On the specificity of cyclodextrin complexes detected by electrospray mass spectrometry.
Alpha-cyclodextrin complexes with linear alpha,omega-dicarboxylic acids were investigated by electrospray mass spectrometry. These hydrophobic complexes are known to have an equilibrium binding constant that increases with the diacid chain length. However, the electrospray mass spectrometry (ES-MS) spectra showed that the relative intensity of the complex did not vary significantly with chain l...
متن کاملElectrospray mass spectrometry of metal carbonyl complexes †
Methods are described for characterising neutral metal carbonyl complexes using electrospray mass spectrometry, by converting them into ions with suitable reagents. Ionisation techniques included addition of OMe generating [M 1 OMe] species, addition of Ag or Na ions giving the appropriate positive ion, abstraction of acidic hydrogen forming [M 2 H] ions, or (in rare cases) oxidation giving rad...
متن کاملStudying noncovalent protein complexes by electrospray ionization mass spectrometry.
Electrospray ionization mass spectrometry has been used to study protein interactions driven by noncovalent forces. The gentleness of the electrospray ionization process allows intact protein complexes to be directly detected by mass spectrometry. Evidence from the growing body of literature suggests that the ESI-MS observations for these weakly bound systems reflect, to some extent, the nature...
متن کاملDetection of Al(III) and Ga(III) complexes with morin by electrospray ionization mass spectrometry.
The Al(III) and Ga(III) complexes formed by morin (M) in aqueous solution were investigated by means of electrospray ionization mass spectrometry (ESI-MS). In the full scan mass spectra, Al:M showed 1:2 and 2:3 stoichiometric ratios. When (S)-N-acetylserine methyl ester (Ser), as a partial mimic of the serine residue in silk, was added to Al:M and Ga:M complexes in aqueous solution, the mass sp...
متن کاملMitochondrial DNA mutation detection by electrospray mass spectrometry.
BACKGROUND Mitochondrial DNA (mtDNA) mutations cause a large spectrum of clinically important neurodegenerative, neuromuscular, cardiovascular, and endocrine disorders. We describe the novel application of electrospray ionization Fourier transform ion cyclotron resonance mass spectrometry (ESI-FTICR MS) to the rapid and accurate identification of pathogenic mtDNA variants. METHODS In a blinde...
