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® CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular application.
For optimal and reproducible results, BD Horizon Brilliant Stain Buffer should be used anytime BD Horizon Brilliant dyes are used in a multicolor flow cytometry panel. Fluorescent dye interactions may cause staining artifacts which may affect data interpretation. The BD Horizon Brilliant Stain Buffer was designed to minimize these interactions. When BD Horizon Brilliant Stain Buffer is used in in the multicolor panel, it should also be used in the corresponding compensation controls for all dyes to achieve the most accurate compensation. For the most accurate compensation, compensation controls created with either cells or beads should be exposed to BD Horizon Brilliant Stain Buffer for the same length of time as the corresponding multicolor panel. More information can be found in the Technical Data Sheet of the BD Horizon Brilliant Stain Buffer (Cat. No. 563794/566349) or the BD Horizon Brilliant Stain Buffer Plus (Cat. No. 566385).

The ITEM-4 monoclonal antibody specifically binds to the TWEAK Receptor (TWEAK-R/TWEAKR), which is also known as CD266, or Fibroblast growth factor inducible 14 (FGF-inducible 14, FN14). The TWEAK Receptor is a ~14 kDa type I transmembrane protein that is the 12A family member of the tumor necrosis factor receptor superfamily (TNFRSF12A). It is expressed at low levels in a variety of tissues including, heart, placenta, lung, muscle, and pancreas. TWEAK Receptors are relatively highly expressed on HUVEC cells and certain tumor cell lines. TWEAK-induced TWEAK Receptor-mediated signaling can play roles in inflammation, the induction of apoptosis in certain cell types, the proliferation and migration of endothelial cells, and can promote angiogenesis within healthy and diseased tissues, eg, tumors. The ITEM-4 antibody can induce the death of certain TWEAK-sensitive tumor target cell lines. The TWEAK Receptor binds TWEAK (CD255) and can signal intracellularly by interactions with TRAF1, 2, and 3 cytoplasmic proteins leading to NF-κB activation. The ITEM-4 antibody reportedly crossreacts strongly with mouse CD266 as demonstrated by flow cytometric analysis and functional assays.
