Descrizione generale
H2180 is isotopically modified compound consisting of two hydrogen atoms covalently bonded to oxygen-18. It is most convenient to store, transport and use Oxygen-18 in the form of water enriched with this isotope.
Applicazioni
O-18 enriched water is used in Positron-Emission Tomography (PET), a nuclear imaging technique that is used to observe metabolic processes in the body as an aid to the diagnosis of disease such as tumors, staging of cancer, metastasis, dementia, etc. H2180 is currently the only potential universal bacterial substrate suitable for stable isotope probing (SIP). It has been used in the quantification of population-specific growth dynamics in benthic bacterial communities in response to changing redox conditions.

The benthos in estuarine environments often experiences periods of regularly occurring hypoxic and anoxic conditions, dramatically impacting biogeochemical cycles. How oxygen depletion affects the growth of specific uncultivated microbial populations within these diverse benthic communities, however, remains poorly understood. Here

Current limitations in culture-based methods have lead to a reliance on culture-independent approaches, based principally on the comparative analysis of primary semantides such as ribosomal gene sequences. DNA can be remarkably stable in some environments, so its presence does not
