The Preparation and Properties of Highly Purified Ascorbic Acid Oxidase
1. A method is described for the preparation of a highly purified ascorbic acid oxidase containing 0.24 per cent copper. 2. Using comparable activity measurements, this oxidase is about one and a half times as active on a dry weight basis as the hitherto most highly purified preparation described by Lovett-Janison and Nelson. The latter contained 0.15 per cent copper. 3. The oxidase activity is...
متن کاملComposition and properties of a highly purified toxohormone preparation.
The amino acid and lipide composition of a highly active toxohormone preparation (TH2) from human malignant tissues was investigated. Approximately 80 per cent of the TH: could be accounted for as polypeptide, with leucine, alanine, glutamic, and aspartic acid being present in the highest concentrations. The remaining ~0 per cent consisted largely of phospholipides. The TH~ fraction was divided...
متن کاملPreparation and certain properties of highly purified streptokinase.
Procedures are described for the preparation of highly purified streptokinase by column chromatography on diethylaminoethyl cellulose and by column electrophoresis in a sucrose density gradient. Preparations chromatographed at least twice on diethylaminoethyl cellulose are shown to be essentially monodisperse on the basis of ultracentrifugal and gel electrophoretic analyses and constancy of spe...
متن کاملHighly purified synaptosomal membranes from rat brain. Preparation and characterization.
Synaptosomal plasma membranes were isolated from whole rat brain by a method derived from several existing ones. The procedure involves the sequential centrifugation of a crude mitochondrial fraction through a discontinuous sucrose gradient and a continuous cesium chloride gradient. The material is then subjected to osmotic lysis and centrifuged through an additional discontinuous sucrose gradi...
متن کاملThe Preparation of Partially Purified
The treatment of tuberculous meningitis is frequently hindered by the formation of exudate within the cerebrospinal spaces. This exudate may obstruct the cerebrospinal circulation and give rise to the complications of subtentorial, basal cistern, and spinal block. Furthermore, the presence of exudate predisposes to the occurrence of tuberculous arteritis, which is responsible for the cerebral a...
