Method "In Table 1 [researchers] summarized microelectrode experiments performed in intact cell nuclei of various animal species."
Comments "Close inspection of Table 1 shows a large scatter in NE [nuclear envelope] permeability values, expressed in terms of total NE electrical conductance (GNE). This parameter, derived from the input electrical resistance of the cell nucleus (RNE) and calculated from the current-voltage relation for the NE, stands for the passive electrical leak pathway of the envelope...Inspection of Table 1 shows that Gpore can vary from 150 to >1,000 pS. There is no correlation between NPC [nuclear pore complex] density (number of NPCs per area of NE) and Gpore values...The estimated nuclear pore dimensions calculated from the data of the microelectrode papers are summarized in Table 1."
