Detection of Carbonylated Proteins in 2-D SDS Page Separations

Abstract

Protein carbonyls are an index of protein oxidation which, in turn, reflects the interplay of oxidative stress and degradation of oxidatively modified proteins. Protein carbonyls are increased in brain proteins in aging and age-related neurodegenerative disorders, including Alzheimer's disease. In this chapter, we outline methods to detect protein carbonyls following two dimensional-based separation of brain proteins.
