Preparation And Storage
Recommended Assay Procedures
BD™ CompBeads can be used as surrogates to assess fluorescence spillover (Compensation). When fluorochrome conjugated antibodies are bound to BD CompBeads, they have spectral properties very similar to cells. However, for some fluorochromes there can be small differences in spectral emissions compared to cells, resulting in spillover values that differ when compared to biological controls. It is strongly recommended that when using a reagent for the first time, users compare the spillover on cells and BD CompBead to ensure that BD CompBeads are appropriate for your specific cellular application.
Product Notices
- Researchers should determine the optimal concentration of this reagent for their individual applications.
- The production process underwent stringent testing and validation to assure that it generates a high-quality conjugate with consistent performance and specific binding activity. However, verification testing has not been performed on all conjugate lots.
- An isotype control should be used at the same concentration as the antibody of interest.
- Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.

The 927 monoclonal antibody specifically recognizes CD317 which is also known as Bone marrow stromal antigen 2 (BST2) or Plasmacytoid Dendritic Cell Ag-1 (PDCA-1). CD317 (BST2) is a type II transmembrane glycoprotein that is encoded by Bst2. It is highly expressed on naïve plasmacytoid dendritic cells (pDC) which comprise very small populations within lymphoid and nonlymphoid tissues. pDC are characteristically early responders to viruses through Toll-like receptors (TLR), TLR7 and TLR9. Activated pDC can produce large amounts of proinflammatory cytokines including type I interferons, Interferon-alpha (IFN-α) and Interferon-beta (IFN-β), and are also known as Type I IFN producing cells (IPC). CD317 (BST2) expression can be upregulated on a variety of other cell types following stimulation with type I IFNs and IFN gamma including T cells, B cells, plasma cells, NK cells, CD8+ and CD8- dendritic cells, and cell lines. CD317 (BST2) may play a role in sorting proteins, eg, cytokines, from the Golgi apparatus and the plasma membrane.
The antibody was conjugated to BD Horizon Red 718, which has been developed exclusively for BD Biosciences as a better alternative to Alexa Fluor® 700. BD Horizon Red 718 can be excited by the red laser (628 – 640 nm) and, with an Em Max around 718 nm, it can be detected using a 730/45 nm filter. Due to similar excitation and emission properties, we do not recommend using R718 in combination with APC-R700 or Alexa Fluor® 700.
