Anti-Human CD261/DR4 (DR-4-02) ColorWheel^® Dye-Ready mAb

ColorWheel^® technology is a novel and proprietary method of creating your own antibody and dye combinations for use in flow cytometry. By incubating any ColorWheel^® antibody with any ColorWheel^® dye, researchers can quickly and simply produce primary conjugated antibodies for use in single color or multicolor flow cytometry analysis. Each ColorWheel^® antibody and dye is lyophilized for long-term storage, allowing for simplicity and flexibility without compromise. ColorWheel^® technology requires both ColorWheel^® antibody and ColorWheel^® dye for Flow Cytometry application.

Tumor necrosis factor receptor superfamily member 10A (UniProt: O00220; also known as Death receptor 4, TNF-related apoptosis-inducing ligand receptor 1, TRAIL receptor 1, TRAIL-R1, CD261) is encoded by the TNFRSF10A (also known as APO2, DR4, TRAILR1) gene (Gene ID: 8797) in human. CD261/DR4 is a single-pass type I membrane protein, which is synthesized with a signal peptide (aa 1-23) that is subsequently cleaved off to produce the mature protein that contains an extracellular domain (aa 24-239), a transmembrane domain (aa 240-262), and a cytoplasmic domain (aa 263-468). It is widely expressed with high levels observed in spleen, peripheral blood leukocytes, small intestine, and thymus. It is normally present as a monomer but can form homooligomers and heterooligomers with CD261/DR5. Three molecules of CD262/DR4 can also assemble as a homotrimer. TRAIL receptors (DR4 and DR5) induce apoptosis via caspase activation. The adapter molecule FADD is reported to recruit caspase-8 to the activated receptor. The resulting death-inducing signaling complex (DISC) performs caspase-8 proteolytic activation that initiates the subsequent cascade of caspases mediating apoptosis. Both TRAIL-sensitive and TRAIL-resistant breast cancer cell lines can be efficiently killed by overexpression of the CD261/DR4. However, the extent of cell death depends on the strength of the promoter driving DR4 expression. (Ref.: Ramamurthy, V., et al. (2015). Acta Crystallogr. F Struct. Biol.

Clone DR-4-02 is a mouse monoclonal antibody that detects human TRAIL receptor 1 (CD261). It targets an epitope within the extracellular domain.

Lyophilized from PBS containing D-Mannitol and Sucrose, normal appearance is a dried pellet. Reconstituted antibody solution is stable and functional as assessed by functional testing. Contains no biocide or preservatives, such as azide.

1.0 mg/mL after reconstitution at 25 μL in PBS. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

Recommend storage of lyophilized product at 2-8°C. Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial. Reconstitute each vial by adding 25 μL PBS. Protect from light.
