Anti-DR5/CD262 Antibody, clone 1B19 ZooMAb^® Rabbit Monoclonal

Tumor necrosis factor receptor superfamily member 10B (UniProt: O14763; also known as Death receptor 5, TNF-related apoptosis-inducing ligand receptor 2, TRAIL receptor 2, TRAIL-R2, CD262) is encoded by the TNFRSF10B (also known as DR5, KILLER, TRAILR2, TRICK2, ZTNFR9) gene (Gene ID: 8795) in human. DR5/CD262 is a single-pass type I membrane protein that is synthesized with a signal peptide (aa 1-55), which is subsequently cleaved off to generate the mature form that contains an extracellular domain (aa 56-210), a transmembrane domain (aa 211-231), and a cytoplasmic domain (aa 232-440). It is a pro-apoptotic member of the tumor necrosis factor receptor superfamily that is constitutively expressed in various tissue types and forms auto-inhibited dimers in its resting state. It is widely expressed in adult and fetal tissues and its higher expression is observed in heart, peripheral lymphocytes, liver, pancreas, spleen, placenta, and throughout the intestinal tract. High expression of DR5/CD262 is also reported in various cancer cell lines. In its resting state, it is a monomeric protein that serves as a receptor for TRAIL (TNFSF10) and mediates apoptotic cell death. In its canonical mode of activation, binding of its ligand TRAIL assembles it into higher-order oligomers that forms intracellular scaffolds in which its cytosolic death domains recruit the adaptor protein FADD and pro-caspase 8 into the death-inducing signaling complex (DISC). Subsequently, pro-caspase 8 undergoes auto-proteolysis to form active initiator caspase 8. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Clone 1B19 is a ZooMAb^® Rabbit recombinant monoclonal antibody that specifically detects Death receptor 5 (DR5/CD262). It targets an epitope within 16 amino acids from the internal region.

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS, 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 μL.

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 of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.

Reconstitute lyophilized antibody pellet with 25μL of ultrapure water or Phosphate Buffered Saline (PBS). Please refer to our reconstitution protocol and the specific application guidance on the suggested starting dilutions and sample type.
