Multiplexed immunofluorescence (mIF) imaging has emerged as a powerful approach for spatially resolved, single-cell–level characterization of complex tissues, enabling simultaneous visualization of dozens of protein targets within preserved tissue architecture. Central to the success of mIF experiments is robust antibody panel design, which remains one of the most technically challenging and time-consuming aspects of assay development. Despite rapid advances in imaging platforms, fluorophore chemistry, and signal amplification strategies, many researchers continue to face significant bottlenecks in selecting, validating, and optimizing antibodies for high-plex applications. This webinar will provide a comprehensive overview of the current state of the art in antibody panel design for multiplexed immunofluorescence imaging. Key challenges - including antibody specificity and cross-reactivity, epitope stability across iterative staining cycles, fluorophore selection and spectral overlap, signal dynamic range, tissue-dependent variability, and cumulative assay artifacts - will be discussed in the context of both experimental and analytical constraints. Emphasis will be placed on how design decisions made early in the workflow influence downstream data quality, interpretability, and reproducibility. Attendees will be guided through a systematic framework for rational panel design, from biological question formulation and marker prioritization to antibody screening, titration, and iterative optimization. The webinar will present practical strategies to mitigate common failure points, including approaches for balancing marker abundance, managing steric hindrance, minimizing channel crosstalk, and troubleshooting suboptimal staining patterns. Multiple real-world panel design case studies will be shared to illustrate common pitfalls and effective solutions across different tissue types and experimental goals. The session will lead to a consolidated set of best practices and decision-making guidelines intended to streamline panel development, reduce experimental iteration, and improve robustness across laboratories and platforms. By combining conceptual principles with actionable recommendations, this webinar aims to equip researchers with the tools needed to design, optimize, and deploy high-quality mIF antibody panels with greater confidence and efficiency.
In addition, we will highlight the benefits of using the new Invitrogen™ EVOS™ S1000 Spatial Imaging System for mIF research. This instrument offers a simplified workflow that supports up to 9-plex imaging in a single round, with fast, integrated, automated and reliable unmixing. It is a flexible platform that has compatibility with commonly available labelling methods and dyes, thus expanding the reagent options for panel design and optimization. Examples for using the EVOS S1000 will be offered throughout the webinar to demonstrate its value as attractive tool for advancing research in multiplexed immunofluorescence tissue imaging.
