title: Glycosidase and phosphatase activities in U-937 and some clones and sublines.
abstract: 1. The activities of nine glycosidases, lysozyme and acid and alkaline phosphatases were compared in the histiocytic lymphoma cell line U-937 and a set of clones and sublines derived from this line. 2. The patterns of the different enzyme activities and selected enzyme ratios have been used as a method to distinguish between different clones and sublines. 3. Sublines with high lysozyme levels were rich in most cell-bound glycosidases. 4. During long-term growth distinct enzyme patterns of individual lines were preserved. 5. The enzyme pattern during a cell culture growth cycle was basically stable.
