Purifying RNA from cultured cells has traditionally been a highly repetitive, time- and labor-intensive procedure, often involving the use of toxic organic chemicals. The products developed by our RNA experts allow you to isolate RNA of maximum yield, purity, and integrity using several technology formats (organic extraction, glass-fiber columns, magnetic beads, and combinations of these).

You can also analyze cultured cell lysates without first isolating the RNA. In significantly less time, you’ll get qPCR results equivalent to - or in some cases better than - those from purified RNA. The Invitrogen products such as  Cells-to-CT and Single Cell-to-CT product lines offer tremendous performance and handling advantages.

Why is RNA Isolation From FFPE such a Challenge?

The recovery of quality RNA from FFPE specimens can be quite challenging. The fixation process causes cross-linkage between nucleic acids and proteins, and covalently modifies RNA by the addition of monomethyl groups to the bases. As a result, the molecules are rigid and susceptible to mechanical shearing, and the cross-links may compromise the use of RNA as a substrate for reverse transcription. Therefore, in order to utilize FFPE tissues as a source for gene expression analysis, a reliable method is required for extraction of RNA from the cross-linked matrix.

How can you Increase your Chances of Success With FFPE?

There are a number of factors that can impact the overall quality and yield of RNA isolated from FFPE tissues. Here are recommendations to address several key factors:

  1. Upstream tissue procurement and tissue specimen preparation—if possible, tissues should be fixed within one hour of surgical resection. Extensive degradation of RNA can occur before completion of the fixation process. The optimal fixation time is 12–24 hours, using neutral-buffered formalin or paraformaldehyde. Fixed tissues should be thoroughly dehydrated prior to the embedding process.
  2. Block storage—storage of blocks without cut faces, when possible, prevents ongoing damage from exposure to atmospheric oxygen, water, and other environmental factors such as light and infestation (fungus, insects, etc.).
  3. Tissue type, size, and amount being used for RNA isolation—the recommended tissue thickness is 10–20 µm The number of sections used is determined by the tissue type (which impacts cell density) and surface area (recommended size: 50–300 mm2). Excess starting material can cause filter clogging, resulting in poor yield.
  4. Excessive amount of paraffin used for embedding tissues—when possible, excess paraffin should be trimmed away prior to starting the purification protocol. For xylene-based purification methods, two xylene treatments at room temperature should be sufficient for complete deparaffinization. If desired, a more rigorous 37–55°C treatment can be performed for up to 30 minutes. After the xylene deparaffinization, it is crucial that the 100% ethanol is completely removed and the pellets are dry after the two 100% ethanol washes. The magnetic bead method employs novel chemistries to deal with the paraffin that limits input to 20 µm sections.

The MagMAX FFPE Nucleic Acid (NA) isolation kits are designed for rapid, efficient, and automatable isolation of total RNA and DNA from FFPE samples using Invitrogen MagMAX magnetic particles. Invitrogen MagMAX FFPE NA kits offer faster workflows and use less toxic reagents, without sacrificing quality in the process. These kits help deliver nucleic acid yield and purity comparable to the best-in-class RecoverAll filter-based system. The MagMAX FFPE NA kits outperform products with similar protocols, and achieve RNA and DNA yields that are comparable with longer, more hazardous, and lower-throughput protocols.

The RecoverAll Total Nucleic Acid Isolation Kit procedure requires about 45 minutes of hands-on time and can easily be completed in less than 1 day when isolating RNA. FFPE samples are deparaffinized using a series of xylene and ethanol washes. Next, they are subjected to a rigorous protease digestion with an incubation time tailored for recovery of either RNA or DNA. The nucleic acids are purified using a rapid glass-filter methodology that includes an on-filter nuclease treatment, and are eluted into either water or the low-salt buffer provided.
