[Paper chromatographic analysis of plasmalogens].

Analysis of the Mechanism of Gram Differentiation by Use of a Filter-Paper Chromatographic Technique.

Bartholomew, J. W. (University of Southern California, Los Angeles), Thomas Cromwell, and Richard Gan. Analysis of the mechanism of Gram differentiation by use of a filter-paper chromatographic technique. J. Bacteriol. 90:766-777. 1965.-Data are presented which demonstrate that the mechanism of gram-positivity could not be due solely to factors such as a single, specific gram-positive substrate...

Chromatographic studies on lysozyme.

Lysozyme is a basic protein of low molecular weight (1) which may be prepared readily in crystalline form as the isoelectric protein, the chloride, or the carbonate by the methods of Fevold and Alderton (2). According to the electrophoretic analyses and the sedimentation and diffusion data reported by Alderton, Ward, and Fevold (3), the material isolated by adsorption on bentonite appears to be...

Studies on Digitalis VI

T IS undisputed that the administration of digitalis to patients with many forms of congestive heart failure results in an improvement in both the clinical state and in the abnormal circulatory dynamics that are characteristic of heart failure.'-6 The effects of digitalis in subjects without heart failure are less well defined. Although some glycosides augment the contractile force of nonfailin...

Chromatographic Studies on Nucleic Acids

The nucleic acids are such universal constituents of biological systems and their function is probably so important that it is not surprising that much labour has been spent on the study of their composition. Until very recently there have been no methods of analysis which could be considered more than semiquantitative, and it now seems doubtful whether many published analyses are even approxim...
