The present investigations reveal that the non specific esterase from mouse liver nuclei is exclusively located in the perinuclear cistern and that the nuclear chromatin does not contain any esterase as a rule. However, esterase is associated with lipid droplets which are seldomly found within nuclei. Two different esterases are demonstrated with the employed substrates in the nuclear envelope. It is exemplified that the esterase, found in isolated nuclei, can neither be understood as qualitative nor as quantitative equivalent of the esterase demonstrated ultrahistochemically at nuclear membranes.
