SLB, respectively, compared to EVs from T cells of the same donors with a median diameter of 65 ± 25 nm. More detailed analyses using silica bead standards for size segmentation revealed a higher frequency of events larger than 113 and 155 nm in tSV compared with EVs (...
in electrical contact therewith. The probe is adjustably movable into and out of the waveguide so that the probe together with the bushing thereabout forms a quarter wavelength stub extending into the waveguide and resonant at the frequency of the input signal. Electrical energization of this probe...
