C-phycoerythrin from Prevents Acute Kidney Injury by Attenuating Oxidative and Endoplasmic Reticulum Stress.

C-phycoerythrin (C-PE) is a phycobiliprotein that prevents oxidative stress and cell damage. The aim of this study was to evaluate whether C-PE also counteracts endoplasmic reticulum (ER) stress as a mechanism contributing to its nephroprotective activity. After C-PE was purified from by using size exclusion chromatography, it was characterized by spectrometry and fluorometry.
