Flow cytometric analysis of CD366 (TIM-3) expressed on activated mouse splenocytes. BALB/c splenic leucocytes were cultured for 4 days in the presence of plate-bound Purified NA/LE Hamster Anti-Mouse CD3e (Cat. No. 553057; 10 μg/ml for coating), soluble Purified NA/LE Hamster Anti-Mouse CD28 (Cat. No. 553294; 2 μg/ml), and Purified NA/LE Rat Anti-Mouse IL-4 (Cat. No. 554432; 1 μg/ml) antibodies. The cells were harvested, preincubated with Purified Rat Anti-Mouse CD16/CD32 antibody (Mouse BD Fc Block™) (Cat. No. 553141/553142), and then stained with BD Horizon™ BV421 Rat Anti-Mouse CD8a antibody (Cat. No. 563898) and either BD Horizon™ PE-CF594 Mouse IgG1, κ Isotype Control (Cat. No. 562292; Left Plot) or BD Horizon PE-CF594 Mouse Anti-Mouse CD366 (TIM-3) antibody (Cat. No. 566998; Right Plot) at 0.5 μg/test. BD Via-Probe™ Cell Viability 7-AAD Solution (Cat. No. 555815/555816) was added to cells right before analysis. A bivariate pseudocolor density plot showing the correlated expression of CD8a versus CD366 (TIM-3) [or Ig Isotype control staining] was derived from gated events with the forward and side light-scatter characteristics of viable (7-AAD-negative) cells. Flow cytometry and data analysis were performed using a BD LSRFortessa™ X-20 Cell Analyzer System and FlowJo™ software. Data shown on this Technical Data Sheet are not lot specific.

Preparation And Storage
Recommended Assay Procedures
BD™ CompBeads can be used as surrogates to assess fluorescence spillover (Compensation). When fluorochrome conjugated antibodies are bound to CompBeads, they have spectral properties very similar to cells. However, for some fluorochromes there can be small differences in spectral emissions compared to cells, resulting in spillover values that differ when compared to biological controls. It is strongly recommended that when using a reagent for the first time, users compare the spillover on cells and CompBead to ensure that BD Comp beads are appropriate for your specific cellular application.
Product Notices
- When excited by the yellow-green (561-nm) laser, the fluorescence may be brighter than when excited by the blue (488-nm) laser.
- Because of the broad absorption spectrum of the tandem fluorochrome, extra care must be taken when using multi-laser cytometers, which may directly excite both PE and CF™594.
- Please observe the following precautions: Absorption of visible light can significantly alter the energy transfer occurring in any tandem fluorochrome conjugate; therefore, we recommend that special precautions be taken (such as wrapping vials, tubes, or racks in aluminum foil) to prevent exposure of conjugated reagents, including cells stained with those reagents, to room illumination.

The 5D12 monoclonal antibody specifically recognizes CD366 which is also known as TIM-3 (T-cell immunoglobulin and mucin domain-containing 3) or T-cell membrane protein 3. TIM-3 is encoded by Havcr2 (hepatitis A virus cellular receptor 2). TIM-3 is a type I transmembrane glycoprotein that belongs to the human TIM family within the immunoglobulin superfamily, having one Ig-like V-type domain in its extracellular region. TIM-3 is expressed on activated monocytes, macrophages, dendritic cells, microglia, and mast cells. It is also expressed on type-1 CD4+ (Th1-like) T cells, CD8+ T cytotoxic cells, regulatory T cells (Treg), and natural killer (NK) cells. TIM-3 functions as an inhibitory receptor which helps cells maintain immunological homeostasis and self tolerance. Crosslinking of cell surface TIM-3 by Galectin-9 binding downregulates Th1-like and CD8+ T cell responses and can promote Treg or myeloid-derived suppressor cells. TIM-3 enables dendritic cells to bind phosphatidyl serine expressed by apoptotic cells and to phagocytize these cells to quell potential inflammation. TIM-3 also binds to the alarmin HMGB1 thereby preventing Toll-like receptor (TLR) by released tumor cell DNA.
This antibody is conjugated to BD Horizon PE-CF594, which has been developed exclusively by BD Biosciences as a better alternative to PE-Texas Red®. PE-CF594 excites and emits at similar wavelengths to PE-Texas Red® yet exhibits improved brightness and spectral characteristics. Due to PE having maximal absorption peaks at 496 nm and 564 nm, PE-CF594 can be excited by the blue (488-nm), green (532-nm) and yellow-green (561-nm) lasers and can be detected with the same filter set as PE-Texas Red® (eg, 610/20-nm filter).
