Biophysical Properties of Lumbricus terrestris Erythrocruorin and Its Potential Use as a Red Blood Cell Substitute
Previous generations of hemoglobin (Hb)-based oxygen carriers (HBOCs) have been plagued by key biophysical limitations that result in severe side-effects once transfused in vivo, including protein instability, high heme oxidation rates, and nitric oxide (NO) scavenging. All of these problems emerge after mammalian Hbs are removed from red blood cells (RBCs) and used for HBOC synthesis/formulati...
متن کاملProtein Concentration and Diafiltration by Tangential Flow Filtration
PURPOSE Membrane-based Tangential Flow Filtration (TFF) unit operations are used for clarifying, concentrating, and purifying proteins. This technical brief is a practical introduction to protein processing using tangential flow filtration. It is intended to help scientists and engineers achieve their protein processing objectives by discussing how the choice of key components and operating par...
متن کاملCytodifferentiation during Spermiogenesis in Lumbricus Terrestris
The structural changes during spermiogenesis were studied on developing spermatids in seminal vesicles and receptacles of Lumbricus terrestris fixed in glutaraldehyde-osmium tetroxide and embedded in Epon-Araldite. The centriole plays a prominent role in the morphogenesis and organization of the microtubules of the manchette and flagellum. Microtubules arising from the centriole extend anterior...
متن کاملCeramide glycanase from the earthworm, Lumbricus terrestris.
Ceramide glycanase (CGase) is an enzyme that cleaves the linkage between the sugar chain and the ceramide. To make this enzyme readily available, we have developed a simple method for preparing it from the earthworm, Lumbricus terrestris. The method involves Bio-Gel A-0.5m, octyl-Sepharose and p-aminophenylthiogalactoside-agarose column chromatography. By gel filtration, the molecular mass of e...
متن کاملComparison of Diafiltration and Tangential Flow Filtration for Purification
Purpose. The study reports evaluation of different purification processes for removing surplus surfactant and formulating stable nanoparticle dispersions. Methods. Nanoparticle formulations prepared from poly(D,L-lactide-co-glycolide) and polyvinyl alcohol (PVA) were purified by a diafiltration centrifugal device (DCD), using 300K and 100K molecular weight cut-off (MWCO) membranes and a tangent...
