Benefits

The MERCURIUS™ Extraction-free Low-input FLASH-seq kits contain all the oligos and enzymes needed to go from low-input RNA samples to sequencing-ready libraries.

Ultra-sensitive: Up to 2x more genes detected than other commercially available solutions. Ideal for rare cell capture.

Dedicated to low-input samples: Low RNA inputs from precious samples (1 pg to 1 ng per well).

Full-length transcript coverage: From differential gene expression to splicing variants and isoform detection.

No need for prior RNA extraction: Simply FACS-sort the cells in the wells containing the buffer for complete lysis and efficient reverse transcription.

One-day lab workflow: Convenient and short protocol from samples to sequencing-ready libraries in only 7H30.

Suited to automation: Enables seamless integration into high-throughput workflows, furter reducing hands-on time and increasing scalability, reproducibility and efficiency.

FAQs

MERCURIUS™ FLASH-seq is a plate-based method that focuses on polyadenylated RNA, which includes most mRNAs. It provides detailed information on gene structure and alternative splicing. Its ability to capture full-length mRNA transcripts and detect low-abundance genes makes it a powerful tool for gene expression profiling.

FLASH-seq protocol was designed to enhance both the sensitivity and efficiency of single-cell mRNA sequencing compared to the most famous plate-based method, Smart-seq2

Read more about the technology in our blog posts: here and here.
We have significantly enhanced the original FLASH-seq method to offer a streamlined workflow and superior data output. This plate-based technology (available in 96- and 384-well formats) features a novel, non-toxic tagmentation buffer and delivers ultra-sensitive gene detection, capturing up to two times more genes compared to other commercially available solutions.
Immunology

FLASH-seq is ideal for studying rare immune cell populations, such as antigen-specific T cells or exhausted T cell subsets in chronic infections and cancer. Its high sensitivity allows researchers to capture subtle transcriptomic differences, splicing events, and even intracellular viral transcripts at the single-cell level.

Cancer
Dissect tumor heterogeneity by sequencing rare cancer stem cells or circulating tumor cells. FLASH-seq enables detection of expressed mutations, splicing isoforms, and gene fusions, providing deep insights into clonal evolution and therapeutic resistance in individual cancer cells.

Neurobiology
In complex tissues like the brain, FLASH-seq empowers researchers to analyze rare neuronal subtypes or glial cells with high resolution. It reveals alternative splicing events and single-nucleotide variants that may be critical in neurodevelopmental or neurodegenerative disorders.

Genetic Therapies & ASOs
FLASH-seq can be used to assess the impact of antisense oligonucleotides (ASOs) on target splicing at single-cell resolution. This enables precise tracking of treatment efficacy across rare or responsive cell subsets within a population.

Intracellular Pathogens
Detect intracellular viral RNA in infected cells—even when those cells are extremely rare. FLASH-seq allows you to simultaneously monitor host responses and viral transcript presence, crucial for studying latent infections or early-stage viral spread.
We require the samples to be added to the lysis buffer that we will ship. The first step is to distribute the buffer in the wells of the dedicated plate(s) that will provide as well. The second step is to add the samples, in the lysis buffer and snap freeze the plates.

Please note! To preserve sample quality during shipping, plates must be placed between dry ice—not just on top. Inadequate cooling may compromise RNA integrity!
