Hunted through Prism's Analyze menu for ANCOVA? It isn't there, and GraphPad's own FAQ confirms they've never shipped one. Prism can still do it, through two documented routes most users never find: the simple-linear-regression slopes test for the parallel-slopes assumption, and multiple regression with dummy-coded groups for the adjusted comparison. Here are both step by step, plus an honest comparison with describing the same analysis in plain language instead.

An audit of 200 published animal studies found only 22% had replicated the right thing, and 46% counted repeated measurements of one biological unit as independent samples. That error, pseudoreplication, inflates your n, shrinks your error bars, and manufactures significance that won't replicate. Here's what separates technical vs biological replicates, why the mistake inflates false positives, and what actually counts as a biological replicate in cell culture.

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

You asked to get CytCut onto your bench now instead of waiting, so here it is. CytCut 3.5 is available for immediate order at $36, in 24- and 48-well, the same wound healing assay tool that turns minutes of pipette scratching into seconds of consistent, reproducible wounds. It's UV- and alcohol-sanitizable with a 3–6 month working life. The autoclavable CytCut 4.0 is still on track for end of September at $99 pre-order. Order 3.5 with code cytcut352673 for $15 off through Jul
