FFPEcap-seq
FFPEcap-seq profiles 5' capped RNAs from formalin-fixed paraffin-embedded (FFPE) clinical specimens to generate sequencing libraries that enable quantitative analysis of mRNA and enhancer RNA from degraded, low-yield RNA.
Key Features:
- Enzymatic Enrichment: Enzymatic enrichment selectively isolates 5' capped RNAs from FFPE-derived RNA.
- Template Switching Technology: Template switching is employed during library preparation to capture transcript 5' ends for sequencing.
- Detection of Enhancer RNAs: Detects enhancer RNAs originating from distal regulatory regions in addition to mRNAs.
- Efficiency and Simplicity: Provides a rapid and straightforward protocol for processing FFPE samples.
Scientific Applications:
- mRNA Expression Profiling: Enables precise mRNA expression profiling from degraded FFPE specimens.
- Regulatory RNA Analysis: Supports detection and study of enhancer RNAs to investigate gene regulation and regulatory networks.
- Cancer Research and Diagnostics: Applies to tumor biology studies and clinical molecular testing using archival FFPE cancer specimens, supporting large-scale studies and personalized medicine approaches.
Methodology:
Enzymatic enrichment of 5' capped RNAs followed by template switching–based library preparation is used to generate sequencing libraries from FFPE-derived RNA.
