The iCS-digital TM PSC 20q-only kit is based on the digital PCR (dPCR) technology and allows the reliable quantification of the sub-karyotypic 20q11.21 amplification. Gain of 20q11.21 copy-number variant (CNV) is detected in more than 20% of worldwide cultured human Pluripotent Stem Cells (hPSCs) 1-3 and represents 22.9% of the recurrent structural variants identified in hPSCs 4, making it the most common genomic abnormality in hPSCs.
Cells harbouring the 20q11.21 amplification display a selective advantage and can completely overtake the culture in few passages 5.
Detection of the 20q11.21 amplification using a dedicated technology is critical because most of these mutations fall below the size detection limit of conventional G-banding karyotyping (as illustrated on the right, panel B).
The kit also includes a validated normal genomic DNA control sample.
