The Isolation of Nuclei and Oxidative Particles from Viable Wheat Embryos.

Abstract
Viable embryos of wheat were prepared in gram quantities and from such preparations nuclei and mitochondria were isolated. Embryos were sectioned on a freezing microtome and then gently homogenized in 2 [image] sucrose. Fractionation was accomplished by differential centrifugation. Nuclei thus isolated were morphologically intact and free from impurities: the cytochrome oxidase of the mitochondria had the highest specific activity yet recorded for plant particles.
