Makisterone A (2beta,3beta,14alpha,20R,22R,25-Hexahydroxy-5beta-24R-ergost-7-en-6-one)

\nA member of the ecdysteroid family.\n Ecdysone receptor (EcR) agonist. \nInduces the expression of genes coding for proteins that the larva requires, and it causes chromosome puffs (sites of high expression) to form in polytene chromosomes. \nPlays a role in insect development, cell proliferaton, growth and apoptosis by controlling gene expression involved in moulting and metamorphosis. It acts through a heterodimeric receptor comprising the ecdysone receptor and the ultraspiracle proteins (USP).\n Appears in plants mostly as a protection agent (toxins or antifeedants) against herbivorous insects. \nCould be used for controlled gene expression in scientific research, agriculture and medicine. \nCould be used for the development of selective insect growth regulators for use as environmentally benign insecticides.\n\n\nStorage and Stability:\nShort-term Storage: +4 degrees C\nLong-term Storage: -20 degrees C\nStable for at least 2 years after receipt when stored at -20 degrees C.
