Informations générales

LAG-3, also known as CD223, is an immune checkpoint molecule that regulates both T-cell activation and homeostasis. LAG-3 is expressed on activated T cells, NK cells, regulatory T cells, and plasmacytoid dendritic cells. It is a CD4-related molecule that binds MHC class II. LAG-3 plays an important role in modulating T cell expansion and function, and blockade of LAG-3 with monoclonal antibodies can augment T cell function. (PMID: 15634887; 21086108; 28783703)

Antibody did not work as expected even using the suggested antigen retrieval. I'll try it again using a different antigen retrieval.

• Applications: Immunofluorescence
• Primary Antibody Dilution: 1:200
• Cell Tissue Type: Brain samples

Eman (Verified Customer) (09-20-2021)

the antibody works very well for WB the recommended dilution is 1:500 to 1:1000 i think we can even dilute it more this antibody is higly recommended

• Applications: Western Blot
• Primary Antibody Dilution: 1:1000 overnight
• Cell Tissue Type: HEK293T cells
