title: Microconductimetric assay of butyrylcholinesterase activity.
abstract: A conductimetric method for the assay of butyrylcholinesterase is described. A new conductimetric cell has been used which allows increased sensitivity. The physicochemical parameters (pH, buffer concentration) have been optimized. With 1 mM butyrylcholine, butyrylcholinesterase activities down to 2 x 10(-4) U ml-1 may be measured. Serum volumes needed for this assay are in the microliter range (1-5 microliters).
