Can the CCK-8 assay stain living cells?

Publication date:2026-10-29

No. This is because the main component of CCK‑8 is a water‑soluble tetrazolium salt (WST‑8), which, via the electron carrier PMS, transfers electrons from living cells to WST‑8 in the culture medium. Since the formazan product formed is also highly water‑soluble, CCK‑8 cannot be used to stain cells.
