Positive multiple reactions monitoring (MRM) mode was chosen for quantification of each analyte and cystamine dihydrochloride (CYA) was used as the internal standard (IS) for the assay.
The multiple reaction monitoring (MRM) mode was chosen for quantification of the metabolites of the probe substrates (Table 1).
The effectiveness of using frequencies and both frequencies and mode shapes as the data for quantification of damage extent are examined.
For quantification of mode of neuronal death neurons isolated were labeled with FITC (Fluorescene Iso thio-cyanate) conjugated Annexin V and Propidium iodide (PI).
For each compound, the two most intense product ions of the precursor ion were monitored in the SRM mode for quantification and identification, respectively.
Mass spectrometry was carried out under positive ion, electrospray ionization mode, using multiple reaction monitoring (MRM) for quantification of specific target ions.
Dust was extracted with 1 1 hexane:DCM, and extracts were analyzed using negative chemical ionization gas chromatography (GC /mass spectrometry (MS) in multiple ion detection mode (see Supplemental Material, "Analytical method for quantification of the PBDEs").
In our preliminary tests, our entry-level mass spectrometer showed an inadequate sensitivity for quantification of serum 25(OH)D2 and 25(OH)D3 using the kit in nonderivatized mode (data not shown).
For quantification of GCs, the ESI-MS/MS was operated in the multiple reaction monitoring (MRM) mode for monitoring transition pair of the individual protonated precursor ions and their common product ion m/z 264.
The N-terminal SMN antibody, followed by a secondary antibody conjugated to Cy3 (GE Healthcare, 1∶4000) was used for quantification of calpain cleavage by fluorometry using unsaturated digital scans performed on a Typhoon Trio+ Variable Mode Imager (GE Healthcare).
For quantification of the mean fluorescence intensity, image fields were selected at random in the transmitted light mode, without exposure to the fluorescence excitation light.
