Although BSA is not recommended as a calibrant
for MALDI-TOF-MS because it is typically not pure and can produce a systematic error, the determination of the number of HDI molecules adducted was calculated by mass difference.
The concentrations of calibrant
and reference material dilutions were optimized for each platform/reagent combination.
Local PT results with the calibrant
plasmas were plotted against their certified INR values obtained by both orthogonal and linear regression analysis for comparison.
The quality of the curve fits was assessed by back-calculating calibrant
concentrations (see online Supplemental Data 6).
CRP concentrations are routinely measured by nephelometric and turbidimetric immunoassays, in which quantification depends on comparison of the results with those obtained with a calibrant
The mass of somatropin monomer was determined by size-exclusion chromatography using CRS1 or the second WHO material as a calibrant
Furthermore, because the commercially available assays currently use synthetic or recombinant calibrant
peptides that are not glycosylated, the glycosylation of proBNP forms in vivo may adversely influence the performance of these assays.
Although these methods allow simultaneous measurement of both 25OHD3 and 25OHD2, method harmonization is limited, and there is no reference preparation or agreed calibrant
Before joining Biologics Consulting Group, he was COO of Calibrant
Because of the orthogonal design, a single external mass calibrant
was used to achieve better than 5 ppm mass accuracy over an entire sample plate (up to 384 samples).
In a study with a high-resolution MALDI orthogonal TOF MS instrument (PerkinElmer), a single external calibrant
was used to achieve a mass accuracy of <10 ppm (<0.
