循环免疫复合物(CIC)的检测方法不下40余种,一般可分为抗原特异性和抗原非特异性两类,前者只适用于检测已知抗原和其相应抗体的 CIC,后者则是利用免疫球蛋白分子在结合抗原以后的物理学和生物学的改变来检测 CIC。由于人体内形成的 CIC 实际上常涉及多种抗原系统,因此临床上多用抗原非特异法。Raji 细胞法以其灵敏、可靠
Cyclic immune complexes (CIC) detection method is no less than 40 species, can generally be divided into antigen-specific and non-antigenic two categories, the former is only applicable to detect the known antigen and its corresponding antibody CIC, the latter is the use of immunization CIC is detected by changes in the physical and biological properties of globulin molecules following antigen binding. As the formation of CIC in humans often involves a variety of antigen systems, so the clinical use of antigen-specific non-specific method. Raji cell method for its sensitive and reliable
