Description

Application

20-Hydroxyecdysone has been used:

• in Leibovitz′s dissecting medium for culturing sorting zone and neuropil-associated glia and antennal lobes of Manduca sexta
• in Schneider′s medium to reproduce ex-vivo imaginal disc eversion
• as a supplement in Mcl8 medium for culturing Drosophila wing imaginal discs

Biochem/physiol Actions

20-Hydroxyecdysone is an ecdysteroid hormone that plays a key role in insect development, cell proliferaton, growth and apoptosis by controlling gene expression involved in molting and metamorphosis. It acts through a heterodimeric receptor comprising the ecdysone receptor and the ultraspiracle proteins (USP).
