A study has been made to determine whether renal plasma membranes contain an HCO3− stimulated, ouabain insensitive Mg ATPase. Purified mitochondrial, microsomal and brush border membrane fractions have been isolated from rabbit kidney. The microsom

In order to have available a specimen holder suited to measure the beam current as is often required in quantitative electron probe X-ray microanalysis, the rod of a low background beryllium specimen holder of a transmission electron microscope was m

K+ efflux provoked by ethidium proceeds partially as an all-or-none effect by which the diffusion barrier for K+ is disrupted and partially from still intact cells, presumably by exchange against ethidium. This is shown by the application of an elect

The backscattered electron signal, generated in individual cells, has been used to measure the dry mass of these cells. Absolute mass values were obtained by comparing the backscattered electron signals of cells to the signals of polystyrene-latex sp

Metallurgical aspects of five commercial PdAg porcelain-bonding alloys have been investigated using X-ray diffraction, light microscopy and X-ray microanalysis. All alloys are mainly single-phase systems, but they appear to be inhomogeneous due to

Elemental mass fraction determinations on thin biological specimens by quantitative electron probe X-ray microanalysis commonly use a total mass estimation based on registration of X-ray continuum. We have tested whether the accurary of such determin

SUMMARY An improved calibration procedure is described for dry mass determination methods, that are based on microdensitometry of transmission electron micrographs. Polystyrene latex spheres, that are supposed to have a homogeneous mass distribution,

High molecular weight (HM-)crystallin was isolated from lens cortex and lens nucleus of the rabbit by column chromatography on agarose. Electron microscope studies revealed the presence of relatively small aggregates in cortical HM-crystallin, obviou

A new practical approach to quantitative X-ray microanalysis of very small volumes of biological fluids, combining wavelength dispersive analysis and the use of thin films as supports is presented. The results from this technique are compared with th
