Electron microscopy of human plasma lipoprotein separated by ultracentrifugation.
The particle size distribution of the Sf 30 "class" of serum lipoprotein was determined by the electron microscope. Most of the lipoprotein molecules are not spherical but have the shape of ellipsoids of rotation with an axis ratio of 1.5. The molecules of a homogeneous flotation "class" show differences in the reactivity of their lipid moiety demonstrated by their staining properties with osmi...
متن کاملExamination of Lung Parenchyma by Electron Microscopy
In this paper many of the principal structure of the Moral Lung were studied with the help of Electron Microscopy. Detailed description was given of Granular Pneumocytes, Membranous Pneumocytes, Macrophages, and Alveolar Capillaries. A discussion followed on the form and function of Granular Pneumocytes. Acknowledgements I am grateful to the Reza Shah Pahlavi Foundation for its generou...
متن کاملSeparation of the main lipoprotein density classes from human plasma by rate-zonal ultracentrifugation.
The major lipoprotein density classes (chylomicrons-VLDL, LDL, HDL(2) and HDL(3)) were isolated from human plasma in a two-step ultracentrifugal procedure using the Ti-14 zonal rotor. The isolation of the two major high density lipoprotein subclasses (HDL(2) and HDL(3)) was achieved in a 24-hr run using a nonlinear NaBr gradient in the density range of 1.00-1.40. The lipoproteins with a density...
متن کاملHuman rotavirus detection by counterimmunoelectrophoresis versus enzyme immunoassay and electron microscopy after direct ultracentrifugation.
The sensitivity of the counterimmunoelectrophoresis test with NCDV, Wa, and SA-11 rotavirus antisera was 60, 60, and 67%, respectively. The counterimmunoelectrophoresis specificity was greater than 99%, but the low sensitivity is a limiting feature of this test as a first-line immunodiagnostic test for rotavirus detection.
متن کاملFurther resolution of the low density lipoprotein spectrum in normal human plasma: physicochemical characteristics of discrete subspecies separated by density gradient ultracentrifugation.
The molecular basis of the heterogeneity of plasma low density lipoproteins (LDL, d 1.024-1.050 g/ml) was evaluated in 40 normolipidemic male subjects following fractionation by isopycnic density gradient ultracentrifugation into eight major subspecies. The mass profile of our subjects' LDL uniformly displayed single symmetric or asymmetric peaks as a function of density; the peak occurred most...
