Norgen’s FFPE RNA/DNA Purification Plus Kit Dx provides a rapid method for the sequential isolation and purification of total RNA (including microRNA) and genomic DNA from formalin-fixed paraffin-embedded (FFPE) tissue samples for subsequent in vitro diagnostic use. Using formalin to fix tissues leads to crosslinking of the nucleic acids and proteins, and the process of embedding the tissue samples can also lead to fragmentation of the nucleic acids over time. Norgen’s FFPE RNA/DNA Purification Plus Kit Dx provides conditions that allow for the partial reversing of the formalin modifications, resulting in a high quality and yield of nucleic acids. The kit is able to purify all sizes of RNA, from large mRNA and ribosomal RNA down to microRNA (miRNA) and small interfering RNA (siRNA), depending on the age of the FFPE tissue as the degree of fragmentation of the RNA will increase over time.

This kit is designed to be used with any downstream application employing enzymatic amplification or other enzymatic modifications of nucleic acids followed by signal detection or amplification. Any diagnostic results generated using the RNA and DNA isolated with Norgen’s FFPE RNA/DNA Purification Plus Kit Dx in conjunction with an in vitro diagnostic assay should be interpreted with regard to other clinical or laboratory findings.

To minimize irregularities in diagnostic results, suitable controls for downstream applications should be used.

Norgen’s FFPE RNA/DNA Purification Plus Kit Dx is intended for use by professional users such as technicians, physicians and biologists experienced and trained in molecular biological techniques.

Norgen’s FFPE RNA/DNA Purification Plus Kit Dx does not provide a diagnostic result. It is the sole responsibility of the user to use and validate the kit in conjunction with a downstream in vitro diagnostic assay.
