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 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 CompBead to ensure that BD Comp beads 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).

- This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
- 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.
- Source of all serum proteins is from USDA inspected abattoirs located in the United States.

The R3-5G4 monoclonal antibody specifically binds to Runt-related transcription factor 3 (RUNX3) which is also known as Acute myeloid leukemia 2 protein (AML2), Core-binding factor subunit alpha-3 (CBFA3), and Polyomavirus enhancer-binding protein 2 alpha C subunit (PEBP2aC). RUNX3 is a member of the RUNX transcription factor family which includes RUNX1-3. RUNX3 is a key regulator of gene expression related to the development and differentiation of cells within the nervous and immune systems. In the immune system, RUNX3 is particularly involved in the commitment of CD8+ T cells in the thymus. RUNX3 is highly expressed and essential for the cytotoxic functions of NK cells, peripheral CD8+T cells and CD4+CD8αα intraepithelial lymphocytes in the gut. RUNX3 also plays a role in the differentiation and effector functions of Th1 cells. RUNX3 is activated downstream of the TGF-β signaling pathway and can play a role in tumor suppression. Aberrant expression of RUNX3 has been associated with tumorigenesis including the development of gastric and other cancers.
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.
