The AM64 monoclonal antibody specifically binds to CD130 which is also known as gp130 (Membrane glycoprotein 130), IL6ST (Interleukin-6 signal transducer), and IL6RB/IL-6Rβ (Interleukin-6 Receptor beta). CD130 is a 130 kDa type 1 membrane glycoprotein that belongs to the hemopoietic cytokine receptor superfamily. CD130 serves as a common signaling receptor for several cytokine receptor complexes including those that mediate the biological effects of IL-6, IL-11, IL-27, Cardiotrophin-1 (CT-1), Ciliary neurotrophic factor (CNTF), Leukemia inhibitory factor (LIF), and Oncostatin M (OSM). CD130 is widely expressed on a variety of cell types including T cells, activated B cells, monocytes, plasma cells, and endothelia. The AM64 antibody can be used in flow cytometry, immunoprecipitation, western blot, and immunohistochemistry on frozen sections.
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.
