The Anti-Kappa antibody, clone TB28-2, is derived from the hybridization of P3-X63-AG8.653 mouse myeloma cells with spleen cells isolated from CB6F1/J (C57BL/6J × BALB/cJ) mice immunized with human IgG, κ myeloma protein.The Anti-Kappa antibody specifically recognizes kappa (κ) light chains of human immunoglobulins.
The antibody was conjugated to BD Horizon BV750 which is part of the BD Horizon Brilliant™ Violet family of dyes. This dye is a tandem fluorochrome of BD Horizon BV421 with an Ex Max of 405-nm and an acceptor dye with an Em Max at 750-nm. BD Horizon Brilliant BV750 can be excited by the violet laser (405 nm) and detected with a 750/30 nm filter with a 740 nm long pass. Due to spectral differences between labeled cells and beads, using BD™ CompBeads can result in incorrect spillover values when used with BD Horizon BV750 reagents. Therefore, the use of BD CompBeads or BD CompBeads Plus to determine spillover values for these reagents is not recommended.
