Multicenter Study Using Desorption-Electrospray-Ionization-Mass-Spectrometry Imaging for Breast-Cancer Diagnosis [PDF]

, 2018
The histological and molecular subtypes of breast cancer demand distinct therapeutic approaches. Invasive ductal carcinoma (IDC) is subtyped according to estrogen-receptor (ER), progesterone-receptor (PR), and HER2 status, among other markers. Desorption-

Electrospray ionization of copper—glycine solutions [PDF]

Journal of the American Society for Mass Spectrometry, 1996
We have characterized the electrospray ionization (ESI) spectra of mixtures of the 3d transition metal ion Cu(2+) with both a model amino acid (glycine) and a simple peptide system (glycylglycine). We found what appear to be two major classes of ions.

Electrospray Ionization on Solid Substrates

Mass Spectrometry, 2014
Development of electrospray ionization on solid substrates (solid-substrate ESI) avoids the clogging problem encountered in conventional capillary-based ESI, allows more convenient sampling and permits new applications. So far, solid-substrate ESI with various materials, e.g., metals, paper, wood, fibers and biological tissue, has been developed, and ...
