COMET™ Antibody Validation
COMET™ Antibody Testing Process
IHC serves as the foundational application for spatial biology. While R&D Systems™, by Bio-Techne, IHC-validated antibodies undergo a rigorous validation process before being added to the catalog, we acknowledge that antibody performance can vary across different spatial biology platforms. Ensuring optimal performance requires careful evaluation tailored to each specific application.
R&D Systems antibody validation experts, in collaboration with Lunaphore, have developed a tailored antibody testing process for Lunaphore’s COMET platform. Combining the antibody development and manufacturing expertise of R&D Systems with the spatial biology know-how of Bio-Techne Spatial, ensures that COMET validated antibodies are optimized for performance.
The COMET platform, from Lunaphore, is a fully-automated, high-throughput, spatial biology platform that performs sequential immunofluorescence (seqIF™) through staining, imaging, and elution cycles. It offers the unique flexibility to work with off-the-shelf, non-conjugated primary antibodies.
Streamline Panel Development on COMET™
The antibody testing process for COMET involves several key aspects, with a focus on assessing specificity, sensitivity, and elution efficiency of the primary antibody, using positive control tissue. Our COMET antibody testing process is shown below in Figure 1.

This highlights the antibodies are guaranteed to deliver high-quality and specific staining on the COMET platform. Our COMET validated antibodies are also in the Panel Builder and added to the expanding COMET marker database.

Detection of Cadherin in Human Colon Cancer via Multiplex Immunofluorescence staining on COMET™ using Mouse Anti-Human/Mouse Cadherin Pan Specific Monoclonal Antibody (R&D Systems, Catalog# MAB18385). Tissue was stained using the Alexa Fluor™ 647 Goat anti-Mouse IgG Secondary Antibody (yellow; Bio-Techne Spatial Catalog # DR647MS) and counterstained with DAPI (blue; Bio-Techne Spatial Catalog # DR100). Specific staining was localized to the membrane.
