The NK1.1 (Ly-55), clone PK136, fluorescein (FITC) conjugate is a monoclonal mouse antibody that recognizes the mouse NK1.1 alloantigen. Commonly used, fluorescein conjugates provide relatively high absorptivity, excellent fluorescence quantum yield, and good water solubility.

NK1.1 (Ly-55)
NK1.1, a member of the NKR-P1 family of cell surface receptors, is a type II integral membrane glycoprotein with a C-type lectin domain. It is expressed as a disulfide-linked homodimer on all NK cells, as well as on subsets of thymocytes and peripheral T lymphocytes in selected strains of mice (e.g., C57BL/6, NZB, and CE). NK1.1 mediates cellular activation and differentiation, and is thought to play a role in generating Th2 cells. This antibody does not react with NK cells of BALB/c mice.
