Two-color flow cytometric analysis of Notch4 expression on Mouse splenic dendritic cells. C57BL/6 mouse splenic leucocytes were preincubated with Purified Rat Anti-Mouse CD16/CD32 antibody (Mouse BD Fc Block™) [Cat. No. 553141/553142]. The cells were then stained with APC Hamster Anti-Mouse CD11c (Cat. No. 550261) and BD Horizon™ BUV395 Rat Anti-Mouse CD8a (Cat. No.563786) antibodies and with either PE Hamster IgG1, κ Isotype Control (Cat. No. 553972; Left Plot) or BD Pharmingen™ PE Hamster Anti-Mouse Notch4 antibody (Cat. No. 568785; Right Plot) at 1.0 μg/test. The bivariate pseudocolor density plot showing the correlated expression of Notch4 (or Ig Isotype control staining) versus CD8a was derived from gated CD11c+ events with the forward and side light-scatter characteristics of viable leucocytes. Flow cytometry and data analysis were performed using a BD LSRFortessa™ X-20 Cell Analyzer System and FlowJo™ software. Data shown on this Technical Data Sheet are not lot specific.

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 cell and BD® CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular application.

- 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.
- For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
- Please refer to http://regdocs.bd.com to access safety data sheets (SDS).
- Since applications vary, each investigator should titrate the reagent to obtain optimal results.
- An isotype control should be used at the same concentration as the antibody of interest.

The HMN4-14 monoclonal antibody specifically recognizes an extracellular domain of mouse Neurogenic locus notch homolog protein 4 (Notch4 or Notch 4). Notch4 is a type 1 transmembrane glycoprotein receptor that is encoded by Notch4 (notch 4) which belongs to the Notch family containing four members, Notch1-Notch4. The Notch4 precursor is cleaved in the Golgi and presents as a cell surface heterodimeric receptor. The Notch4 receptor can bind to several membrane-bound ligands from the Delta-like or Jagged family. Upon ligand binding, Notch4 undergoes proteolytic cleavage that results in the release of the Notch intracellular domain, NICD. NICD translocates to the nucleus where it can form a transcriptional activator complex with various transcription factors. These multimeric complexes either positively or negatively regulate the expression of multiple genes including those that orchestrate many facets of embryonic development and the subsequent functioning of organ systems such as the hematopoietic, immune, nervous, and cardiovascular systems. Notch4 is reportedly expressed on CD8+ splenic dendritic cells, endothelial cells, and macrophages. It is weakly expressed on some CD4+CD8+ thymocytes but is not expressed on mature peripheral T cells.
