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 BV786 under optimal conditions that minimize unconjugated dye and antibody.

Recommended Assay Procedures

For optimal and reproducible results, BD Horizon Brilliant Stain Buffer should be used anytime two or more BD Horizon Brilliant dyes (including BD OptiBuild Brilliant reagents) 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).

Product Notices

  1. This antibody was developed for use in flow cytometry.
  2. 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.
  3. Researchers should determine the optimal concentration of this reagent for their individual applications.
  4. An isotype control should be used at the same concentration as the antibody of interest.
  5. 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.

2H9

The 2H9 monoclonal antibody specifically binds to the Ephrin Type-B Receptor 2 (EphB2).  EphB2 is a type I transmembrane glycoprotein that belongs to the Eph receptor family of tyrosine kinase receptors. EphB2 serves as a cell surface receptor tyrosine kinase for membrane-anchored ligands referred to as type B ephrins (ephrin-B). The EphB2 receptor can bind to ephrin-B1, ephrin-B2, and ephrin-B3. Transmembrane ephrin-B family members are key regulators of embryogenesis including development of the nervous and vascular systems.  The EphB2 receptor functions as a chemodirectant in regulating cellular migration. EphB2/ephrin-B interactions orchestrate cell positioning by regulating cellular adhesion and repulsion during development, thereby influencing cell fate, morphogenesis and organogenesis. Signaling can occur in a forward pathway when the EphB2 receptor tyrosine kinase is activated by bound ligand and in a reverse pathway when transmembrane ephrin-B ligands are activated by EphB2 receptor-mediated crosslinking.  In the adult body, Eph receptor signaling plays major roles in regulating the architecture and physiology of different tissues under normal as well as disease conditions such as cancer. Ephrin-B1 and ephrin-B2 levels are upregulated in the vasculature during inflammation. Ephrin-B2 molecules that are localized to the luminal endothelial surface can signal through the EphB2 which is expressed by monocytes. This interaction promotes monocyte differentiation into proinflammatory macrophages. In the intestinal epithelium, EphB2/ephrin-B interactions regulate both cell positioning and tumor progression. The differential expression patterns of EphB2 allows for the detection and isolation of various intestinal epithelial cell types. These include intestinal stem cells (ISCs) which express high levels of EphB2. The 2H9 antibody reportedly blocks the interaction of EphB2 with ephrin ligands and crossreacts with mouse EphB2.

The antibody was conjugated to BD Horizon™ BV786 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 786-nm.  BD Horizon BV786 can be excited by the violet laser and detected in a filter used to detect Cy™7-like dyes (eg, 780/60-nm filter).

BV786
The BD Horizon Brilliant Violet™ 786 (BV786) Dye is part of the BD Horizon Brilliant Violet™ family of dyes. This tandem fluorochrome is comprised of a BV421 donor with an Ex Max of 407-nm and an acceptor dye with an Em Max at 786-nm.  BV786, driven by BD innovation, is designed to be excited by the violet laser and detected using a filter, centered near 785 nm (e.g. 780/60 nm bandpass filter).  Please ensure that your instrument’s configurations (lasers and filters) are appropriate for this dye.
