Clone OX-41

(RUO)

Immunofluorescent staining of mAb OX-41 on bone-marrow cells. Lewis bone marrow cells were incubated simultaneously with either PE-conjugated mouse IgG2a, κ isotype control mAb G155-178 (Cat. No. 553457, left panel) or PE-conjugated mAb OX-41 (right panel) and FITC-conjugated anti-rat CD11b mAb WT.5 (Cat. No. 554982). For analysis, a gate was drawn to include viable cells only (gate not shown) as determined by propidium iodide staining. Flow cytometry was performed on a BD FACSCalibur™ flow cytometry system.

Product Notices

Since applications vary, each investigator should titrate the reagent to obtain optimal results.

Antibody Details

OX-41

The OX-41 monoclonal antibody specifically reacts with the rat signal-regulatory protein (SIRP). The rat SIRP (CD172) is a 110-120-kDa type 1 transmembrane protein with three extracellular immunoglobulin superfamily domains and two intracellular Immunoreceptor Tyrosinebased Inhibitory Motifs (ITIM). The SIRP ITIMs are phosphorylated in response to activation by growth hormone, epidermal growth factor, and integrin-mediated cell adhesion. The phosphorylated SIRP associates with tyrosine phosphatases SHP-1 and/or SHP-2. In the rat, SIRP is selectively expressed on myeloid cells (monocytes, macrophages, granulocytes, and dendritic cells) and neurons. The ligand for rat SIRP is CD47, which is similar to the interaction of the human homolog SIRPα1 (CD172α) and human CD47. The SIRP/CD47 interaction is thought to be important in maintaining cellular adhesion and possibly promote T-cell activation.

Format Details

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.
