ABSTRACT:
The invention relates to a method of testing a compound for biological activity, which method comprises providing cells expressing one of the CD94/NKG2 family of receptors, contacting the cells with recombinant HLA-E under binding conditions in the presence of the test compound, and determining whether the presence of the compound affects the binding of HLA-E to the cells. The HLA-E property of binding to CD94/NKG2 receptors on NK cells and a subset of CD8+ T cells is useful for targeting CD94/NKG2+ cells for a variety of purposes such as identification, isolation, killing or inactivation.
