To improve the characterization of electrophoretic lipoprotein subfractions, we developed two new techniques for analyzing lipoproteins after electrophoresis on thin agarose layers. Overlay with antisera exactly localizes specific apoproteins without any distortion caused by antigen diffusion; electron microscopyof eluted fractions determines the varying particle-size distribution. Applied toge...

Insoluble proteins were investigated in the visual cortex (area 17) and somatic sensory cortex of one month old kittens. Visual deprivation did not affect the electrophoretic pattern but changed percentage distribution of proteins in both cortices. Some of the alterations seemed to appear only in the visual cortex, which is morphologically and functionally deficient in deprived kittens. Electro...

The analytical electrophoretic pattern of the buffer-soluble proteins extracted from bacterial cells is both characteristic and descriptive of the organism (Hess et al., 1957; Wagman et al., 1958; Rodenberg, 1958). Further, a relatively large fraction of the material of the cell can be studied by the electrophoretic method. Hess et al. (1957) using successive extractive procedures on three stra...

A few recent communications deal with electrophoretic observations concerning the effect of heparin on alimentary hyperlipemia. Nikkila (1) found by moving boundary electrophoresis a decrease of beta-1 globulin and an increase in alpha-1 globulin after the injection of heparin. Rosenberg (2) and Fasoli (3) noted on paper electrophoresis an increase in the mobility of the beta lipoproteins which...
