Regulatory Status Legend
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.
The antibody was conjugated to BD Horizon BV421 which is part of the BD Horizon Brilliant™ Violet family of dyes. With an Ex Max of 407-nm and Em Max at 421-nm, BD Horizon BV421 can be excited by the violet laser and detected in the standard Pacific Blue™ filter set (eg, 450/50-nm filter). BD Horizon BV421 conjugates are very bright, often exhibiting a 10 fold improvement in brightness compared to Pacific Blue conjugates.
BV421 is a polymer-based dye excited by the violet laser and is one of the brightest fluorochromes offered by BD Biosciences. Conjugates are typically 10 times brighter than Pacific Blue™ conjugates and are often as bright as or brighter than PE conjugates. Due to nearly identical excitation and emission properties but different spillover characteristics, BD Horizon BV421, Pacific Blue™, and BD Horizon™ V450 cannot be used simultaneously.

Preparation and Storage
Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.
The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography.
The antibody was conjugated with BD Horizon BV421 under optimum conditions, and unconjugated antibody and free BD Horizon BV421 were removed.

For optimal and reproducible results, BD Horizon Brilliant Stain Buffer should be used anytime two or more BD Horizon Brilliant dyes are used in the same experiment. Fluorescent dye interactions may cause staining artifacts which may affect data interpretation. The BD Horizon Brilliant Stain Buffer was designed to minimize these interactions. More information can be found in the Technical Data Sheet of the BD Horizon Brilliant Stain Buffer (Cat. No. 563794).
