In one study, MS/MS analysis of newborn spot samples of dried blood collected <24 h after birth was compared with fluorometric analysis
of the same samples.
After three hours the cell monolayers were washed and the extent of bacteria adhesion was quantified by fluorometric analysis
3), fluorometric analysis
was carried out on a spectrofluorophotometer (Bio-Rad Laboratories GmbH, Munchen, Germany).
5% of the Qiagen yield when quantified by Ribogreen fluorometric analysis
after DNase treatment (Fig.
However, there is an indication that it can be increased considerably, based on limited data from two women, obtained by a methodology based on paper chromatography and conversion of androgens to estrogens for fluorometric analysis
Oxidative burst and phagocytosis were measured quantitatively by fluorometric analysis
using commercial methods (PHAGOBURST[R] and PHAGOTEST[R]; Orpegen Pharma) in heparinized whole blood (25).
In principle, the sensitivity of fluorometric analysis
could be improved by attaching many fluorescent groups to the labeled reagents.
Thus, with values for both Phe and Phe/Tyr, only one specimen that was originally false positive by fluorometric analysis
remained false positive by MS/M5, whereas the other 90 specimens originally classified as false positives were negative.
