Consistency - It’s in our RNA
- Fast- easy sample to answer
- Consistent – less handling means less loss, less contamination and less variation
- Robust – kits are validated for accuracy, reproducibility and sensitivity

"The TaqMan Gene Expression Cells-to-Ct Kit has performed consistently. The performance is increased as compared to RNA purification, RT steps and then qRT-PCR. There is less handling, less chance at mistakes. Because of this time savings and increase in sensitivity, I've incorporated this protocol into the Human Embryonic Stem Cell Training Course at the Stem Cell Research Center at Rutgers University (http://www.stemcellcourse.org)."

Simple, Complete Workflows for Gene Expression Analysis without RNA Purification
Cells-to-CT™ Kits allow you to directly get real-time RT-PCR results from cells, without having to purify RNA. These kits provide unsurpassed performance in gene expression and microRNA analysis, including detection of siRNA-induced mRNA knockdown. Cells are simply lysed at room temperature in ≤10 minutes; an optional DNase digestion can be performed concurrently during lysis.
Additionally, the performance of the TaqMan Gene Expression Cells-to-CT Kit was compared to lysate kits from alternative vendors and to purified RNA. Inputs of 100 - 100,000 cells/lysis reaction were examined. The sensitivity of the TaqMan Cells-to-CT Kit protocol was equivalent to that obtained with purified RNA, and it surpassed those from alternative vendors (Figure 1).
|Figure 1: The Sensitivity of the TaqMan® Gene Expression: HeLa cells (100–100,000) were prepared using either traditional RNA purification, the TaqMan® Gene Expression Cells-to-CT™ Kit protocol, or other lysate methods from alternative vendors Q and S. Reverse transcription reactions comprised the maximum recommended sample input for each kit, and real-time PCR was performed in triplicate using a PPIA TaqMan G 15 ene Expression Assay.|
|Figure 2: Detection of limited target sequences. Increasing amounts of NIH3T3 cells (mouse) were added to a constant 10,000 HeLa cells (human). These cells were processed in triplicate by the TaqMan® Gene Expression Cells-to-CT™ Kit or purified reagents provided using a RNA spin column method. All samples were reverse transcribed by the RT for mouse specific (mM B2M) and human-specific (Hs. TKT) genes on all samples in triplicate reactions on a 7900HT Fast Real-Time PCR System.|
