A no-fluff, step-by-step scratch assay imaging protocol for images your software can actually measure. Twenty-six numbered steps take you from pixel calibration and Köhler alignment, through Time 0 capture with locked exposure, to returning to identical fields at later time points. Includes an equipment table, an acceptance-criteria checklist to run before you analyze, and a troubleshooting table mapping every common symptom to the step that fixes it.

A perfect scratch becomes unusable if the field drifts out of focus, the illumination shifts between time points, or the wound edges are too low-contrast to segment. The biggest scratch assay imaging mistakes aren't dramatic failures, they're small inconsistencies that quietly distort wound area. This guide covers the imaging principles behind reproducible wound healing assays on any microscope: imaging mode, objectives, Köhler illumination, and locking your optics.

Yes, you can run an MTT assay on suspension cells, but don't dump the media! You risk losing your sample. Learn the two critical methods—Centrifugation vs. Direct Solubilization—to ensure accurate viability data without washing your cells down the drain.
