PE Mouse Anti-Human Galectin-9
PE Mouse Anti-Human Galectin-9
Flow cytometric analysis of Galectin-9 expression on human MOLT-4 cells. Cells from the human MOLT-4 (T lymphoblastic leukemia, ATCC CRL-1582) cell line were fixed with BD Cytofix™ Fixation Buffer (Cat. No. 554655) and permeabilized with BD Perm/Wash™ Buffer (Cat. No. 554723). The cells were then stained with PE Mouse IgG1, κ Isotype Control (Cat. No. 554680; dashed line histogram) or PE Mouse Anti-Human Galectin-9 antibody (Cat. No. 565890/565892; 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 MOLT-4 cells. Flow cytometry was performed using a BD FACSCanto™ II Flow Cytometer System.
PE Mouse Anti-Human Galectin-9
Multiparameter flow cytometric analysis of Galectin-9 expression on human peripheral blood mononuclear cells. Human peripheral blood mononuclear cells (PBMC) were fixed with BD Cytofix™ Fixation Buffer (Cat. No. 554655) and permeabilized with BD Perm/Wash™ Buffer (Cat. No. 554723). The cells were then stained with PE Mouse IgG1, κ Isotype Control (Cat. No. 554680; Left Plot) or PE Mouse Anti-Human Galectin-9 antibody (Cat. No. 565890/565892; Right Plot).  Two-parameter flow cytometric contour plots showing the correlated expression of Galectin-9 (or Ig Isotype control staining) versus side light-scatter (SSC-A) signals were derived from gated events with the forward and side light-scatter characteristics of intact leucocyte populations. Flow cytometric analysis was performed using a BD FACSCanto™ II Flow Cytometer 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

  1. This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
  2. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
  3. 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.
  4. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
  5. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
  6. An isotype control should be used at the same concentration as the antibody of interest.

9M1-3

The 9M1-3 monoclonal antibody specifically binds to Galectin-9 (Gal-9) which is encoded by LGALS9 (lectin, galactoside-binding, soluble, 9). Galectin-9 is differentially expressed within or on the surface of various cell types including lymphocytes, macrophages, astrocytes, mast cells, eosinophils, fibroblasts, and endothelial cells. Its expression can be induced by cells in response to proinflammatory cytokines or infection by certain viruses. Galectin-9 is an ~ 50 kDa S-type lectin that has two carbohydrate recognition domains (CRDs). It binds to β-galactosides and can serve as a ligand for TIM-3 (CD366). Cell-surface or released forms of Galectin-9 can play multiple roles in innate and adaptive immune responses including the activation of macrophage cytokine secretion, promotion of dendritic cell maturation and regulatory T cell expansion, and negative regulation of Th1, Th17, NK, and cytotoxic T cells. Galectin-9 may contribute to the survival and growth of some tumors by suppressing anti-tumor immune responses. The 9M1-3 antibody reportedly binds to the CRD2 domain of Galectin-9 and can block its binding to TIM-3.

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.
