Wilson and I took turns monitoring the traps for over 10 hours.
Constant force experiments were performed with a PID controller loop that monitored the trapped bead positions and controlled the trap separation to maintain a constant tension on a tethered DNA molecule.
In our own laboratory, we make use of a variant of this approach, applying a charge-pickup electrode in an electrostatic fast-ion beam trap to monitor the ion density oscillating in the trap and carry out Fourier-transform (FT) mass spectrometry on ensembles of molecular ions [26, 27].
This technology monitors the interface trap density (D it) spectra, D it vs. V SB position in the Si energy gap, and the total charge density by means of the multi-metrology Semilab PV-2000 platform (Semilab Co. Ltd., Shanghai, China) [15].
We have used cytotoxicity assay, reporter SEAP assay to monitor the hTERT expression, and TRAP-G4 assay to measure the relative activity of these compounds, and have examined how the attached substituents affect their ability to influence telomerase.
To monitor: The status of twenty-nine men trapped after an explosion at the Pike River Coal Co. mine in New Zealand.
As the up-regulation of three SHR genes upon stress in S0 corresponded well with an increased number of SHR events monitored by the trap constructs, the correlation also holds true for non-stressed S1 and S2 populations originating from the stressed S0 plants.
We overcame this difficulty by developing an optical trapping technique to monitor the rotation of the flagellar motor [3].
A non-invasive optical detection system including a magnetic trap is developed to monitor the extracorporeal venous bloodstream for the presence of released microparticles.
