As expected, DNA isolated from nuclei consistently yielded nuclear DNA with fewer chloroplast and mitochondrial DNA copies, as compared to the total cellular DNA prepared with the CTAB method.
This assay yields nuclei with functional NPCs while allowing us to control the composition and concentrations of transport factors and cargos.
A total of three replicates were analyzed for each tissue and genotype with the exception of seedlings, where only two replicates were included due to very low yield of nuclei from this tissue type.
The current ChIP experiments show that nuclear extracts from control and HBR-treated EBs generated an amplified product for the SBE binding site on the Nkx-2.5 promoter and that the amount of amplified DNA yielded from nuclei extracted from HBR-treated ES cells was significantly higher than that derived from control cell nuclei.
We monitored progression through meiotic divisions by counting the number of nuclei, where the MI division yields 2 DAPI staining spots and the MII division yields ≥3.
Aberrant nuclei refer to nuclei with abnormal morphology, such as fragmented nuclei or nuclei with irregular shapes.
We report here three protocols that yield high quality DNA from nuclei isolated from several monocot and eudicot plant species.
For instance, in MK2 (Figs 2 and 5), the injections in PMd and PMv yielded fairly abundant retrograde labeling in nuclei located in middle and caudal portions of the thalamus, in particular not only in LP and mediodorsal nucleus (MD) but also in PuM, centre median nucleus (CM -parafascicular nuCM -parafascicularl lateral nucleus (CL), and limitans nucleus (Li).
The in-depth histological examination, supported by the morphometric analysis, of the brainstem in SIUDS/SIDS cases frequently yielded a diagnosis of hypodevelopment of important nuclei and/or neuronal structures checking vital functions.
This similarity network retained 131,162 environmental sequences, and yielded 82 connected components: adding environmental sequences made most of the nuclei grow into independant connected component, but a in a few cases two nuclei were united into the same component.
