Genomic stability:
Karyotyping assays

Robust, fast and cost-effective genomic stability testing for the success of your research work

Stem cell research scientists need reassurance concerning the genomic stability of the cells they are using in their experiments. The validity of their research work relies in part on the implementation of a robust genomic quality control system.

Traditional karyotyping methods alone will not always provide the level of sensitivity required to reliably detect the most common abnormalities found in stem cells.

In addition, they are generally not suited to regular testing at each step that cells are put under stress due to their processing lead times.

With these constraints in mind, Stem Genomics has developed a range of tests to match your specific requirements and put your mind at rest.

Discover our iCS-digital™ range

The iCS-digital™ range: a sensitive detection solution, specifically designed for your cell type

The iCS-digital™ range has been designed to target specific abnormalities relevant to hPSCs & hMSCs, as well as aneuploidy detection. These assays use highly sensitive digital PCR (dPCR) technology, ideal for small size CNV detection that other traditional methods like G-Banding will miss.

The 5 main advantages of the iCS-digital™ PSC range:

  1. Speed: you can get your results within 3 days or even faster if you use our in-house kit.
  2. Robustness: you get a high level of confidence in your results thanks to the high sensitivity of dPCR combined with our specific set of probes.
  3. Cost effectiveness: Cheaper than G-Banding, the iCS-digital™ range enables you to test more regularly during culture, or introduce an entry level genomic screening in your process.
  4. Convenience: you can choose to do it yourself or have us perform the service for you. Regarding the service, you have several easy options to choose from to send your samples: genomic DNA, cell pellets or cells in fresh culture media (or in cell culture supernatant).
  5. Straightforward results: you get easy data analysis and interpretation of results delivered to your inbox when you choose the service, or you can download the results from the iCS- digital™ software with your kit.

iCS-digital™ Aneuploidy

For hPSCs only

The Duo iCS-Karyo assay* will provide you with a combined G-Banding and iCS-digital PSC solution for assessing the genomic integrity of your cells with high precision.

4 main advantages:

  1. High-resolution detection: identify the most recurrent altered regions in hPSCs, including the sub-karyotypic 20q.11.21 abnormality.
  2. Exhaustivity: G-Banding will provide you with an exhaustive structural and numerical variant analysis.
  3. Peace of mind: we provide full processing services from simultaneous metaphase chromosome preparation and DNA extraction to the final report.
  4. Straightforward results: you will get both assay results sent to you at the same time with a fully interpreted report.

* Only available in Europe, coming soon to the USA. Outside Europe, you can combine your traditional G-Banding analysis with our iCS- digital™ PSC solution.

GoLiver Therapeutics uses iCS-digital PSC to complete their genomic integrity QC
GoLiver Therapeutics
| Angélique Fourrier, R&D project manager
Since we started using the iCS-digital™ PSC for routine control, we have gained a massive degree of confidence in the quality of our cells in long-term culture […] Not surprisingly, by removing the genetic instability factor from the equation, we are rewarded with a highly scalable, efficient and very cost-effective GMP differentiation process for PSCs to produce safe live cell therapy products on a multi-billion cell scale.
