CRY2 |
KL201 causes dose-dependent lengthening of circadian period in Bmal1-dLuc reporter cells, and in cells with another circadian reporter Per2-dLuc. KL201 suppresses the intensity of Per2-dLuc reporter much more than that of Bmal1-dLuc, without affecting cellular viability[1].
KL201 binds to CRY1 in overlap with FBXL3, a subunit of ubiquitin ligase complex, and the effect of KL201 is blunted by knockdown of FBXL3[1].
KL201 lengthened circadian period and suppressed the intensity of Per2::Luc knockin reporter in mouse lung primary explants[1].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
