Product Information
| Description: | SEC inhibitor KL-1 (KL-1) is a potent and selective inhibitor of super elongation complex (SEC) that disrupts the interaction between the SEC scaffolding protein AFF4 and P-TEFb, resulting in impaired release of Pol II from promoter-proximal pause sites and a reduced average rate of processive transcription elongation. KL-1 exhibits an dose-dependent inhibitory effect on AFF4-CCNT1 interaction with Ki of 3.48 μM. |
| Stability and Solubility Advice: | Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide. We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vials and used within 1 month. Avoid repeated freeze and thaw cycles. Storage conditions for some special products should refer to their storage details. |
