Ponasterone A is a member of the ecdysteroid family. Ecdysone receptor (EcR) agonist. An analog of ecdysone with similar properties to muristerone A. Induces expression of b-galactosidase to levels similar to those obtained with muristerone A induction. Potent compound for ecdysteroid activity. Insect steroid hormone involved in regulating metamorphosis. Solubility: DMSO, EtOH Molecular Weight: ~464.63 Storage and Stability: Lyophilized powder may be stored at -20 degrees C. Stable for 12 months at -20 degrees C. Reconstitute with sterile buffer or dH2O. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees 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.
