Muristerone A (2beta,3beta,5beta,11alpha,14alpha,20R,22R-Heptahydroxycholest-7-en-6-one)
|Biochemicals||Storage: 4°C/-20°CShipping: Blue Ice|
Muristerone A is a potent member of the ecdysteroid family. Ecdysone receptor (EcR) agonist. An analog of ecdysone with similar properties to Ponasterone A. Inducer of ecdysone-inducible gene expression systems in mammalian cells and transgenic animals.
Induces apoptosis in cells transfected with wild-type Bax. Induces expression of beta-galactosidase. Stimulates Bcl-XL mRNA transcription and inhibits TRAIL- and hFasL-induced apoptosis in RKO cells. Insect steroid hormone involved in regulating metamorphosis, causing a response to G2 cell cycle arrest. Major molting hormone in some insects. Has protective effects in plants.
Storage and Stability:
Lyophilized powder may be stored at -20°C. Stable for 12 months at -20°C. Reconstitute with sterile buffer or dH2O. Aliquot to avoid repeated freezing and thawing. Store at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
