Abstract
Certain phenalenimine fluorescent compounds represented by the structure ##STR1## wherein R' and R' are independently hydrogen, alkyl, cycloalkyl, aryl or a heterocycle, or R' comprises the carbon and heteroatoms which forms a fused ring with the compound nucleus, are useful in biomedical and analytical determinations. These compounds can be used for staining cells, as well as for the determination of various analytes found in human or animal biological fluids. Such determination can be carried out in solution or by using dry analytical elements. The fluorescent compounds can be reacted with quinone nuclei to form reducible compounds which are also useful in analytical methods. In addition, the compounds can be incorporated into what are known as 'loadable' latex particles to form detectable labels and biological reagents.
