Description
The B-D44 monoclonal antibody specifically recognizes CD263 which is also known as, TNF-related apoptosis-inducing ligand receptor 3 (TRAIL Receptor 3/TRAIL-R3), Decoy receptor 1 (DCR1), Lymphocyte inhibitor of TRAIL (LIT), or TRID. CD263 is a glycosylphosphatidylinositol (GPI)-anchored glycoprotein that belongs to the TNF Receptor Superfamily which includes other TRAIL (CD253/APO-2 Ligand) Receptors: CD261 (TRAIL-R1), CD262 (TRAIL-R2), and CD264 (TRAIL-R4). Unlike CD261 or CD262 that contain an intracellular signaling death domain, CD263 (and CD264) lacks a cytoplasmic death domain and is unable to transduce apoptotic signals upon binding TRAIL. CD263 thus serves as a decoy receptor for TRAIL. It functions as a negative regulator of apoptotic signaling by competing with CD261 and CD262 for the binding of TRAIL. Overexpression of CD263 can reportedly attenuate TRAIL-induced apoptosis.
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 Alexa Fluor® 647 under optimum conditions, and unreacted Alexa Fluor® 647 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).

3. The Alexa Fluor®, Pacific Blue™, and Cascade Blue® dye antibody conjugates in this product are sold under license from Molecular Probes, Inc. for research use only, excluding use in combination with microarrays, or as analyte specific reagents. The Alexa Fluor® dyes (except for Alexa Fluor® 430), Pacific Blue™ dye, and Cascade Blue® dye are covered by pending and issued patents.
4. Alexa Fluor® 647 fluorochrome emission is collected at the same instrument settings as for allophycocyanin (APC).
