Findings by ONC S&I LRI PHWG demonstrated that there are significant gaps in development of (a) functional requirements for PH-R and (b) interoperable standards-based specifications that support PH-R electronic data exchange from clinical care to public health and within public health.
The endemic hydrothermal vent organisms live in the mixing zone according to their tolerance to – and requirements for- various factors (temperature, pH, O2 concentration...)...
The objective of this study was to create a thin film optode for fast pH measurements that meets the requirements for imaging pH-responses from cells as well as for a future hybrid design for detection of multiple analytes simultaneously.
These may be due to requirements for temperature, pH, cofactors, scaffold proteins or post-translational modifications.
This technique is highly amendable to commercial scale-up, reduces the packaging and fabrication requirements for ISFET pH detection, and enables massively parallel droplet interrogation for applications, such as monitoring reaction progression in digital PCR.
To better understand the relative contributions of each stage in the process and consequently the structural requirements of pH responsive peptides for optimal nucleic acid transfer, we used biophysical methods to dissect the series of events that occur during endosomal acidification.
By visual observation it appeared that sodium molybdate had a similar and more intense effect on catechol than uranyl nitrate, as color change was observed even at pH 2 in fresh solution (as opposed to the requirement for a pH 6 for the uranyl-catechol solution).
Precise measurements of relative enzymatic activity of this family are complicated by the requirement for optimal pH and nicotinamide adenine dinucleotide cofactors that requires intact cell models.
Although most of the scientific community and industry consider open ponds as more economically convenient for algae cultivation compared to photobioreactors [ 46, 70, 71], it is undeniable that ponds suffer several limitations that make them unsuitable for large-scale production of algae unless the cultivated organisms have very specific requirements (for example, high pH or high salinity).
The requirement for different pH values could be caused by the difference between the intrinsic properties of the PHB depolymerase of A. latus from those of so-far analyzed depolymerases.
