Four subcellular protein fractions were thus obtained, cytosol, nucleus, membrane/particulate and cytoskeletal fractions.
With some improvement, such as extracting nuclei by water bath heating for dewaxing, we obtained intact nuclei with few foreign materials.
Notably, very similar diffusion coefficients and population distributions were obtained from nuclei of HEK293, HeLa, T98G and TP366 cell lines (Figure 5I and S7).
In G. aurea, the efficiencies were calculated only for the CTAB DNA preparation due to limited plant material and low levels of DNA obtained from nuclei.
The obtained free nuclei in suspension were stained for 30' with 6-diamidino-2-phenylindole (DAPI) solution (10 μM DAPI in 800 mM disodiumhydrogenphosphate) [Sigma D9542, Sigma-Aldrich, St . Louis MO, USA] and evaluated for DNA content by flow cytometry (≥2 × 104 nuclei per histogram).
