CCK-8 Cell Counting Kit

Overview

CCK-8 Cell Counting Kit is a research-use kit supporting cell proliferation assay workflows. The amount of formazan dye generated by dehydrogenases in living cells is directly proportional to the number of living cells. Key notes from the supplied features include: Low cytotoxicity, high sensitivity, and good repeatabilityComponents. The wording is kept close to the supplied product information, helping you reference the right item quickly and document consistently.

Key Benefits

• Ready-to-use reagentReliable performance: Low cytotoxicity, high sensitivity, and good repeatabilityComponents for cell proliferation assay documentation and method consistency.
• The amount of formazan dye generated by dehydrogenases in living cells is directly proportional to the number of living cells.
• The measurements can indirectly show the number of living cells.
• Clear, structured description for faster review and fewer purchasing errors.

How it supports your workflow

In day-to-day research, teams often need products that fit existing methods while remaining easy to justify in notes, SOPs, and reporting. For cell proliferation assay workflows, the goal is often to keep the scientific rationale and the purchasing record aligned. CCK-8 Cell Counting Kit is based on WST-8 [2- (2-methoxy-4-nitrophenyl)-3- (4-nitrophenyl)-5- (2,4-disulfophenyl)-2H-tetrazolium, monosodium salt] that is rapidly absorbing, highly sensitive and widely used in detection of cell proliferation and cytotoxicity. The amount of formazan dye generated by dehydrogenases in living cells is directly proportional to the number of living cells. The measurements can indirectly show the number of living cells. The supplied feature set highlights ready-to-use reagentreliable performance, which can help teams standardize language and expectations across similar products. Because projects evolve, we aim for descriptions that remain searchable, specific, and easy to compare across catalog numbers—so you can reorder confidently and keep documentation consistent.

Applications & compatibility

Use the notes below to gauge fit for your setup and documentation needs. Based on the supplied information, it’s positioned for cell proliferation assay workflows where clear documentation and straightforward compatibility notes matter. If you’re matching this item to an established SOP, use the product name, catalog number, and the supplied features as the primary reference points. Use the application notes as a scope guide: they indicate fit and compatibility language drawn from the supplied product information, not assumptions beyond it.

Ideal for: labs focused on cell proliferation assay workflows; teams that need clear, searchable documentation for purchasing and experimental records; and groups standardizing methods across projects or sites. Ideal when you need a quick, confident match between what’s on the page and what’s in your records.
