AtlasPlex: Simplifying Protein Multiplexing for Spatial Tissue Mapping

AtlasPlex by Atlas Antibodies simplifies tissue mapping multiplex immunohistochemistry in FFPE samples with a flexible, ready-to-use mIHC assay, delivering up to 5 plex in a single day with unmatched clarity.


AtlasPlex Multiplex IHC: Smarter Spatial Protein Mapping for Modern Research

Spatial biology is moving fast, and researchers need tools that keep up without wrecking their workflows or budgets. AtlasPlex by Atlas Antibodies delivers a streamlined approach to multiplex immunohistochemistry (mIHC), helping labs map protein expression in tissue while preserving context, morphology, and sanity.

Multiplex IHC is no longer a “nice to have.” It’s essential for understanding tumor microenvironments, validating drug targets, and discovering biomarkers that actually matter in real tissue architecture. AtlasPlex brings that capability into everyday lab settings with a customizable, validated, and scalable system designed for real-world research.

Why Multiplex Immunohistochemistry Matters

Traditional IHC gives you one protein at a time. Multiplex immunohistochemistry lets you see multiple proteins simultaneously, revealing how cells interact and how spatial relationships influence disease progression.

AtlasPlex was built to remove common barriers in multiplex workflows such as complex protocols, limited antibody choices, species dependent issues and tissue damage from repeated stripping steps. The result is a flexible mIHC workflow that supports sequential staining without compromising tissue integrity. Explore the customizable kit here:

Technical Advantages of AtlasPlex

AtlasPlex simplifies multiplexing through a sequential staining workflow that preserves tissue morphology. Instead of harsh stripping methods, it uses enzymatic quenching between rounds, enabling detection of up to five targets in FFPE tissue samples.

Key benefits include:

  • Pre-biotinylated primary antibodies for streamlined workflows
  • No secondary antibodies needed
  • Species Independent
  • Tyramide signal amplification (TSA) for high sensitivity
  • Reduced tissue degradation across staining cycles
  • Compatibility with standard fluorescence microscopes

This balance of accessibility and performance makes AtlasPlex a strong fit for labs that want spatial biology insights without relying on expensive high-parameter platforms.

Not a Fixed Panel: A Library of Possibilities

AtlasPlex leverages the same validation pipeline used in the Human Protein Atlas project, one of the world’s most comprehensive resources for protein expression data. With access to over 12,000 validated targets, researchers can design panels tailored to cancer biology, neuroscience, immunology, and beyond.

This deep antibody library means you’re not stuck with generic panels. You can build experiments around your specific research questions, whether that’s mapping immune infiltration in tumors or tracking protein localization in brain tissue.

Browse the Human Protein Atlas to find the antibodies and validation resources you need and order them directly in our webshop.

Applications Across Translational Research

AtlasPlex supports a wide range of spatial biology applications:

  • Cancer research: Map immune and tumor cell interactions to understand treatment response.
  • Biomarker discovery: Identify spatial expression patterns that correlate with disease states.
  • Drug development: Validate targets in relevant tissue environments.
  • Neuroscience: Study protein localization in complex brain tissue.

Because the platform bridges the gap between single-plex IHC and high-parameter spatial systems, it enables more labs to generate meaningful spatial data without major infrastructure changes.

The Future of Spatial Biology Starts Here

Spatial context is becoming the missing link in many biological discoveries. Understanding not just what proteins are present, but where they interact, can unlock new diagnostic markers and therapeutic strategies.

AtlasPlex by Atlas Antibodies delivers a practical path into multiplex immunohistochemistry, combining validated antibodies, customizable panels, and tissue-friendly workflows. For researchers looking to level up spatial protein mapping without adding complexity, it’s a strong move.
