Sentence examples for by an internal reference from inspiring English sources

The BMD and BMC results were calibrated by the DXA manufacturer and maintained by an internal reference system that periodically measures bone and soft tissue equivalent reference standards during the patient measurement.

Multiplexing allows for more methylation targets to be analyzed using a single aliquot of sample material with potential for reducing target-to-target differences and monitoring sample adequacy for PCR purpose by an internal reference gene, thereby saving material, time and costs and improving quality control.

As has been proposed early by von Helmholtz [2], this spatial stability may be maintained by subtracting an internal reference signal from the retinal motion signal.

The coordinates of spiddos are established to be reproducibly obtained by an internal reference-mediated normalization (i.e., the coordinates of the two reference points contained in each GP profile (ref 1 and ref 2, Figure  2C) are used to calibrate the coordinates of the featuring points for same DNAs) which is sequence- and size-dependent.

We decided to determine the expression of WNT7A by normalizing to an internal reference gene; thus, the ΔCP was calculated, which represents a more absolute value.

ΔCT was the difference in threshold cycles between the miR and S18 amplicons, and CT was a parameter given by ABI PRISM 7700 Sequence Detector software by negative correlation with an internal reference dye (ROX).

ΔCT is the difference in threshold cycles between the specific RNA and β-actin amplicons, and CT is a parameter given by StepOne Plus Real-Time PCR software by negative correlation with an internal reference dye (ROX).

To better monitor the overall performance and sensitivity of the imaging box, a small piece of paper with multiple coats from a purple marker was placed by the animal as an internal reference [the orange square at the right of the "NIR fluorescence" image in Fig. 3(a) ].

One observed that when a distortion of this kind is introduced repeatedly with different amplitudes, the subjects' visuomotor performance is initially disrupted but gradually normalizes over the course of a prolonged exposure [20] [26]: these outcomes fit well with the view that adaptation is achieved by a gradual modification of an internal reference frame [27] [28].

Mixtures of primers and probes were used for each gene, for SOX1 m and PAX1 m, and for the gene for type II collagen (COL2A) as an internal reference by amplifying non-CpG sequences (iStat, New Taipei City, Taiwan).

Monolayer heights were measured relative to an internal reference provided by TOEG6 patches generated within the DNA monolayer by nanografting.
