Magdalena C Schneider and Gerhard J Schütz describe how significance testing provides an important and valid addendum to the toolbox of quantitative (single molecule) biology. For two selected applications of single molecule microscopy – Nanoclustering in single molecule localization microscopy (SMLM) and single molecule tracking – they introduce how a single overall p-value...
Compared to room temperature experiments, SMLM performed under cryogenic temperature achieves higher photon yields and, hence, higher localization precision. However, to fully exploit the resolution it is crucial to account for the anisotropic emission characteristics of fluorescence dipole emitters with fixed orientation. We show here that astigmatic imaging in combination...
Approximately one-third of randomly produced knockout mouse lines produce homozygous offspring, which fail to survive the perinatal period. The majority of these die around or after embryonic day (E)14.5, presumably from cardiovascular insufficiency. For diagnosing structural abnormalities underlying death and diseases and for researching gene function, the phenotype of these...
