Sensitive single cell detection with DBdirect RT-PCR Probe Mix

Profile the transcripts of interest to determine cell differentiation, stemness, marker expression, mutations, and more with no need for pre-amplification and RNA isolation:The DBdirect™ technology in our RT-PCR mixes allows for direct lysis and qRT-PCR in a single well. The streamlined protocol requires no RNA isolation or pre-amplification. In this study we measured transcripts in FACS sorted single cells directly into the PCR mixes. The results demonstrate that DBdirect™ RT-PCR mixes are sensitive enough to allow transcriptional profiling of single cells. Human cells (CCRF-CEM) were FACS sorted directly into 384-well plates containing 10 µl of the RT-PCR mixes, and subjected to 1-step qRT-PCR. Two assays consisting of primers and probes for GAPDH (Glyceraldehyde 3-phosphate dehydrogenase) and TBP (TATA-box-binding protein) were used for the RT-PCR probe mix. GAPDH is a high-abundance transcript with thousands copies per cell, TBP is a low-abundance transcript with tens of copies per cell based on the protein atlas cell line expression data (if we assume 10 million transcripts per cell). Histograms of Ct values for GAPDH and TBP (n = 60 wells per PCR mix) revealed approximately log-normal distributions, indicating reliable detection. Grey bars indicate wells with no Ct values (also attributable to FACS errors). Results show approximately log-normal distributions of the Ct values, suggesting a reliable detection.
