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 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

Your p-value can confirm an effect is real and say nothing about whether it's big enough to matter. Effect size answers that second question, and for a two-group comparison Cohen's d is the standard measure: the mean difference divided by the pooled standard deviation. This guide covers how to calculate and report Cohen's d, why to report it alongside every p-value and confidence interval, and how to interpret it without leaning on the 0.2/0.5/0.8 benchmarks that often don't

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.

Unlock the power of crystal violet staining! This comprehensive, step-by-step Standard Operating Procedure (SOP) demystifies the widely-used technique for quantifying adherent cell numbers. From cell seeding and fixation to precise staining, washing, and solubilization, each phase is detailed for accuracy. Learn to troubleshoot common issues and ensure reliable, reproducible results for your cell viability, proliferation, or cytotoxicity assays.
