Lumito AB (publ) (“Lumito”) and Atlas Antibodies AB (“Atlas Antibodies”) today announce the publication of a new white paper demonstrating how researchers can simplify immunohistochemistry (IHC) workflows while maintaining high sensitivity, quantitative robustness, and reproducibility. The study shows that direct labelling of biomarkers when combining Lumito’s SCIZYS platform with Atlas Antibodies’ well‑characterised primary antibodies can deliver performance comparable to traditional multi‑step methods, with reduced assay complexity.
For researchers and drug developers, robust and reproducible biomarker data are essential for confident biological interpretation and downstream decision‑making. Traditional indirect IHC workflows rely on multiple antibody incubation steps, which can increase hands‑on time, variability, and background signal. The results presented in this white paper demonstrate that a direct labelling strategy can significantly simplify the workflow, without sacrificing data quality, when supported by a highly sensitive detection system and carefully characterised antibodies.
The study compares indirect IHC labelling strategies to direct labeling with Lumito’s SCIZYS system, using the same primary antibodies from Atlas Antibodies in both workflows. The results demonstrate a strong alignment between the two approaches across multiple biomarkers and tissue types, confirming that simplified direct labelling can achieve quantitative and reproducible biomarker detection suitable for research and translational applications.
SCIZYS is Lumito’s integrated imaging platform for highly sensitive, quantitative detection of protein biomarkers in tissue. It combines UCNP‑based (upconverting nanoparticle) detection reagents with a dedicated whole‑slide imaging system, enabling precise measurement of biomarker expression while effectively eliminating tissue autofluorescence. This allows researchers to generate high‑contrast, quantitative data with improved objectivity, which is particularly valuable when analysing complex tissues such as brain and lymphoid tissue, or when detecting low‑abundance targets including transcription factors like FOXP3 and immune checkpoint proteins such as PD‑1.
”This white paper is clear evidence of the strength of our collaboration with Atlas Antibodies and the performance delivered by the SCIZYS system. Enabling direct labeling without compromising sensitivity or data quality is an important breakthrough that both simplifies workflows and enhances reproducibility. We see great potential for this to create tangible value for both researchers and drug developers”, says Sanna Wallenborg, CEO of Lumito.
Atlas Antibodies’ contribution to the workflow is equally critical. The antibodies used in the study are developed for consistency and characterised across relevant tissue and cell‑based models, supporting reliable target detection and reproducible results. This level of antibody performance enables direct labelling approaches to be applied with confidence, reducing variability and supporting robust quantitative analysis.
“The results show how combining a high‑sensitivity detection platform with well‑characterised antibodies enables reliable biomarker analysis even in simplified IHC workflows. For researchers, this means fewer steps, reduced complexity, and greater confidence in the data generated. We see strong potential for this approach to support consistent and reproducible biomarker assessment across research and translational settings,” says Ingela Hofverberg, CEO of Atlas Antibodies.
