title: Lysosomal enzyme activities in cultured lymphoid cell lines.
abstract: Several lysosomal enzyme activities in cultured lymphoid cell lines were studied during 3 phases of cell culture; logarithmic growth phase, stationary phase and decline phase. Enzyme induction during cell growth was found in N-acetyl-hexosaminidase, beta-galactosidase and alpha-L-fucosidase, but no induction in alpha-D-mannosidase, alpha-glucosidase and beta-glucuronidase. The latter two enzymes were unchanged during all cell culture phases. A drop in alpha-L-fucosidase and alpha-D-mannosidase activity was found during the stationary and decline phases of cell culture.
