Primary Assay — Drosophila
RING / Negative Geotaxis (Climbing Assay)
Drosophila melanogaster
Flies are tapped to the bottom of a vial and their climbing ability is recorded. The Rapid Iterative Negative Geotaxis (RING) assay enables high-throughput quantification. Sensitive to aging and neurodegeneration.

Quantitative Output
Measured Parameters
Every parameter is automatically tracked frame-by-frame in the ConductVision pipeline for Drosophila melanogaster.
| Parameter | Unit | Description |
|---|---|---|
| Climb height at 4s | cm | Distance climbed in fixed time |
| % reaching top | % | Proportion clearing the vial |
| Climb speed | cm/s | Average upward velocity |
| Performance index | score | Composite of height and proportion |
