LITERATURE
diagnostics
-
the enzyme is a marker of chemotherapy dose modification during the induction phase in children with acute lymphoblastic leukemia, overview
medicine
-
the enzyme is widely used in chemotherapy for treatment of children with acute lymphoblastic leukemia, in vivo and in vitro resistance of the cells to the enzyme can occur
synthesis
optimization of production and process conditions for recombinant human enzyme. The maximum biomass yield of 6.7 g/l of enzyme is achieved with fed-batch fermentation. The refolding efficiency is optimal at pH 8.5 (84%) and temperature 25°C (86%)
