The antibody recognizes TRAIL R1 (DR4), a human death receptor 4 (468 amino acids) expressed in most human tissues (spleen, peripheral blood leucocytes, thymus) and in a variety of tumour derived cell lines.
Fusion protein (Human) containing the extracellular part of DR4 and the constant part of the heavy chain of human IgG1.
Do not use after expiration date stamped on vial label.
Short term exposure to room temperature should not affect the quality of the reagent. However, if reagent is stored under any conditions other than those specified, the conditions
must be verified by the user.
Soluble antibody blocks DR4 receptor against TRAIL induced apoptosis. Plastic immobilized antibody induces apoptosis in sensitive cells.
The purified antibody is conjugated with Fluorescein isothiocyanate (FITC) under optimum conditions. The reagent is free of unconjugated FITC and adjusted for direct use. No reconstitution is necessary.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use at an assay dependent concentration.
Use a concentration of 2 - 3 µg/ml. in cultivation medium. Final concentration of TRAIL: 20-200 ng/ml. Note: It is recommended that the antibody is added 15 min before the addition of TRAIL.
Use a concentration of 5 µg/ml.
ab91356 - Mouse monoclonal IgG1, is suitable for use as an isotype control with this antibody.
Receptor for the cytotoxic ligand TNFSF10/TRAIL. The adapter molecule FADD recruits caspase-8 to the activated receptor. The resulting death-inducing signaling complex (DISC) performs caspase-8 proteolytic activation which initiates the subsequent cascade of caspases (aspartate-specific cysteine proteases) mediating apoptosis. Promotes the activation of NF-kappa-B.
Widely expressed. High levels are found in spleen, peripheral blood leukocytes, small intestine and thymus, but also in K562 erythroleukemia cells, MCF7 breast carcinoma cells and activated T-cells.
Contains 1 death domain. Contains 3 TNFR-Cys repeats.
