Metal ions bound to the human milk immunoglobulin A: Metalloproteomic approach
(Elsevier B.V., 2015-01-01)
The presence of calcium, iron, and zinc bound to human milk secretory IgA (sIgA) was investigated. The sIgA components were first separated by two-dimensional polyacrylamide gel electrophoresis and then identified by ...
Exploratory analysis using MRM profiling mass spectrometry of a candidate metabolomics sample for testing system suitability
(2021-10-01)
Multiple reaction monitoring (MRM) profiling is an exploratory mass spectrometry (MS) method applicable to the initial screening of complex samples for small molecules based on their chemical functionalities. We report on ...
