The 10-3.6 monoclonal antibody specifically recognizes the β chain of the I-A[k] MHC class II alloantigen. It cross-reacts with splenocytes from mice of the H-2[f], H-2[r], and H-2[s] haplotypes, from nonobese diabetic (NOD, H-2[g7]) mice, and with lymph node cells of BN, DA, WRA, and WRC rats. Reactivity with other haplotypes (e.g., b, d, p, q) has not been observed. Long-term in vivo treatment with 10-3.6 mAb has been reported to prevent the spontaneous development of autoimmune insulin-dependent diabetes mellitus (IDDM) in female NOD mice.
The antibody was conjugated to BD Horizon™ BUV563 which is part of the BD Horizon Brilliant™ Ultraviolet family of dyes. This dye is a tandem fluorochrome of BD Horizon BUV395 which has an Ex Max of 348 nm and an acceptor dye. The tandem has an Em Max at 563 nm. BD Horizon BUV563 can be excited by the 355 nm ultraviolet laser. On instruments with a 561 nm Yellow-Green laser, the recommended bandpass filter is 585/15 nm with a 535 nm long pass to minimize laser light leakage. When BD Horizon BUV563 is used with an instrument that does not have a 561 nm laser, a 560/40 nm filter with a 535 nm long pass may be more optimal. Due to the excitation and emission characteristics of the acceptor dye, there may be spillover into the PE and PE-CF594 detectors. However, the spillover can be corrected through compensation as with any other dye combination.
