In contrast, small analytes such as 3-APTES and HRP, whose diffusivities are faster than 10−10 m2/s, show no significant decreases in response time in both experimental and simulation results when employing the flow-through approach.
However, by introducing gas-phase diffusive transport, or alternatively a convective, flow-through approach, the model predicts that electrodes of identical thickness may provide current densities up to 60 mA cm−2 in air and exceeding 100 mA cm−2 in pure O2.
With respect to the overall purification efficiency for the glyco-variant library of HRP C1A using a two-step flow-through approach, we observed vastly different results (Table III).
Thus, the flow-through sensing approach is especially advantageous for providing more reasonable sensor response times when detecting dilute samples.
In order to realize a label-free flow-through sensing approach with PSi, we developed an open-ended, multilayered, optical microcavity structure fabricated by standard silicon processing that is compatible with integration in on-chip sensor arrays [43].
Sulfur isotope fractionation during microbial sulfate reduction in brackish estuarine sediments was studied using an experimental flow-through reactor approach designed to preserve the in situ physical, geochemical and microbial structure of the sediment.
With the flow-through hybridization approach bacterial DNA of the corresponding reference strains was successfully detected at concentrations of 10 fmol.
The principle of the flow-through hybridization approach is based on the methodology of reverse dot blot (RDB) hybridization in that the targeting molecules flow through the immobilized probes within the membrane fibers.
This again highlights the importance of the single N-glycosylation sites and the respective surface N-glycosylation for the physicochemical properties of HRP and the applicability of the flow-through chromatography approach.
Before applying the synthesized probes in the flow-through hybridization approach, they were tested in vitro by hybridization to universal arrays (UA) on glass slides, as described elsewhere [ 11].
As a conclusion of the optimization experiments, the following application of the designed probes to the flow-through hybridization approach was carried out with taq DNA ligase in the ligation reaction and with biotin labeling for hybridization on Biodyne C membranes.
