In plants, ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO) is an important enzyme in the Calvin cycle, catalyzing the first step of carbon fixation. Because of its critical role in photosynthesis, RuBisCO comprises 30-60% of the total protein content in green leaf tissue and represents a major protein which can interfere with determination of(More)
Proteomic analysis can be hampered by the large concentration distribution of proteins. Immunoaffinity techniques have been applied to selectively remove high abundant proteins (HAP's) from samples prior to analysis. Although immunodepletion of HAP's has been shown to enable greater detection of low abundance proteins, the resulting fractions are often(More)
F(2)-isoprostanes are a unique class of prostaglandin-like compounds formed in vivo, which have been established as biomarkers of oxidative stress. Accurate analysis has been challenging due to lack of specificity for the isoforms of isoprostanes and lengthy sample preparation procedures to enable trace quantitative analysis. A quantitative analytical(More)
