No, we do not recommend using FFPE samples with the Applied Biosystems RNA Quantification Kit. The purpose of the RNA Quantification Kit is to determine if a degraded or low input sample has enough total RNA to run a WT and/or IVT Pico assay. If this kit is used with FFPE samples, the amount of RNA in the sample may be overestimated due to interference from reagents used when formalin-fixing and paraffin embedding the samples.
