Description & Advantages

Cell Counting Kit-8 (CCK-8) allows sensitive colorimetric assays for the determination of cell viability in cell proliferation and cytotoxicity assays.

Application

CCK-8 can be used to assess cell proliferation induced by cytokines and other stimulants, as well as to evaluate cytotoxicity caused by anticancer drugs or other toxic agents. It is also applicable for detecting cell growth inhibition induced by various compounds.

Storage

4°C, 2 years

Keep away from light for long-term storage.

Attention

1. Since the CCK-8 assay is based on the dehydrogenase activity detection in viable cells, conditions or chemicals that affect dehydrogenase activity in viable cells may cause discrepancy between the actual viable cell number and the cell number determined using the CCK-8 assay.

2. WST-8 may react with reducing agents to generate WST-8 formazan. Please check the background O.D. if reducing agents are used in cytotoxicity assays or cell proliferation assays.

3. Be careful not to introduce bubbles to the wells, since they interfere with the O.D. reading.

4. If the sterilization of the CCK-8 solution is necessary, please filter the solution with a 0.2 μm membrane.

5. The incubation time varies by the type and number of cells in a well. Generally, leukocytes give weak coloration, thus a long incubation time (up to 4 hours) or a large number of cells (~105 cells/well) may be necessary.

6. Measure and subtract the O.D. at 600 nm or higher from that of sample if there is a high turbidity in the cell suspension.

7. This product is for R&D use only, not for drug, household, or other uses.

8. For your safety and health, please wear a lab coat and disposable gloves to operate.
