title: [A highly sensitive immunoenzyme analysis using electrochemical detection].
abstract: The authors have developed a method for improving the sensitivity of electrochemical enzyme immunoassay, based on binding the enzymatic reaction volatile component to a complexone, followed by destruction of the complex in a flow-type amperometric detector. The lowest limit of the measured levels of blood serum antibodies and antigens is 10(-11)-10(-12) M. The method was tried in enzyme immunoassay of the blood serum IgE in patients with asthma and chronic obstructive bronchitis. Reduction of IgE level after therapy was found to be a regular feature; the authors claim that it may be considered as one of the criteria indicating the treatment efficacy.
