Validation Data Gallery

  • 1X10^6 HEK TIM3 transient transfected cells (red) and HEK parental cells were surface stained with 0.5 µg FITC Plus-conjugated TIM3 VHH (FITC-tmt). Cells were not fixed.

  • Live HeLa cells transfected with human TIM-3 were immunostained with FITC Plus-conjugated TIM3 VHH (FITC-tmt,1:1000, green). Cells were fixed and nuclei were stained with DAPI (blue). Epifluorescence images were acquired with 20x objective and post-processed.  Note: Immunostaining with FITC-tmt can also be performed after formaldehyde fixation of the cells.

  • Left: 1x10^6 PHA-treated (3d) human PBMCs were surface stained with 1ug FITC Plus conjugated TIM-3 VHH (FITC-tmt) and CL405 CD3 (CL405-65151). Right: 1x10^6 PHA-treated (3d) human PBMCs were surface stained with 1ug FITC Plus conjugated TIM-3 VHH (FITC-tmt) (red) or unstained (blue). 1X10^6 untreated human PBMCs were surface stained with 1ug FITC Plus conjugated TIM-3 VHH (FITC-tmt) (black dashed). Cells were treated with FC Receptor Block prior to staining. Cells were not fixed. Lymphocytes were gated.

Background TIM3, also known as HAVCR2, is a member of the recently discovered T cell Ig and mucin domain-containing molecule superfamily. TIM3 is a negative regulatory molecule that is important for T cell tolerance and has a crucial role in autoimmunity and T cell exhaustion during chronic viral infection (PMID: 23180819). TIM3 is expressed by T-helper type 1 (Th1) cells, macrophage, monocyte, dendritic cells, CD8+ T cell and other lymphocyte subsets. Galectin-9 is a ligand for TIM3. TIM3-galectin-9 pathway negatively regulates T helper type 1 immunity (PMID: 16286920). TIM3 is a 280-aa membrane protein with a calculated molecular weight of 33 kDa, the higher molecular weights between 50 and 70 kDa detected by this monoclonal antibody probably represent glycosylated TIM3 (PMID: 20107545; 17069754; 11725301).
