Multiplex Immunofluorescence (mIF) on COMET™

The COMET™ platform, from Lunaphore, a Bio-Techne brand, 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. 

Featured Multiplex IF Antibodies Qualified on COMET™

Detection of beta-Actin in Mouse Stomach viaseqIF™ staining on COMET™

Figure 1: Detection of beta-Actin in Mouse Stomach viaseqIF™ staining on COMET™ using Rat Anti-Mouse beta-Actin Monoclonal Antibody (Catalog #MAB11702) Tissue was stained using the Alexa Fluor™ 555 Goat anti-Rat IgG Secondary Antibody. (Yellow; Lunaphore Catalog # DR555RT) and counterstained with DAPI (blue; Lunaphore Catalog # DR100). Specific staining was localized to the cell membrane

Detection of CD21 in Human Lymph Node via seqIF™ staining on COMET™

Figure 2: Detection of CD21 in Human Lymph Node via seqIF™ staining on COMET™ using Rabbit Anti-Human CD21 Monoclonal Antibody (Catalog # NBP3-20354). Tissue was stained using the Alexa Fluor™ Plus 555 Goat anti-Rabbit IgG Secondary Antibody (Yellow; Lunaphore Catalog # DR555RB) and counterstained with DAPI (blue; Lunaphore Catalog # DR100). Specific staining was localized to the membrane. 

Detection of CD31 in Mouse Thymus via seqIF™ staining on COMET™

Tissue was stained using the Alexa Fluor™ 647 Goat anti-Rat IgG Secondary Antibody (Yellow; Lunaphore Catalog # DR647RT) and counterstained with DAPI (blue; Lunaphore Catalog # DR100). Specific staining was localized to the membrane.

Antibody Testing Process on COMET™

Bio-Techne's antibody validation experts have collaborated and trained alongside Lunaphore's research and development team covering protocols and requirements involved in the antibody validation process on COMET™. This includes the antibody qualification process for protocol optimization, with a focus on assessing specificity, sensitivity, and elution efficiency using positive control tissue. At Bio-Techne, our IHC validated antibodies have already undergone a rigorous process to be added to the catalog.  Antibody qualification process for COMET involves several key aspects as shown in Figure 1.

Multiplex IF (mIF) validated antibodies with a Lunaphore certified badge are taken through the qualification or verification process listed above. This rigorous testing process ensures that antibodies, from R&D Systems™ and Novus Biologicals™, part of Bio-Techne, deliver high-quality and specific staining on the COMET™ platform.  Bio-Techne Lunaphore Certified antibodies are also in the Lunaphore Panel Builder and added to the expanding COMET marker database.
