A no-fluff, step-by-step cell imaging protocol for microscopy images you can actually quantify. Eighteen numbered steps take you from Köhler setup and pixel calibration, through setting exposure on your brightest sample so nothing saturates, to acquiring the whole set under locked, identical settings. Works for brightfield, phase contrast, and fluorescence. Includes an equipment table, an acceptance-criteria checklist, and a troubleshooting table mapping each symptom to the s

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.

Koehler illumination is the gold-standard technique for achieving perfectly even, high-contrast, and artifact-free images. But mastering it can seem intimidating. This definitive guide demystifies the process, breaking down the complex theory of conjugate planes and providing a simple, 6-step practical protocol. Stop fighting glare and uneven light. Follow these steps to unlock your microscope's true potential.
