Paper Abstract

A microscope-based imaging system has been developed that records single photon emissions from luminescent samples. The time and position of each detected photon is recorded so that integration times for image reconstruction can be selected and adjusted during data analysis. The system performs automated acquisition of brightfield and epifluorescence images that are correlated with the photon images. The features of this system will be demonstrated in the context of studying the dynamics of living cells using luminescent markers such as luciferase and aequorin, which can be introduced by microinjection or transfection. The value of using this approach to study the effects of pharmacological agents on gene expression in living cells will be presented.
