Electrospray Mass Spectrometry for Measurement of Glycohemoglobin [PDF]

Clinical Chemistry, 1997
With the publication of the results of the landmark 9-year Diabetes Control and Complications Trial (DCCT), the importance of Hb A1c/glycohemoglobin testing in diabetes was firmly established. The DCCT showed, at least in patients with insulin-dependent diabetes mellitus, that the risk for development and progression of the chronic complications of ...

Glycoprotein profiling by electrospray mass spectrometry [PDF]

Journal of the American Society for Mass Spectrometry, 2004
This work compares several different methods of site-specific analysis of glycoproteins using electrospray mass spectrometry. The glycoprotein, oLHalpha (ovine luteinizing hormone, alpha-subunit) was chosen as an appropriate example protein for these studies because of its biological relevance and extreme microheterogeneity.

Lipid Peroxidation in Algae Oil: Antagonist Effects of Natural Antioxidants

Molecules, 2022
Tandem mass spectrometry is proposed to check lipid oxidation, a free radical-mediated phenomenon which effects oxidative deterioration in polyunsaturated fatty acids. Antioxidants are used by the food industry to delay the oxidation process.

A rapid screening, “combinatorial-type” survey of the metalloligand chemistry of Pt₂(PPh₃)₄(μ-S)₂ using electrospray mass spectrometry [PDF]

, 2001
Electrospray mass spectrometry is a rapid and powerful technique for a combinatorial-like survey of the chemistry of the metalloligand Pt₂(PPh₃)₄(μ-S)₂, leading to the successful isolation and crystallographic characterisation of the novel protonated ...

Neutral particle Mass Spectrometry with Nanomechanical Systems [PDF]

, 2015
Current approaches to Mass Spectrometry (MS) require ionization of the analytes of interest. For high-mass species, the resulting charge state distribution can be complex and difficult to interpret correctly.
