Large-scale purification of ribonucleic acid tumor viruses by use of continuous-flow density gradient centrifugation.
This report describes a 200- to 300-fold increase in the quantity of ribonucleic acud tumor virus particles previously isolated at one time by zonal centrifugation.
متن کاملSeparation of Thyroidal Iodoproteins and Purification of Thyroglobulin by Gel Filtration and Density Gradient Centrifugation.
Thyroglobulin, the major protein component of normal thyroid glands, contains more than 80% of the thyroidal iodine and has been considered the only source of thyroid hormones (1). Aqueous thyroid extracts contain, besides thyroglobulin, other proteins in variable amounts. Essentially, four methods have been used for the characterization of the various components in such extracts and for the pu...
متن کاملPurification of large quantities of influenza virus by density gradient centrifugation.
New zonal centrifuges can conveniently process as much as five orders of magnitude (10(5)) greater sample volumes than conventional swinging-bucket rotors. The continuous-sample-flow-with-banding versions may be used in series with ancillary purification procedures. Here we have studied the combined process: absorption and elution of influenza virus with barium sulfate followed by concentration...
متن کاملPurification and characterization of soluble CD21 from human plasma by affinity chromatography and density gradient centrifugation.
Complement receptor II (CD21) is the receptor for C3d fragments on immune complexes. It also serves as a receptor for Epstein-Barr virus (EBV) and on B-lymphocytes CD21 amplifies signalling through the B cell receptor. CD21 is shed from the surface of the cell and is found circulating in plasma. There, soluble CD21 (sCD21) binds to CD23 and complement fragments, thereby modulating the immune re...
متن کاملPurification of Poly-beta-Hydroxybutyrate by Density Gradient Centrifugation in Sodium Bromide.
Fractionation of fully sporulated cultures of Bacillus thuringiensis by density gradient centrifugation in NaBr produced two bands which were identified as poly-beta-hydroxybutyrate. This technique generated high yields of membrane-bound and unbound granules of exceptional purity and degree of polymerization.
