Abstract

Compositions, devices, systems and methods for reducing and/or preventing photodamage of one or more reactants in illuminated analytical reactions by one or more of incorporating photodamage mitigating agents within the reaction mixture and/or interrogating different observation regions of the reaction mixture for a period that is less than a photodamage threshold period.
