由Ｌｙ49Ｃ在细胞免疫调节中传导抑制性信号 ,推测该分子与移植免疫耐受有关。国内外大多数的研究是用单克隆抗体方法检测该分子的膜表达 ,但是试剂价格昂贵 ,且需要特殊实验设备 (如免疫荧光显微镜、流式细胞仪等 ) ,不利于推广应用。我们根据核酸杂交原理 ,从减少组织细胞的 Ly49C in the regulation of cellular immunity conduction inhibitory signal, speculated that the molecular immune tolerance and transplantation related. Most studies at home and abroad use the monoclonal antibody method to detect the membrane expression of the molecule, but the reagents are expensive and require special experimental equipment (eg, immunofluorescence microscopy, flow cytometry, etc.), which is not conducive to the promotion and application. We based on the principle of nucleic acid hybridization, from the reduction of tissue cells
