plate tests, and before rotarod test
Note: Behavioral testing was performed between 9:00 a.m. and 6:00 p.m. Interval between tests was at least 1 day. More than 75% of mice were tested in accordance with the standard order, though some strains had tests omitted or reordered
View evidence from paper
“The mice were generally tested in the following order; general health and neurological screening, light/dark transition, open field, elevated plus maze, hot plate, social interaction, rotarod, startle response/prepulse inhibition, Porsolt forced swim, Barnes maze, contextual and cued fear conditioning, and tail suspension tests. The interval between tests was at least 1 day.”
Social interaction test
Social interaction test was performed as part of the behavioral test battery to measure social behavior and interaction between mice
Note: Specific details about the social interaction test procedure are not provided in this methods section

Apparatus cleaning
After all tests, apparatus were cleaned with super hypochlorous water and 70% ethanol to prevent bias due to olfactory cues
Note: Cleaning was performed between tests to eliminate olfactory cues
