title: Time-resolved fluorometer for lanthanide chelates--a new generation of nonisotopic immunoassays.
abstract: Pulsed-light time-resolved fluorometry of lanthanide chelates has proved to be very sensitive for use with nonisotopic immunoassays. We describe a manually operated fluorometer with a conventional xenon flashtube. Sensitivity for 1-s determinations is similar to that of radioisotopic methods.
