| Application Notes | Associated with an anti-CD161 or -IL18Ra staining, the 3C10 antibody allows unequivocal identification of MAIT cells. Importantly, the Va7.2 segment can also be used by conventional T cells. Therefore, the 3C10 also stains a subset of conventional CD4 and CD8 T cells. Additional reported applications (for the relevant formats) include: spatial biology (IBEX)3,4. |

| Additional Product Notes | Iterative Bleaching Extended multi-pleXity (IBEX) is a fluorescent imaging technique capable of highly-multiplexed spatial analysis. The method relies on cyclical bleaching of panels of fluorescent antibodies in order to image and analyze many markers over multiple cycles of staining, imaging, and, bleaching. It is a community-developed open-access method developed by the Center for Advanced Tissue Imaging (CAT-I) in the National Institute of Allergy and Infectious Diseases (NIAID, NIH). |
