Paper Electrophoresis of Polyglutamyl Peptide
Nature, 1953AFTER capsulated B. anthracis had grown in a modified synthetic medium of Brewer et al.1, a mixture of growth products was isolated from the glass-filtered medium which gave a precipitate with copper sulphate. Crude polyglutamyl peptide was obtained from this precipitate2. An attempt was made to separate the components of the original mixture of growth

Fractionation of Trypsin by Paper Electrophoresis
Nature, 1964P work from this laboratoryl-S has demonstrated the heterogeneity of crystalline trypsin by paper and starch column electrophoresis. This article presents an electrophoretic method of greater resolution. Using this technique it was possible to demonstrate in a sample of crystalline trypsin the occurrence of fractions showing different ratios of ...

A Simple Paper Electrophoresis Apparatus
Nature, 1952ELECTROPHORESIS and ionophoresis on paper are being widely used, and a number of different forms of apparatus for carrying out this technique have already been described. The purpose of this communication is to give further details of an apparatus already briefly described1, which has been used for a considerable time with satisfactory results.

Paper Electrophoresis of Trypanosomal Extracts
Nature, 1959ELECTROPHORESIS has been of value in determining the physico-chemical constitution of cell-free extracts of micro-organisms1,2. These studies have been confined mainly to the bacteria and no such investigation of trypanosomal extracts has been made.

Paper Electrophoresis of Polyhydric Alcohols
Nature, 1955THE polyhydric alcohols or polyols are a group of carbohydrates important both biologically and industrially. Apart from laborious column techniques1, there is no satisfactory micro-method available for the resolution of mixtures of hexitols (sugar alcohols) by themselves or, in particular, in the presence of hexoses.

A simple densitometer for paper electrophoresis
Bulletin of Experimental Biology and Medicine, 1963A description is presented on a nonrecording densitometer for photometry of electrophoregrams in passing light. The instrument may be easily made in any biochemical laboratory with the aid of available parts; the parts may be replaced by analogous ones without impairing the quality of the device. A method is presented for tracing the curve of the optic
