Ionophoresis in silica jelly

Abstract

Glycine and serine; alanine and meth-ionine; lysine and glycylglycine; glutamic, aspartic, and cysteic acids were separated by ionophoresis in a slab of silica jelly, containing a swamping concn. of electrolyte, by making use of differences in net mobilities at optimum pH. A chart is given, presenting relationship of net mobility, ion mobility and dissociation constant. A wool hydrolysate was separated into basic, neutral, and acidic fractions at neutral pH.
