Research Abstract

Free radical adducts was easily detected by electron spin resonance (ESR) using 2-(5,5-Dimethyl-2-oxo-2λ5-[1,3,2]dioxaphosphinan-2-yl)-2-methyl-3,4 -dihydro-2H-pyrrole 1-oxide (CYPMPO). Signal of free radical adducts did not decrease by adding UW solution or ET-Kyoto solution as organ preserve solution. Oxidative stress during islet isolation may affect islet yield. It was very difficult to detect free radical adducts in blood sample of islet isolation model.
