FFPE Resources

Brain FFPE tissue creates unique nuclei isolation challenges. Myelin debris, lipid contamination, and fragile neuronal nuclei require controlled automated processing to preserve cell-type diversity for single-nucleus sequencing.

Practical guide to postmortem brain FFPE challenges: necropsy timing, fixation variability, biobank sourcing, myelin debris, and how the Singulator 200+ standardizes nuclei extraction.

Standardize brain FFPE nuclei extraction across consortium sites with the Singulator 200+. Eliminate operator variability, prevent batch effects, and scale for atlas projects.

Ronan Chaugnet from Memorial Sloan Kettering shares several years of head-to-head benchmarking data comparing nuclei extraction platforms for FFPE tissue. The Singulator 200+ and Miltenyi GentleMACS both outperformed manual approaches across glioblastoma, liver, lung, pancreas, and tumor samples, with the Singulator 200+ standing out for its fully automated, enzyme-free workflow. Ronan also walks through three methods his lab has built on top of automated FFPE extraction: 10X Genomics FLEX for high-quality gene expression, PERFF-Seq for sorting rare cell populations by RNA markers, and GIFT-Seq for detecting 600+ mutations at single-cell resolution from archival tissue.

This protocol describes how to isolate, count, and prepare single nuclei from FFPE (formalin-fixed, paraffin-embedded) tissues for single-nuclei sequencing assays using the Singulator 200+ platform. Deparaffinization and rehydration of the tissue using solvent and various concentrations of ethanol are conducted on the Singulator 200+ platform along with automated nuclei isolation.

Brain atlases are being built. Archival tissue is finally talking. How standardized nuclei extraction and platform-agnostic analysis are solving neuroscience's oldest cold cases.

Manual extraction of nuclei from FFPE brain tissue destroys 50 to 60 percent of starting material. Fragile neurons die first, leaving biased results. Here is what goes wrong.

Millions of FFPE brain tissue blocks sit in biobanks worldwide, holding decades of evidence about Alzheimer's, Parkinson's, and neurodegenerative diseases. What if we could reopen these cases?

Manual FFPE processing destroys fragile neuronal nuclei and produces variable results. The Singulator 200+ automates the workflow with a two-cartridge system that delivers consistent, operator-independent results from irreplaceable brain tissue.

NIH biobanks give you one allocation of irreplaceable brain tissue. Manual processing destroys 50-60% before analysis begins. The extraction method is the real variable.

How formalin-fixed paraffin-embedded tissue archives hold enormous potential for single-cell genomics, and how the Singulator 200+ automates the nuclei extraction workflow to unlock that potential

Somewhere in your institution, there's a dusty shelf. Sitting on it: thousands of tissue blocks. Each one holds decades of clinical history. Patient outcomes. Treatment responses. Disease progression. Data that took years to collect. And can you blame researchers for walking past it?

Here's a weird fact: the same chemical that saves your sample also traps everything useful inside it. Think about laminating a document. Great for protection. Terrible if you need to edit what's inside. That's formalin. And for decades, nobody could undo the damage.

Third try. Third failure. The fume hood is running. The xylene smells terrible. And the protocol that worked last Tuesday is giving nothing but debris. Sound familiar? Here's the question nobody was asking: Is it your technique—or is it the physics?

What if that two-hour protocol took sixty minutes? What if twelve pipetting steps dropped to four? What if the fume hood became optional? These aren't hypotheticals. This is what purpose-built automation looks like. And the difference isn't just time.

Behind every tissue block is a patient who said yes. Yes to collection. Yes to research. Yes to the hope that their gift might help someone else. They trusted the science. The question now: are the protocols worthy of that trust?
