Objective: To review the prevalence and prognostic significance of fibroblast growth factor receptor 1 (FGFR1) amplification and to establish an association between FGFR1 amplification and the clinical characteristics of nonsmall cell lung cancer (NSCLC).
Compared to FGFR gene mutation and translocation, gene amplification of FGFR is most well studied.
4] station where is least amplifications that the excess of the negative residuals occurs.
One of the parameters describing this change is the amplification factor.
Quantification of amplification products obtained from 88 independent 3'-Ribo-SPIA amplifications of 20 ng of Universal Human RNA (Stratagene) yielded mean (SD) Ct values of 15.
A total of 13 Ribo-SPIA amplifications with 20 ng of total RNA input per amplification gave a present call of 53.
In those cases demonstrating MYCC or MYCN amplifications, we reviewed the histologic characteristics to determine whether these tumors were associated with any previously described histologic patterns of anaplasia.
14) Hybridization signals for the MYCC and MYCN probes were counted in more than 100 nuclei, and the number of chromosome 9 centromeric signals was reported for each nucleus; increases in the number of signals greater than 5 were recorded as amplifications.
Such anomalous amplifications that result from mutation at the primer-binding site may be investigated by using another multiplex or singleplex system that features primers with alternative sequences.
Among the 7,220 male samples analyzed, the X chromosome-specific allele at the Amelogenin locus was not amplified in three samples using the AmpFLSTR[R] Profiler Plus[TM] amplification kit.
Designed to simultaneously detect chromosomal amplifications or deletions of multiple genes in various human cancers, the Vysis GenoSensor Microarray System is the industry's first commercially available system that will enable researchers to rapidly identify and discover key genomic correlations in disease occurrence and outcome.
This is a significant problem for laboratories which perform repeated amplifications of the same target," said Emily Winn-Deen, Oncor's Director of Diagnostic Research and Development.
