Imaging techniques should differentiate between specific signals, from the biomolecules of interest, and non-specific signals, from the background. We present a probe containing (15)N and (14)N isotopes in approximately equal proportion, for secondary ion mass spectrometry imaging. This probe designed for a precise biomolecule analysis is insensitive to background signals.

Multi-isotope imaging mass spectrometry quantifies stem cell division and metabolism

The ‘immortal strand hypothesis’ is test, which predicts that during asymmetric stem cell division chromosomes containing older template DNA are segregated to the daughter destined to remain a stem cell, thus insuring lifetime genetic stability, and high-resolution quantification of stable isotope labels are provided.

The bioorthogonal chemistries used for labeling proteins are introduced and their utility for protein labeling is commented on before providing a perspective on future directions.

Multi-isotope imaging mass spectrometry (MIMS) reveals slow protein turnover in hair-cell stereocilia

Protein turnover is quantified by feeding animals with a 15N-labelled precursor amino acid and using multi-isotope imaging mass spectrometry to measure appearance of new protein, and surprisingly, in adult frogs and mice and in neonatal mice, in vivo and in vitro, the stereocilia were remarkably stable, incorporating newly synthesized protein at <10% per day.

Cu-catalyzed azide-alkyne cycloaddition.

The basis for the unique properties and rate enhancement for triazole formation under Cu(1) catalysis should be found in the high ∆G of the reaction in combination with the low character of polarity of the dipole of the noncatalyzed thermal reaction, which leads to a considerable activation barrier.

Adding new chemistries to the genetic code.

The development of new orthogonal aminoacyl-tRNA synthetase/tRNA pairs has led to the addition of approximately 70 unnatural amino acids to the genetic codes of Escherichia coli, yeast, and mammalian cells, which provide new opportunities to generate proteins with enhanced or novel properties and probes of protein structure and function.
