Isotype IgG2a
Specificity The Ly-6 antigens are a complex collection of determinants, probably coded for by a family of closely linked genes, referred to as Ly6A-E. These antigens have been shown to be differentially expressed on thymocytes, peripheral T and B cells, bone marrow cells, macrophages and neutrophils as well as nonhematopoietic tissues. (4) At present, there is little insight into the function of the products of the Ly-6 locus. (1) However, the antigens have been implicated in playing a role in T cell activation. (1) This mouse Ly6A.2 monoclonal antibody detects the classical Ly-6 alloantigen originally defined with conventional antiserum. (2) Ly6A.2 has been shown to be present on 50-70% of peripheral lymphocytes (including CD4+, CD8+ and B cells), on few thymocytes, all B and T cell blasts and is absent from most bone marrow cells and neutrophils. (2) Ly6A.2 has been located in close proximity to Ly6D.2 on the cell surface, and although related to one another, these two determinants are distinct from Ly6C.2 and Ly6B.2. (2) Thus, although the role of Ly6A.2 is unclear, antibodies to this antigen may be useful tools for separating functionally distinct subpopulations of lymphocytes and resolving pathways of differentiation. In fact, Ly6A.2 is absent from any precursor T cells, but is present on effector T cells. Anti-Ly6A.2 antibodies may also prove useful in T cell activation studies as one of the prominent features of the Ly6A.2 specificity is its anhanced expression following T Cell Activation. (1)
