    • Antioxidant capacity of phenolic compounds in acidic medium: A pyrogallol red-based ORAC (oxygen radical ... 
      Atala, E.; Aspée, Alexis; Speisky Cosoy, Hernán; Lissi Gervaso, Eduardo A.; López Alarcón, Camilo (2013)
      A novel ORAC (oxygen radical absorbance capacity) assay to assess antioxidant capacity of phenolic compounds in near-gastric conditions (pH 2.0) is presented. AAPH (2,2'-azo-bis(2-amidinopropane)dihydrochloride) was used ...
    • Free radicals derived from γ-radiolysis of water and AAPH thermolysis mediate oxidative crosslinking of ... 
      Zamora, Ricardo A.; Fuentes Lemus, Eduardo; Barrias, Pablo; Herrera Morandé, Alejandra; Mura, Francisco; Guixé, Victoria; Castro Fernández, Víctor; Rojas, Tomás; López Alarcón, Camilo; Aguirre, Paulina; Rivas Aravena, Andrea; Aspée, Alexis (Elsevier, 2020)
      The enhanced green fluorescent protein (eGFP) is one of the most employed variants of fluorescent proteins. Nonetheless little is known about the oxidative modifications that this protein can undergo in the cellular ...
    • Use of Pyrogallol Red and Pyranine as Probes to Evaluate Antioxidant Capacities towards Hypochlorite 
      Pérez Cruz, Fernanda; Cortés, Constanza J.; Atala, Elías; Bohle, Pamela; Valenzuela, Francisco; Olea Azar, Claudio; Speisky Cosoy, Hernán; Aspée, Alexis; Lissi Gervaso, Eduardo A.; López Alarcón, Camilo; Bridi, Raquel (2013)
      Hypochlorite is a strong oxidant able to induce deleterious effects in biological systems. The goal of this work was to investigate the use of PGR and PYR as probes in assays aimed at evaluating antioxidant activities ...
