At low probe concentration (10 μM), the former lysine residues possess high reactivity and are completely labeled and the latter are partially labeled because of the limited amount of labeling reagent present; however, at high probe concentration (100 μM), both types of lysines are labeled to almost completion.
After completion of the labeling protocol, replicates of both unlabeled and labeled samples are processed with the user's choice of metabolite extraction and untargeted LC/MS profiling methods.
That's how long it will take Americans to earn enough income to pay off their total 2011 tax obligation to the U.S. government, according to the Tax Foundation, the fiscally conservative think tank that will celebrate April 12 as the day of completion, labeling it Tax Freedom Day.
Many of the study requirements imposed by the FDA and the EMA have made the completion of pivotal labeling studies in children and adolescents with type 2 diabetes nearly impossible.
The In-oxine-labelled WBC should be visually inspected and reinjected into the patient as soon as possible, but not later than 1 h after completion of the labelling procedure.
These studies resulted in the kit formulation rendering the sterile and ready-to-use 99mTc-HYNIC-IL-2 tricine-NA -rhIL-2 stable within 1 h after completion of the labelling procedure.
When the tumours had a diameter of 2 5 mm, the mice were injected intravenously via the tail vein with 3 MBq HPLC-purified [Lys(Ga-DOTA)]exendin-3 (specific activity 110 GBq at completion of the labelling, 50 GBq/µmol at time of injection) corresponding with an exendin dose of 0.3 µg.
After completion of reaction Alexa488 labeled anti-BrdUTP antibody was added and incubated for 2 h.
Importantly, the completion of reverse DIGE labeling controls is not usually necessary, since selective labeling artifacts were shown not to play a significant role in the analysis of soluble proteins [ 166], which considerably lowers the overall time and costs involved in large-scale 2D-DIGE studies.
All cell lines were passaged less than 10 times between thawing and the completion of [U-C] glucose labeling.
