Labelling data is typically a task for end-users and is applied in own scripts or functions rather than in packages. However, sometimes it can be useful for both end-users and package developers to have a flexible way to add variable and value labels to their data. In such...
For the cross validation of the RCY measurements, the ITLC-strip used for TLC-scanner can be cut at the appropriate retention factor, after separation is proven between the labelled and unlabelled radiopharmaceutical (Fig. 6). Thereby the top and the bottom of the strip can separately be measur...
These were identified as (1) the spectrum of unlabelled (endogenous) ascorbic acid, and (2) a linear combination of the spectra of the two labelled species used. The absence of a third factor in the decomposition indicates that there is no difference in the behaviour of the 13 C- and 2...
The structure and mass of unlabelled Z-OMPD and 13C-labelled [1,5 13C2]Z-OMPD were confirmed by 1H-NMR spectroscopy and mass spectrometry (Fig. S2), respectively. pH sensitivity To evaluate the pH sensitivity of the 13C-labelled carboxylic acid carbons, a titration series of thermal 13C...
The static image data were, however, in general agreement with the biodistribution data showing high uptake in the kidney and bladder regions. The main difference between the two radiotracers was a high uptake of radioactivity in the thyroid in the case of [124I]annexin V. In this study, we...
However, the T g values of the labelled PS samples are higher than the unlabelled ones with the difference widening as M n decreases. This difference is explained by a decrease of chain end mobility and hence of free volume caused by bulky end groups....
we injected simultaneously hyperpolarized ZA and urea via a catheter directly into the filled rat bladder. The source of the hyperpolarized signal of both ZA and urea (Fig. 3a,b) clearly stemmed from the bladder. From the localized spectroscopic imaging data (Fig. 3d), a pH map (Fig. 3c)...
The mixture was heated at 95 ◦C up to 10 min and consequently passed through a light C18 cartridge (Waters, Milan, Italy) to eliminate unlabelled gallium-68 and polar by-products. The cartridge was washed with 3 mL of saline and 1 mL of 10% ethanol solution and then eluted with 1 ...
