Several fluorogenic dyes can be used simultaneously in a sample as long as they each emit light at a different measurable wavelength.

Question

Quizplus · Accepted Answer

This is true. Fluorogenic dyes can be used simultaneously as long as they emit light at different measurable wavelengths, which allows them to be distinguished from each other. This is often used in multiplex assays, where multiple targets can be detected in a single sample by using different fluorogenic dyes.
