25 x 2 rxn

Real-time PCR

IMG-116 qPCR

7500 FAST Real-Time PCR System (ThermoFisher)

  • Quantitative assay: it allows determining the percentage of molecular chimerism in the post-transplantation period by real-time PCR (qPCR) relative quantification of the informative marker with respect to the total amount of DNA present in the sample.
  • Detection limit: 0.01%
  • Limit of quantification: 0.1%
  • It contains a positive control that will act as a calibrator and will allow the relative quantification of the markers, without the need to use the pre-transplant recipient sample.
  • It complies with the quality requirements specified by ISO 13485 and ISO 14001 in relation to the materials used in its manufacturing process.
  • For use in research.

Real-time PCR uses a system of sequence-specific oligonucleotides and hydrolysis probes to specifically amplify targets of interest.  The quantitative analysis of chimerism implements a relative calculation system implemented by the method established by Pfafl that takes into account the efficiency of the amplification system and the “cycle threshold” (Ct) values ​​obtained for an endogenous control or calibrator, included in the kit as a positive control. From these values, the system allows the calculation of chimerism in each trial. Likewise, Imegen has developed a calculation tool to facilitate the analysis of chimerism by real-time PCR (
