Über die elektrophoretische Differenzierung und Klassifizierung von Proteinen - VI. Disk-Elektrophorese und isoelektrische Fokussierung in Polyacrylamid-Gelen von Proteinen und Enzymen aus Tomaon, Gurken, Zuckermais und Zwiebeln

Acetone-dry powders which are excellently suited for the enrichment of proteins and partially also for enzymes, have been extracted with buffers. Separation was accomplished using disc-electrophoresis and isoelectrical focussing. The protein distribution patterns of fleshy tomatoe varieties largly correspond to each other. In the protein distribution patterns of cucumbers, sugar-maize and onions, the protein pherograms indicate sort-dependency. The zymograms partially differ very much. This can not entirely be attributed to differences of the sorts.
