Description

KL201 a circadian clock modulator, is a isoform-selective cryptochrome 1 (CRY1) stabilizer. KL201 has no stabilizing effect on CRY2. KL201 lengthens the period of circadian rhythms in cells and tissues[1].

In Vitro

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].

In Vivo:

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.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    90% Corn Oil

    Solubility: ≥ 2.08 mg/mL (5.36 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 900 μL Corn oil, and mix evenly.

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.
