Abstract This relatively simple method for quantitative estimation of lipoprotein X is based on assay of phospholipids in precipitates of lipoprotein X. We first remove other lipoproteins by precipitation with phosphotungstic acid solution. Lipoprotein X is then precipitated from the supernatant fluid with an alkaline solution of magnesium ion, and phospholipid is determined in this precipitate. Results are linearly related to concentration of lipoprotein X. The CV is less than 3%. Results correlated well with those for agar gel electrophoresis.

Williams and Kallman pointed out one of the major artifacts in the electron microscopy of biological thin sections, namely, the failure to form images of membranes which are inclined at large angles within the section. This loss is a significant consideration in the qualitative interpretation of electron micrographs and especially in the quantitative assay of endoplasmic reticulum and mitochondrial cristae membranes. In order to estimate the effective loss of membrane images it would be desirable to use a specimen which provides a considerable length of membrane tilted at a known angle and a simple method of measuring its “visibility”. The spherical nuclear envelopes of rat liver parenchymal cells satisfy these conditions. Figure 1 shows part of a binucleate liver cell in which the nuclear membrane is clearly visible around the larger section but blurred by oblique orientation in the smaller section.
