Sample substitution can be an acceptable data-collection strategy: the case of the Belgian Health Interview Survey.
2707 households (RR hh: 55.5%) participated. For the three successive (matched) substitutes, the RR dropped to 45%. The composition of the net sample resembles the one of the initial samples. Applying ...
An application of mass spectrometry for quality control of biologicals: Highly sensitive profiling of plasma residuals in human plasma-derived immunoglobulin.
concerns and hence there is a need for highly sensitive profiling of residual plasma source proteins. This study aims to consider LC- ESI- QTOF data-dependent acquisition in combination with sample ...
Proof-of-concept study of a new LC-ESI-MS/MS-based assay to identify Aspergillus spp. in artificially mixed samples using species/genus-specific proteotypic peptides
the pure material. In conclusion, we have developed an innovative LC- ESI- MS / MS assay which has the capacity to determine the composition of mixed samples, and its proof of concept is shown here ...
