Preparation And Storage
Recommended Assay Procedures
Put all BD® AbSeq Reagents to be pooled into a Latch Rack for 500 µL Tubes (Thermo Fisher Scientific Cat. No. 4900). Arrange the tubes so that they can be easily uncapped and re-capped with an 8-Channel Screw Cap Tube Capper (Thermo Fisher Scientific Cat. No. 4105MAT) and the reagents aliquoted with a multi-channel pipette.
BD® AbSeq tubes should be centrifuged for ≥ 30 seconds at 400 × g to ensure removal of any content in the cap/tube threads prior to the first opening.
Product Notices
- This reagent has been pre-diluted for use at the recommended volume per test. Typical use is 2 µl for 1 × 10^6 cells in a 200-µl staining reaction.
- The production process underwent stringent testing and validation to assure that it generates a high-quality conjugate with consistent performance and specific binding activity. However, verification testing has not been performed on all conjugate lots.
- Please refer to bd.com/genomics-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.
- Source of all serum proteins is from USDA inspected abattoirs located in the United States.

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.
