Description
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.
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® CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular application.
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 to the dye under optimum conditions and unreacted dye was removed.
1. 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).
2. An isotype control should be used at the same concentration as the antibody of interest.
3. 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.
4. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
5. Alexa Fluor® 488 fluorochrome emission is collected at the same instrument settings as for fluorescein isothiocyanate (FITC).
