ABSTRACT
<p><b>OBJECTIVE</b>To rapidly detect SOX2 gene using primed in situ labeling (PRINS).</p><p><b>METHODS</b>Human peripheral blood samples were cultured using an optimized method. Sequence of the SOX2 gene was amplified in situ with biotin-labeled specific primers and processed with a tyramide signal amplification (TSA) biotin system. Subsequently, fluorescence-stained signal was detected by streptavidin-Texas red. For the control group, MCF-10F cells were transfected with Lentivirus hSox2.</p><p><b>RESULTS</b>By VideoTesT-FISH software analysis, the long arm of chromosome 3 in the experimental group showed a specific red fluorescence signal, whilst the control samples showed no specific signals for SOX2. Transfected MCF-10F cells showed various efficiency of SOX2 gene integration.</p><p><b>CONCLUSION</b>PRINS utilizes a highly sensitive in situ PCR technique combined with fluorescence labeled oligodeoxynucleotides can synthesize probes in situ, thus greatly reducing the cost of probe and time for detection. It can facilitate identification and classification of induced pluripotent stem cells, and has many potential applications in this prospect.</p>
