Technical Support

CHK1-IN-3 is a potent and selective CHK1 inhibitor with an IC₅₀ of 0.4 nM. CHK1-IN-3 effectively inhibits the growth of malignant hematopathy cell lines and displays low affinity for hERG (IC₅₀ > 40 μM). CHK1-IN-3 significantly suppresses the tumor growth in vivo. CHK1-IN-3 can be used for the study of hematologic malignancies.

For research use only. We do not sell to patients.

Help & FAQs

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
