Nuclei were resuspended in 1 ml of 20 mM Hepes pH 7.6, 150 mM NaCl, 2 mM EDTA, 1× protease inhibitor cocktail (Roche, Basel, Switzerland), 0.5 mM PMSF, 1 mM DTT, 0.5 U/ml of RNAseOUT/SUPERase-In (Invitrogen/Ambion), homogenized using a 1 ml dounce homogenizer (three times with loose pestle, two times with tight pestle), and divided into three samples of equal volume.
The mix was incubated at room temperature for 10 min and then divided into two samples, one of which was subsequently UV cross-linked (Stratalinker) for 12 min on ice whereas the other (negative control) was kept on ice in the absence of UV.
The database was divided into two samples: a development sample by random choice of 450 patients, and the remaining patients in the validation dataset.
The samples were randomly divided into two sample plates and screening using the panel of 352 antibodies was performed for both plates.
Labelled MSCs were fixed in 4% paraformaldehyde and divided into four samples containing increasing numbers of cells (0.125 × 106, 0.25 × 106, 0.5 × 106, 1 × 106).
After catapulting the cells of interest, each group of cells (normal ovarian cyst epithelium, normal ovarian surface epithelium, and ovarian carcinoma) was divided into three samples each, for a total of nine cell samples.
8) The 21 doorknobs divided into seven and four samples, respectively An infection control committee consisting of the IC consultant, representatives from the UDS management and staff, the CV and SVA officials and an executive working group with the IC consultant, a nurse responsible for hygiene and a veterinarian was formed to develop and implement routines and to work with the staff.
As one of the plug-flow reactors, biological aerated filter (BAF) reactor was divided into four sampling sectors to understand the characteristics of elemental nitrogen transformation during the reaction process, and then the different characteristics of elemental nitrogen transformation caused by different NH3 N loadings, biological quantities and activities in each section were obtained.
Given the changes in profile with gestational age the sample sets were divided into two groups; samples of 12 to 14 weeks gestation and samples of 15 17 weeks gestation (see Table 1) for comparative analysis of profile changes that were associated with a Down pregnancy.> -wrap-foot> Numbers in bold indicate subtotals at 12-14 and 15-17 weeks gestation.
The sample was divided into two sub-samples of 75%and25%5%.
