The sieve test required oven-dried sand samples; however, when the sand sample is mixed with cement paste as a mortar, the oven-dried sand sample absorbs the mixing water.
The investigators found a good overall correlation coefficient of 0.81 between fresh-frozen and FFPE samples; however, when they compared individual sample pairs, they found a low correlation of 0.33, with variability of 0.005-0.81.
This release criterion could be met in all samples tested, however, when gamma-irradiation of the cells was supplemented with UV-irradiation.
The internal information of the sample, however, is lost when thickness of the sample exceeds the 0.1 μm order of magnitude.
However, when sampling or attempting to sample the white filaments from the prints, microsamples of the underbound black matte paint were also dislodged and became available for invasive analysis by transmission FTIR spectroscopy.
The viral loads of HDV IgM-positive samples were significantly higher than those of IgM-negative samples (p<0.0001) (Technical Appendix Figure 1); however, when only samples with detectable HDV RNA from the IgM negative and positive groups were analyzed, there was no statistically significant difference in viral titer (p = 0.45; Technical Appendix Figure 2).
However, when sample components of interest are present in very low concentrations, a substantial volume of sample must be processed through the affinity substrate.
However, when sample sizes are very small, the t-test is not reliable due to the poor estimation for variances; many genes will have small p-values only because their estimated variances are too small.
Immunoprecipitation of endogenous PML recovered comparable amounts of PML from both siGFP and siUSP7 treated samples (Figure 4D, left panel), however, when the same samples were probed for HA, the level of PML containing HA-ubiquitin was greatly decreased after USP7 silencing (Figure 4D, right panel).
