Sentence examples for below the detection sensitivity from inspiring English sources
In many conditions, such as the low coverage of primers, the absence of a tested gene rearrangement in the tumor genome, DNA degradation in the sample, and the number of tumor cells below the detection sensitivity threshold, clonal gene rearrangement may not be detected.
The absence of reflections of ε-Ti2N or any known titanium oxide in the XRD patterns demonstrates that if present those phases are in quantities below the detection sensitivity of our technique.
This is so because large molecules (>12 kDa) often have the monoisotopic peak intensity below the detection sensitivity.
It is also possible that in porcine prostatic epithelium the amount of Cx43 in secretory cells is below the detection sensitivity of immunohistochemical methods used herein.
Its knock-down by RNAi led to a loss of Piwi protein below the detection sensitivity of Western blot analyses [ 16] and to arrest in macronuclear development [ 25].
Interestingly, the proband showed a similar pattern to the AD cases, whereas Aβ peptides were below the detection sensitivity of direct immunoblotting in patient 2, probably reflecting the lower AD burden seen in this case.
Removing the four best-quality hybridizations lowered the detection sensitivity to below that of the female dataset, and yet, males still showed consistently greater differences in expression (Figure 1b, see Discussion).
As a matter of fact, in such cases the detected power was below the detection system sensitivity level because of the generated high scatter fraction.
In agreement with mRNA levels, TGFβ1 concentration was below the detection limits (sensitivity 4.61 pg/ml) in Act A-LC supernatants, whereas Activin A was induced at 1.05 ng/106 cells (n = 5, n = 6) in TGFβ1-LC.
Regular Sanger sequencing did not detect mutations in the 4 samples that were re-classified from KRAS-WT to KRAS-mutant by COLD-PCR, presumably because the mutant allele % was below the limit of detection (sensitivity ~20percentt for standard sequencing).
We measured residual plasma viremia below 50 copies/ml using an ultrasensitive assay with a detection limit of 2.5 copies/ml and characterized coreceptor use by amplifying V3 env with the same detection sensitivity.
