Leica Biosystems, a Danaher company and a global leader in anatomic pathology solutions, streamlines multiplex immunofluorescence (IF) for oncology and translational research with the launch of its BOND 4-Plex Fluorescent Detection Kit for research use only (RUO). The new pre-assembled kit empowers researchers to achieve consistent, high-quality results while preserving tissue morphology.
Multiplex-IF enables spatial characterization of the tumor microenvironment, such as assessing coexpression of immune checkpoints (e.g., PD-1/PD-L1) and T-cell markers (e.g., CD3, CD8) within the same tissue section. By allowing the simultaneous detection of multiple biomarkers with high sensitivity and clear spectral separation, multiplex IF provides in-depth insights into tumor biology and immune response.
Traditional workflows often require tedious and extensive reagent preparation, manual steps, and harsh staining conditions that can compromise tissue quality and reproducibility. The Leica Biosystems BOND 4-Plex Fluorescent Detection Kit RUO reduces these barriers with a pre-assembled kit that integrates seamlessly with the Leica Biosystems BOND RX automated stainer.
“Our mission is to empower cancer researchers with innovative tools that provide deeper insights and advance the frontiers of cancer research,” said Karan Arora, Senior Vice President, Advanced Assays, AI, and Pharma Partnerships at Leica Biosystems. “With the 4-plex fluorescent detection kit, we’re removing workflow barriers and enabling scientists to generate reliable, reproducible data, while preserving the integrity of precious tissue samples. This launch highlights our ongoing investment in technologies that drive discovery and translational breakthroughs, providing researchers with advanced tools to expand understanding of the tumor microenvironment.”
Featuring a pre-assembled design, the kit simplifies reagent setup and reduces preparation time, enabling direct loading onto the BOND RX stainer. Standardized protocols minimize variability and human error, supporting consistent results across experiments with reproducible performance. The innovation also helps in preserving both tissue morphology and antigenicity for accurate downstream analysis. This is achieved through the use of a gentle elution buffer that operates at low temperatures, ensuring the tissue’s structural integrity remains intact.
The BOND 4-Plex Fluorescent Detection Kit RUO is now available to research laboratories across the United States, with additional regions anticipated throughout 2026. For more information or to request a demonstration, click here.
