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.
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. 563794/566349) or the BD Horizon Brilliant Stain Buffer Plus (Cat. No. 566385).
Note: When using high concentrations of antibody, background binding of this dye to erythroid cell subsets (mature erythrocytes and precursors) has been observed. For researchers studying these cell populations, or in cases where light scatter gating does not adequately exclude these cells from the analysis, this background may be an important factor to consider when selecting reagents for panel(s).
Product Notices
- 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.
- Researchers should determine the optimal concentration of this reagent for their individual applications.
- 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 MHD4-46 monoclonal antibody specifically binds to Delta-Like Protein 4 which is also known as Delta4, DLL4, and DL4. Delta-Like Protein 4 is a type 1 transmembrane glycoprotein which belongs to the Delta/Serrate/Jagged Family of Notch receptor ligands. The Notch family of transmembrane receptors and their ligands play key roles in various developmental and postnatal processes by controlling cell-fate decisions. Delta-Like Protein 4 is expressed by vascular endothelial cells within certain normal tissues and tumors. It signals through Notch1 and Notch 4 Receptors and plays a critical role in vascular development and homeostasis. Delta-Like Protein 4 expression is upregulated in response to vascular endothelial growth factor (VEGF) and regulates endothelial cell proliferation during vascular sprouting. Delta-Like Protein 4 is also expressed by activated human monocytes and dendritic cells that have been stimulated with proinflammatory activators such as lipopolysaccharide. Recent evidence suggests that Delta-Like Protein 4 may contribute to the T cell potential of CD34+ cells and to the growth of various tumors, and promote tumor cell infiltration.
The antibody was conjugated to BD Horizon BUV615 which is part of the BD Horizon Brilliant™ Ultraviolet family of dyes. This dye is a tandem fluorochrome with an Ex Max near 350 nm and an Em Max near 615 nm. BD Horizon Brilliant BUV615 can be excited by the ultraviolet laser (355 nm) and detected with a 610/20 filter and a 595 nm LP. Due to the excitation of the acceptor dye by the blue/yellow-green laser line, there may be significant spillover into channels detecting PE-CF594 like emissions (eg, 610/20-nm filter).
