CD265 (RANK) Monoclonal Antibody (R12-31), eBioscience™

Product Specific Information

Description: The R12-31 monoclonal antibody reacts with mouse RANK (Receptor activator of NF-kappaB), a recently cloned member of the TNFR superfamily with no significant homology to other members of this family. RANK ligand (RANKL/TRANCE/ OPGL) binds to RANK on dendritic cells, upregulates the expression of anti-apoptotic protein BcL-XL suggesting a role in dendritic cell survival. The cytoplasmic domain of RANK interacts with TRAF2, TRAF5 and TRAF6. Overexpression of RANK activates NF-kappaB and c-Jun-terminal kinase (JNK) pathways. Recent studies have shown that RANK interaction with TRAF6 activates NF-kappaB, whereas JNK activation is mediated through binding of RANK to TRAF2.

Applications Reported: The R12-31 antibody has been reported for use in flow cytometric analysis.

Applications Tested: The R12-31 antibody has been tested by flow cytometric analysis of mouse RANK transfected cells. This can be used at less than or equal to 1 µg per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.

Purity: Greater than 90%, as determined by SDS-PAGE.

Aggregation: Less than 10%, as determined by HPLC.

Filtration: 0.2 µm post-manufacturing filtered.

Target Information

RANK is a member of the tumor necrosis factor receptor (TNFR) family. The full length mouse RANK cDNA encodes a type I transmembrane protein with an extracellular and a cytoplasmic domain. The extracellular domain contains two potential N-linked glycosylation sites. RANK shares significant amino acid homology with other members of the TNFR family in its extracellular four cysteine-rich repeats. Human and murine RANK share 81% amino acid identity in their extracellular domains.
