Product Information
| Description: | Helenalin is an anti-inflammatory sesquiterpene lactone, it selectively inhibits transcription factor NF-κB by directly targeting p65. Helenalin effectively inhibits C/EBPβ at least 10 times higher than that for NF-κB (EC50 values were determined between 0.1 and 0.4 μM for C/EBPβ). |
| 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. |
