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™ BV650 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 650-nm. BD Horizon BV650 can be excited by the violet laser and detected in a filter used to detect APC-like dyes (eg, 660/20-nm filter). Due to the excitation and emission characteristics of the acceptor dye, there will be spillover into the APC and Alexa Fluor® 700 detectors. However, the spillover can be corrected through compensation as with any other dye combination.
