Summary
Several starting materials and procedures for the extraction and purification of granulocyte chalone activities were tested and evaluated. Among others, leukoadhesion of bovine blood granulocytes on nylon and cotton wool and direct extraction with polar organic solvents were found suitable. Following PVP-leukapheresis ascites fluids were collected from rats, purified by ultrafiltration and Sephadex G 25 chromatography to yield 2 inhibitors at Ve/Vo=2.1 and 2.6 and one stimulator at 2.0 by the in vitro3H-thymidine test. Fraction 2.1, which has met the criteria of a granulocyte chalone by the diffusion chamber and agar colony test, was found thermostabile and to contain several peptides. Yet evidence for the peptide nature of the inhibitor is not conclusive. Extracts from bovine blood granulocytes contained only the inhibitor at 2.1. Problems related to the in vitro test for chalone activity were discussed.
Zusammenfassung
Verschiedene Ausgangsmaterialien und Verfahren zur Extraktion und Reinigung von Granulozyten-Chalon-Aktivitäten wurden untersucht und kritisch beurteilt. Darunter erwiesen sich Leukoadhäsion von Rinderblut-Granulozyten an Nylon- und Baumwoll-Watte und direkte Extraktion mit polaren organischen Lösungsmitteln als lohnend. Durch PVP-Leukapherese gewonnene Ascites-Flüssigkeiten von Ratten lieferten nach Ultrafiltration und Sephadex G 25-Chromatographie im In-vitro-Test mit3H-Thymidin 2 Inhibitoren bei Ve/Vo=2,1 und 2,6 und einen Stimulator bei 2,0. Fraktion 2,1, die mit dem Diffusionskammer- und Agarkolonie-Test die Eigenschaften eines Granulozyten-Chalones erfüllt hat, war thermostabil und enthielt verschiedene Peptide. Doch ist die Peptid-Natur des Inhibitors nicht schlüssig bewiesen. Extrakte aus Rinderblut-Granulozyten enthielten nur den Inhibitor 2,1. Auf die Problematik des In-vitro-Tests zum Chalon-Nachweis wurde hingewiesen.
