Purity: > 85% by SDS - PAGE Format: Liquid. In Phosphate Buffered Saline (pH 7.4) containing 10% glycerol.. Ncr1, as known as natural cytotoxicity triggering receptor 1, is a natural killer cell p46-related protein. This protein, along with NKp30 and NKp44, are activiting receptors that belongs to the natural cytotoxicity receptor family. These receptors are expressed by NK cells in the peripheral blood and spleen expresses NKp46 in both resting and activated states. Also, it may contribute to the increased efficiency of activated NK cells to meditate tumor cell lysis. Recombinant mouse Ncr1, fused to hIgG-His-tag at C-terminus, was expressed in insect cell and purified by using conventional chromatography techniques.
