Stable isotopic labeling in proteomics [PDF]

open access: yesPROTEOMICS, 2008
AbstractLabeling of proteins and peptides with stable heavy isotopes (deuterium, carbon‐13, nitrogen‐15, and oxygen‐18) is widely used in quantitative proteomics. These are either incorporated metabolically in cells and small organisms, or postmetabolically in proteins and peptides by chemical or enzymatic reactions.

Poly(3-Hydroxybutyrate) Biosynthesis from [U-13C6]D-Glucose by Ralstonia eutropha NCIMB 11599 and Recombinant Escherichia coli

open access: yesMicrobiology Research, 2023
The use of stable isotope-labeled polymers in in situ biodegradation tests provides detailed information on the degradation process. As isotope-labeled raw chemicals are generally expensive, it is desirable to prepare polymer samples with high production

gQuant, an Automated Tool for Quantitative Glycomic Data Analysis

open access: yesFrontiers in Chemistry, 2021
MALDI-MS-based glycan isotope labeling methods have been effectively and widely used for quantitative glycomics. However, interpretation of the data produced by MALDI-MS is inaccurate and tedious because the bioinformatic tools are inadequate.

ISOTOPIC LABELLING OF THE MOUSE BLASTOCYST [PDF]

open access: yesReproduction, 1968
In the implanting blastocyst of the mouse, the first trophoblast cells to penetrate the uterine epithelium contain large basophil inclusions. It has been suggested that these inclusions originate at an earlier stage within cells of the inner mass which move into the trophoblast just after disintegration of the zona pellucida (Wilson, 1963; Potts ...

Synthesis of isotopically labeled epothilones [PDF]

open access: yesJournal of Labelled Compounds and Radiopharmaceuticals, 2013
The epothilones, including epothilones B and D, are macrocyclic lactones, which have potent cytotoxicities and promote the polymerization of tubulin to mictotubules by binding to and stabilizing the tubulin polymer. They have a very similar mechanism of action to paclitaxel (Taxol®).

GPCR structural characterization by NMR spectroscopy in solution

open access: yesActa Biochimica et Biophysica Sinica, 2022
In the human proteome, 826 G-protein-coupled receptors (GPCRs) interact with extracellular stimuli to initiate cascades of intracellular signaling. Determining conformational dynamics and intermolecular interactions are key to understand GPCR function as

Enzymatic incorporation of an isotope-labeled adenine into RNA for the study of conformational dynamics by NMR.

open access: yesPLoS ONE, 2022
Solution NMR spectroscopy is a well-established tool with unique advantages for structural studies of RNA molecules. However, for large RNA sequences, the NMR resonances often overlap severely.

Research Progress in Radioiodine Labeling Methods of Biomolecules

open access: yesJournal of Isotopes, 2023
Radiopharmaceuticals derived from targeted molecules labeled with radioiodine have always been the research hotspots in the field of nuclear medicine. Radioiodine labeling also has a clear application demand in pharmacokinetic research.
