Aqueous buffered solution containing ≤0.09% sodium azide.

Preparation And Storage

The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated with R-PE under optimum conditions, and unconjugated antibody and free PE were removed. Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.

Product Notices

  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. Please refer to for technical protocols.
  3. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at
  4. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.

The RIK-2 monoclonal antibody specifically binds to CD253, also known as TRAIL (TNF-Related Apoptosis-Inducing Ligand) and Apo2 ligand (APO-2L). CD253 is a member of the Tumor Necrosis Factor Superfamily and is encoded by the TNFSF10 gene. CD253 is a type II membrane protein that may be expressed as a soluble as well as full-length, cell surface-associated protein. Both surface and soluble forms of TRAIL rapidly induce apoptosis in a wide range of tumor cell lines but not normal tissue. TRAIL is expressed by activated T cells, NK cells, dendritic cells, monocytes and a variety of non-lymphoid cells. TRAIL can bind to and exert apoptosis through DR4 (TRAIL-R1) and DR5 (TRAIL-R2) receptors. It can also bind to decoy receptors, including DcR1/TRID/TRAIL-R3 and DcR2/TRUNDD/TRAIL-R4, and possibly OPG/TNFRSF11B, which may serve to regulate TRAIL activity. TRAIL has been shown to be involved in T cell-mediated cytotoxicity, but its mechanism of action remains to be fully elucidated. The RIK-2 clone was selected based on its ability to block TRAIL-mediated cytotoxic activity.

R-Phycoerythrin (PE), is part of the BD family of Phycobiliprotein dyes. This fluorochrome is a multimeric fluorescent phycobiliprotein with excitation maximum (Ex Max) of 496 nm and 566 nm and an emission maximum (Em Max) at 576 nm. PE is designed to be excited by the Blue (488 nm), Green (532 nm) and Yellow-Green (561 nm) lasers and detected using an optical filter centered near 575 nm (e.g., a 575/26-nm bandpass filter). As PE is excited by multiple lasers, this can result in cross-laser excitation and fluorescence spillover on instruments with various combinations of Blue, Green, and Yellow-Green lasers. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
