BD Pharmingen™ PE Hamster anti-Mouse CD55
Clone RIKO-5 (RUO)
Two-color analysis of CD55 expression on splenic B lymphocytes. C57BL/6 splenocytes were pre-incubated with Mouse BD Fc Block™ purified anti-mouse CD16/CD32 (Cat. No. 553141/553142), stained with FITC anti-mouse CD45R/B220 (Cat. No. 553087/553088) and either PE Hamster IgG3, λ isotype control (Cat. No. 553980, left panel) or PE Hamster anti-Mouse CD55 (Cat. No. 58037, right panel). Dead cells were excluded by staining with propidium iodide (Cat. No. 556463), and the total viable leukocytes are displayed. The data demonstrates that CD55 is expressed on the majority of splenocytes, with the greatest density on B lymphocytes. Flow cytometry was performed on a BD FACScalibur™ flow cytometry system.

Preparation And Storage
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 with R-PE under optimum conditions, and unconjugated antibody and free PE were removed.
Product Notices
- Since applications vary, each investigator should titrate the reagent to obtain optimal results.
- An isotype control should be used at the same concentration as the antibody of interest.
- 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.

Antibody Details
RIKO-5
The RIKO-5 monoclonal antibody specifically recognizes the membrane-associated complement regulator CD55, also known as decay-accelerating factor (DAF). CD55 is expressed on the surface of erythrocytes and most splenic leukocytes, including B and T lymphocytes and CD11b-positive splenocytes, but it is not detected on thymocytes. Immunohistochemical staining (using a different monoclonal antibody) demonstrates that CD55 is expressed on vascular endothelium and many other cells types in a wide variety of organs. In the mouse, there are two isoforms of CD55, transmembrane and GPI-anchored, that are recognized by the RIKO-5 antibody. Both isoforms are able to protect cells from complement attack by inhibiting the deposition of C3 on antibody-sensitized cells, but the RIKO-5 antibody is not able to neutralize this activity. CD97, a member of the EGF-TM7 family that is widely expressed in mouse tissues, is another ligand for CD55.

Format Details
PE
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.
