Relative affinity constants by electrospray ionization and Fourier transform ion cyclotron resonance mass spectrometry: calmodulin binding to peptide analogs of myosin light chain kinase [PDF]

, 2003
Synthetic RS20 peptide and a set of its point-mutated peptide analogs have been used to analyze the interactions between calmodulin (CaM) and the CaM-binding sequence of smooth-muscle myosin light chain kinase both in the presence and the absence of Ca2+.

Identification of Monohexosylceramides From by Electrospray Ionization Mass Spectrometry

Natural Product Communications, 2020
To date, the monohexosylceramides present in the eukaryotic alga Euglena gracilis has not been reported. In this study, we extracted and purified a lipid fraction that eluted similarly to other reported monohexosylceramides.

Desorption Electrospray Ionization-Mass Spectrometry of Proteins [PDF]

Analytical Chemistry, 2007
Desorption electrospray ionization-mass spectrometry (DESI-MS) was evaluated for the detection of proteins ranging in molecular mass from 12 to 66 kDa. Proteins were uniformly deposited on a solid surface without pretreatment and analyzed with a DESI source coupled to a quadrupole ion trap mass spectrometer.
