5-plex Immunofluorescence Staining: Deep Spatial Phenotyping with Five-Marker Detection

Overview

5-plex immunofluorescence staining allows for the simultaneous visualization of five distinct protein markers plus DAPI on a single tissue slide. This high-level multiplex IF service is ideal for exploring complex cellular interactions, immune landscape profiling, and spatial biomarker analysis in limited or precious tissue sections.

At iHisto, our advanced 5-plex immunofluorescence service combines TSA (Tyramide Signal Amplification), expert antibody design, and Leica BOND RX automation. We deliver clean, reproducible, and publication-grade results, providing the deep insights required for modern translational research.

How 5-Plex Multiplex IF Staining Works

Our IF stain service utilizes a sophisticated sequential or combined detection strategy to ensure maximum signal clarity across five targets.

Expert Technology: To ensure absolute specificity, iHisto employs a TSA-based sequential detection method. This allows us to use multiple primary antibodies from the same host species while preventing cross-reactivity and amplifying the signal of low-abundance markers.

iHisto Full-Spectrum Fluorophore Panel:

• Green/Cyan: FITC or CYAN

• Orange/Red: CY3 or Texas-Red

• Far-Red: CY5

• Near-Infrared: CY7 (Excellent for reducing tissue autofluorescence)

• Nuclear Counterstain: DAPI (Blue)

Frequently Asked Questions (FAQs)

Q: Can 5-plex be performed on archived FFPE tissue? 

A: Yes. Our immunofluorescence service is fully optimized for FFPE samples using TSA technology to overcome fixative-induced epitope masking.

Q: How do you handle multiple antibodies from the same host in a 5-plex IF service? 

A: We utilize TSA-based sequential detection, which involves stripping the primary/secondary complex after signal amplification, allowing the next antibody to be applied without cross-detection.

Q: Is digital quantification available for five-marker panels? 

A: Absolutely. We offer optional AI-driven spatial analysis to measure co-expression and distance relationships between all five cell populations.
