technology) and denatured in 1x Laemmli sample buffer (Bio-rad) containing
2-mercaptoethanol (Sigma Aldrich). Proteins were separated on Criterion
Tris-Glycine eXtended gels (Bio-rad), transferred to PVDF membranes using the
Trans-Blot Turbo system (Bio-rad), incubated with primary antibodies targeting
Catalase (Cell Signaling #14097 & Abcam #ab76024), xanthine oxidase
(Abcam #ab109235), Bcl-2 (Cell Signaling #2870), and with secondary antibody
Goat Anti-Rabbit or Goat Anti-Mouse IgG-HRP (Thermo Fischer). Proteins were
visualized using chemiluminescence on an Azure C600 (Azure Biosystems).
Quantification was performed using LI-COR Image Studio Lite software version
5.2. Vinculin (Sigma Aldrich), tubulin or beta actin (Sigma Aldrich) was used to
normalize for protein input.
