Invitrogen™ CD223 (LAG-3) Monoclonal Antibody (3DS223H), Alexa Fluor™ 647, eBioscience™, Invitrogen™
Mouse Monoclonal Antibody
Supplier: Invitrogen™ 51223942

Description
Description: This 3DS223H monoclonal antibody recognizes human CD223 also known as Lymphocyte Activation Gene 3 (LAG-3). LAG-3 is a 70-kDa surface glycoprotein belonging to the Ig superfamily with homology to CD4. LAG-3 binds to MHC class II with higher affinity than CD4 and is thought to be involved in the negative regulation of T cell activation and homeostatic proliferation. Surface expression of LAG-3 has been reported on activated T cells (including regulatory T cells) and NK cells. CD8+ T cells usually express LAG-3 at significantly higher levels than CD4+ T cells. Coexpression of LAG-3 and CD49b has been proposed to identify human and mouse Type 1 regulatory T cells (Tr1 cells). This 3DS223H antibody will recognize a formaldehyde-fixed epitope. Applications Reported: This 3DS223H antibody has been reported for use in flow cytometric analysis. Applications Tested: This 3DS223H antibody has been pre-titrated and tested by flow cytometric analysis of stimulated normal human peripheral blood cells. This can be used at 5 μL (0.125 μg) per test. A test is defined as the amount (μg) of antibody that will stain a cell sample in a final volume of 100 μL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. Excitation: 633-647 nm; Emission: 668 nm; Laser: Red Laser
