Cells-to-CT™ Bulk Fast Advanced RT Reagents

There is no reason why the Cells-to-CT system shouldn’t work with any cell line. However, due to differences in cell size and composition, the maximum number of cells per lysis reaction may be slightly different for different cell lines. We recommend testing for inhibition and optimal cell input by using the TaqMan Cells-to-CT and SYBR Green Cells-to-CT Control kits.

The reverse transcriptase in this kit can make cDNA up to 7 Kb. However, this was not specifically tested on Cells-to-Ct lysates.

Yes, the Stop Solution provided in the 2-step Cells-to-CT kits contains RNase inhibitor.

The TaqMan Gene Expression Cells-to-CT kit has been validated for duplexing. If you want to set up a multiplex real-time PCR reaction with 3 assays, we recommend using the TaqMan Fast Advanced Cells-to-CT kit (https://www.thermofisher.com/order/catalog/product/A35374).

To prevent signal from genomic DNA in the Cells-to-CT real-time PCR reaction, we recommend using a TaqMan assay or primer set that spans an exon-exon boundary, and adding DNase I to degrade genomic DNA during the lysis reaction. For optimal DNase activity in the lysis reaction, we recommend the following:
1. Ensure all media is removed from the cells.
2. Wash each well or cell pellet with an equal volume of room temperature 1X PBS.
3. Ensure the lysis reaction happens at room temperature. The lysis reaction may not reach room temperature if the plate is on ice prior to adding Lysis Solution, or cold Lysis Solution is added.
4. Warm the Lysis Solution to room temperature before adding to the cells.
5. Perform the lysis reaction at 25 degrees C for up to 8 minutes.
