已知人或多种动物的细胞表面具有不同的Ig受体和/或补体受体,这些受体可与凝聚的或与抗原结合的Ig或补体的某些成分结合,因而亦被用于循环免疫复合物(CIC)的检测和分离,这些方法统称为细胞受体法。这些试验中所用的细胞要求材料易得,个体差异小,惟此二者往往不可兼得,成为细胞受体法中的主要缺点之一。目前所用的细胞来源广泛,种类很多,如人外周血细胞(红细胞、中性粒细胞、淋巴细胞、嗜酸性粒细胞、血小板)、动物正常或肿瘤细胞 It is known that the surface of a cell of a human or a variety of animals has different Ig receptors and / or complement receptors that bind to certain components of the Ig or complement that are aggregated or antigenically bound and are therefore also used for circulating immunity Complex (CIC) detection and separation, these methods collectively referred to as cell receptor method. The cells used in these experiments require materials that are readily available and individual differences are small, but these two often do not qualify as one of the major drawbacks of cellular receptor assays. Currently used in a wide variety of cells, a wide range of, such as human peripheral blood cells (red blood cells, neutrophils, lymphocytes, eosinophils, platelets), animal normal or tumor cells
