Area of Science:

  • Biomedical Imaging
  • Molecular Pathology
  • Immunohistochemistry

Background:

  • Multiplex immunofluorescence (mIF) enables spatial analysis of multiple protein biomarkers in single tissue sections.
  • Existing mIF technologies often compromise sensitivity or throughput, hindering the detection of low-abundance biomarkers.
  • This limitation is critical for comprehensive analysis of complex biological samples.

Purpose of the Study:

  • To introduce a new mIF approach overcoming sensitivity-throughput tradeoffs.
  • To enable high-quality, high-multiplexing, and high-throughput tissue analysis.
  • To facilitate the detection of multiple biomarkers for deeper biological insights.

Main Methods:

  • Utilized DNA barcodes conjugated to antibodies for amplification via single-molecule amplification.
  • Employed sequential detection cycles of fluorescently labeled oligonucleotides to visualize biomarkers.
  • Integrated automated tissue preparation, signal amplification, iterative imaging, and AI-enhanced spatial analysis.
  • Applied the protocol to formalin-fixed, paraffin-embedded (FFPE) multi-tissue micro-arrays (TMAs).

Main Results:

  • Achieved staining quality comparable to clinical-grade immunohistochemistry (IHC).
  • Enabled detection of eight or more biomarkers per sample with high multiplexing.
  • Demonstrated high-throughput whole-slide imaging capabilities.
  • Successfully applied to FFPE TMAs including tonsil, melanoma, colon, and lymph node tissues.

Conclusions:

  • The developed DNA-barcoded mIF assay overcomes critical limitations in sensitivity, multiplexing, and throughput.
  • This advanced technique provides deeper insights into tumor microenvironment and immune landscape.
  • Facilitates understanding of molecular signatures and therapeutic response biomarkers, advancing precision medicine.
