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 ...

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

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 Hippopotamus Hæmoglobin
Nature, 1959THE study of animal haemoglobin types is developing rapidly and the results obtained in various species have recently been summarized by Huisman, van der Helm, Visser and van Vliet1. However, the electrophoretic mobility of hippopotamus haemoglobin does not seem to have been studied before, possibly because of scarcity of materials.

Detection of Carbohydrase in Paper Electrophoresis
Nature, 1954THE task of testing and localizing enzymes in a protein mixture subjected to paper electrophoresis is a tedious one. This is particularly true in a fractionation study where the number of tests may be numerous. During the course of such an investigation of the various carbohydrases in an Aspergillus niger fermentation, it became necessary to employ a ...

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.

Micro-Electrophoresis on Filter Paper
Nature, 1951DURING the course of a protein fractionation, it was desired to establish the identity and purity of micro-quantities of proteins. The method described by Cremer and Tiselius1 was investigated with the view of adapting it to the determination of the mobilities and the isoelectric point of proteins as criteria of their purity.
