일반 설명

Water-18O is an isotopic analogue of water.

애플리케이션

Water-18O is an isotopically modified water, which is appropriate for PET applications.
It can also be used:
  • In paleoclimatology, hydrology, and plant ecology to determine soil stable oxygen isotope analysis of plant cellulose using δ18O.
  • To determine the diffusion of moisture into crystals using secondary ion mass spectrometry (SIMS).

Identifying the targetome of a microRNA is key for understanding its functions. Cross-linking and immunoprecipitation (CLIP) methods capture native miRNA-mRNA interactions in cells. Some of these methods yield small amounts of chimeric miRNA-mRNA sequences via ligation of 5'-phosphorylated RNAs produced
