Abstract:Light exposure during manufacturing, storage, and administration can lead to the photodegradation of therapeutic proteins. This photodegradation can be promoted by pharmaceutical buffers or impurities. Our laboratory has previously demonstrated that citrate-Fe(III) complexes generate the • CO 2 − radical anion when photoirradiated under near UV (λ = 320−400 nm) and visible light (λ = 400−800 nm) [
