Ultracentrifugation studies of a urinary mucoprotein which reacts with various viruses.
The isolation from normal human urine of a highly viscous, electrophoretically homogeneous mucoprotein has been described previously (l-3). This substance combines with influenza, mumps, and Newcastle disease viruses and is altered enzymatically by them (l-6). This alteration in the mucoprotein results in loss of the capacity to combine with viruses and in reduction of the electrophoretic mobil...
متن کاملPREPARATION OF HIGHLY PURIFIED SOLVENTDETERGENT COA GULATION FACTOR VII AND FACTOR IX CONCENTRATES FROM PROTHROMBIN COMPLEX (PPSB)
In this study, anion-exchange chromatography was used to purify factor VII and factor IX from prothrombin complex (PPSB), which contains coagulation factors II, VII, IX and X. For this purpose, DEAE-Sepharose CL-6B gel , Pharmacia column XK-26 , high flow rate and two stepwise gradients with phosphate citrate buffer were used. The yield of the two lyophylized products, factor VII and factor...
متن کاملThe separation and quantitative determination of the component sugars of mucoproteins.
In recent years increasing attention has been given to a class of carbohydrate-protein complexes, largely because of the biological activity associated with them (gonadotrophin, thyroglobulin, bloodgroup substances, inhibitors of influenza-virus haemagglutination, Castle's intrinsic factor, etc.). In many of these the carbohydrate moiety represents analytically a minor portion only, though, as ...
متن کاملAn Electrophoretic Examination of a Urinary
A number of the properties of a mucoprotein which has been isolated from human urine and obtained in a highly purified state are described in the preceding paper (1). This substance is capable of reacting with certain viruses and several features of the interaction with influenza viruses are those of an enzymesubstrate system. The mucoprotein is altered by active influenza viruses; one evidence...
متن کاملStudies of Two Kinds of Virus Particles Which Comprise Influenza A2 Virus Strains
Two kinds of virus particles have been found in varying proportions in influenza A2 strains isolated during the 1957 pandemic. Pure populations of the different particles were obtained, and these substrains were genetically stable on serial passage in the chick embryo. The two virus particles differ markedly in several biological properties though they are antigenically similar. One kind of par...
