(RUO)

Flow cytometric analysis of Galectin-9 expression by mouse thymocytes. C57BL/6 mouse thymocytes were fixed and permeabilized with BD Cytofix/Cytoperm™ Fixation and Permeabilization Solution (Cat. No. 554722), and stained in BD Perm/Wash™ Buffer (Cat. No. 554723) with either PE Rat IgG2a, κ Isotype Control (Cat. No. 553930; dashed line histogram) or PE Rat Anti-Mouse Galectin-9 antibody (Cat. No. 566027; solid line histogram). The fluorescence histogram showing Galectin-9 expression (or Ig Isotype control staining) was derived from gated events with the forward and side light-scatter characteristics of intact thymocytes. Flow cytometric analysis was performed using a BD FACSCanto™ II Flow Cytometer System.

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.
Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
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.
For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
An isotype control should be used at the same concentration as the antibody of interest.

Antibody Details

RG9-35

The RG9-35 monoclonal antibody specifically binds to Galectin 9 (Gal-9) which is encoded by Lgals9 (lectin, galactose binding, soluble 9). Galectin-9 is expressed within cells and can be conveyed to the cell surface and released in soluble form. It is expressed by various cell types including lymphocytes, thymocytes, macrophages, dendritic cells, astrocytes, mast cells, eosinophils, fibroblasts, epithelial cells, and endothelial cells. Its expression can be induced by cells in response to proinflammatory cytokines or infection by certain viruses. Galectin-9 is a ~ 40 kDa S-type lectin that has two carbohydrate recognition domains (CRDs) and forms homodimers. It binds to β-galactosides and can serve as a ligand for TIM-3 (CD366). Galectin-9 can play multiple roles in innate and adaptive immune responses including the activation of macrophage cytokine secretion and bactericidal functions, promotion of dendritic cell maturation, regulatory T cell expansion, and negative regulation of Th1, Th17, NK, and cytotoxic T cells. The RG9-35 antibody can reportedly block some biological activities of Galectin-9.

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.
