Aicrosome(微粒体) Microsomes(100-200nm)are heterogeneous mixtures of similar-sized vesicles,formed from membranes of the ER and Golgi complex. Microsomes retain activity during purification, allowing studies of function and composition. Types: rough microsome and smooth microsome. 20 This document is produced by trial version of Print2Flash.Visit www.print2flash.com for more information
