Abstract
Description
[0001] 1. Field of the Invention
[0002] The present invention relates to equipment and methods for assaying the amount of optical fluorescence, and the degree of fluorescence polarization, in samples.
[0003] 2. Background and Description of the Related Art
[0004] Fluorescence Methods and Terminology.
[0005] Fluorescence involves exciting a molecular group with light of a first wavelength, causing it subsequently to emit light of a second, longer wavelength. The molecular group is termed a fluorophore, and the first and second types of light are termed "excitation" and "emission" light, respectively. Between excitation and emission, the molecular group is said to be in an excited state. Depending on the molecular group involved, the time spent in the excited state can vary widely, from a few nanoseconds to several microseconds. The duration of the excited state is termed the fluorescence lifetime. It is common to chemically engineer a fluorescent marker compound by grafting a fluorophore...
