The end of the tipless cantilever was positioned precisely on the sTNP at the vertex of the Si3N4 tip by aligning the JPK AFM scanner under an inverted optical microscope (IX 71, Olympus; Figure 3b).
Because one lens is the exact inversion of the other, when they are positioned precisely behind each other the strength of the lens is zero.
With a help of a robotic micromanipulator (MP-225, Sutter, Novato, CA), these electrodes were positioned precisely at 50 µm above the coverslip surface so that the selected cells were in the middle of the gap between their tips.
Unlike standard embolization coils, the AVP can be positioned precisely, its position can be checked with contrast injections before actual detachment, and it can be repositioned if required.
In the monkey, authors have described areas that are cytoarchitectonically comparable to LEC and MEC in rodents, though authors tend to disagree a bit where they should be positioned precisely.
A crucial issue is how stable the SSEP signals are in a given monkey across recording sessions from different days since the EEG cap might not be positioned precisely in the same way between recording sessions.
To do this the nozzles of the LHD were positioned precisely 1.5 mm above the level of the lysate and the alkaline solution was dispensed at the very low rate of 10 μl/s.
The so-called Swedish mutation (K670N; M671L) [ 8] and A673V [ 9] mutations in APP are particularly compelling, because they are positioned precisely at and only 2 amino acids C-terminal to the β-secretase cleavage site, respectively.
A first 3D map of negatively stained supercomplex B from bovine heart, composed of complex I, dimeric complex III and complex IV, provided initial insights into the arrangement of the three complexes in the assembly (Schäfer et al, 2007), but at the limited map resolution of 36 Å they could not be positioned precisely.
