CD223 antibodies – functional grade, mouse

CD223 antibodies – functional grade, mouse

Clone: C9B7W
Clone C9B7W recognizes an epitope within the D2 domain of murine CD233, also known as LAG-3, which is a 70 kDa high affinity MHC class II ligand. It is expressed on activated CD4
and CD8
α/β T cells and on a subset of NK cells. It has been reported that in association with the CD3 complex CD223 is a negative regulatory molecule to inhibit TCR-mediated signaling and to regulate homeostatic T cell expansion.


This pure – functional grade antibody is suited for cell culture functional assays, for example, blocking of receptor-ligand binding.

Alternative names

LAG-3, Ly66
