Multicolor flow cytometric analysis of LAG-3 (CD223) expression on unstimulated (Top Plots) and stimulated (Bottom Plots) human peripheral blood lymphocytes. Human peripheral blood mononuclear cells (PBMC) were cultured for 3 days with plate-bound Anti-Human CD3 (Cat. No. 555329; 10 µg/mL for coating) and soluble Anti-Human CD28 (Cat. No. 555725; 1 µg/mL) antibodies, and Human Recombinant IL-2 (Cat. No. 554603; 10 ng/mL). Unstimulated PBMC (from the same donor) and the stimulated PBMC were stained with PE Mouse Anti-Human CD8 (Cat. No. 555367/557086/561949/561950), BD Horizon™ BV421 Mouse Anti-Human CD279 (PD-1) (Cat. No. 562516/565935), and Alexa Fluor® 647 Mouse Anti-Human LAG-3 (CD223) (Cat. No. 565716/565717) antibodies. Two-color flow cytometric contour plots showing the correlated expression of LAG-3 (CD223) versus CD8 (Left Plots), or LAG-3 (CD223) versus CD279 (PD-1) (Right Plots) were derived from gated events with the forward and side light-scatter characteristics of viable unstimulated (Top Plots) or stimulated (Bottom Plots) lymphocytes. Flow cytometric analysis was performed using a BD™ LSR II Flow Cytometer System.

- 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).
- An isotype control should be used at the same concentration as the antibody of interest.
- Alexa Fluor® 647 fluorochrome emission is collected at the same instrument settings as for allophycocyanin (APC).
- Alexa Fluor® is a registered trademark of Molecular Probes, Inc., Eugene, OR.
- The Alexa Fluor®, Pacific Blue™, and Cascade Blue® dye antibody conjugates in this product are sold under license from Molecular Probes, Inc. for research use only, excluding use in combination with microarrays, or as analyte specific reagents. The Alexa Fluor® dyes (except for Alexa Fluor® 430), Pacific Blue™ dye, and Cascade Blue® dye are covered by pending and issued patents.
- Source of all serum proteins is from USDA inspected abattoirs located in the United States.
- 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.

The T47-530 specifically recognizes the Lymphocyte Activation Gene 3 (LAG-3) protein which is also known as, Protein FDC, or CD223. LAG-3 is a ~70 kDa type I transmembrane glycoprotein that belongs to the Ig superfamily and exhibits homology to CD4. LAG-3 is expressed on NK cells, regulatory T cells, and activated conventional T cells with higher expression found on CD8+ T cells compared with CD4+ T cells. LAG-3 is an activation induced cell surface molecule that like CD4, binds MHC class II molecules, but with much higher affinity. This may enable LAG-3 to act as a negative competitor of CD4 for MHC class II ligand binding. LAG-3 may associate with the TCR-CD3 complex to downregulate TCR signal transduction and T cell clonal expansion. In contrast, LAG-3-induced signaling may promote dendritic cell activation.
