简单描述

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. The antibody was conjugated to BD Horizon BV421 which is part of the BD Horizon Brilliant™ Violet family of dyes. With an Ex Max of 407-nm and Em Max at 421-nm, BD Horizon BV421 can be excited by the violet laser and detected in the standard Pacific Blue™ filter set (eg, 450/50-nm filter). BD Horizon BV421 conjugates are very bright, often exhibiting a 10 fold improvement in brightness compared to Pacific Blue conjugates.

产品详情

BV421

The BD Horizon Brilliant Violet™ 421 (BV421) Dye is part of the BD Horizon Brilliant Violet™ family of dyes. This polymer-technology based dye has an excitation maximum (Ex Max) of 407-nm and an emission maximum (Em Max) at 423-nm. Driven by BD innovation, BV421 is designed to be excited by the violet laser (405-nm) and detected using an optical filter centered near 420-nm (e.g., a 431/28-nm or 450/50-nm bandpass filter). BV421 is an ideal alternative for V450 as it is approximately ten times brighter with less spillover into the BV510/V500 detector. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.

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 APC Mouse Anti-Human CD8 (Cat. No. 555369/561421/561952/561953), PE Mouse Anti-Human CD279 (PD-1) (Cat. No. 560795), and BD Horizon™ BV421 Mouse Anti-Human LAG-3 (CD223) (Cat. No. 565720/565721) 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.
