Abstract
A method for labeling concentration density differentials of an analyte in a biological sample is provided. The method may including the steps of: binding an enzyme to an analyte contained in a sample, the enzyme capable of acting on at least two chromogens; incubating the sample with a first chromogen for a first time period to generate a first color chromogen-enzyme product, the first color chromogen-enzyme product reflecting light observable as a first color; and incubating the sample with a second chromogen for a second time period to generate a second color chromogen-enzyme product, the second color chromogen-enzyme product reflecting light observable as second color. A combination of the light observable as the first color and the light observable as the second color may be observable as a third color, and each color may describe a different analyte density in the biological sample.
