The OX-17 antibody reacts with a non-polymorphic determinant of rat MHC Class II antigen, I-E equivalent. RT1D is found on peripheral B lymphocytes, thymic cortical epithelial and medullary reticular cells, epithelial cells in the adult small intestine, macrophages and dendritic cells in the intestinal lamina propria and Peyer's patches, epithelial and dendritic cells in the kidney, and activated monocytes, but not on thymocyes, erythrocytes, peripheral T cells, or brain. Its expression is upregulated on large-vessel endothelia and a variety of epithelial and glandular cells in the gastrointestinal system of rats treated with IFN-γ.
The antibody was conjugated to BD Horizon™ BV510 which is part of the BD Horizon Brilliant™ Violet family of dyes. With an Ex Max of 405-nm and Em Max at 510-nm, BD Horizon BV510 can be excited by the violet laser and detected in the BD Horizon V500 (525/50-nm) filter set. BD Horizon BV510 conjugates are useful for the detection of dim markers off the violet laser.
