品牌介绍
Isotype Control
同型对照
同型对照(Isotype Control),使用与一抗相同种属来源、相同亚型、相同剂量和相同的免疫球蛋白及亚型的免疫球蛋白,用于消除由于抗体非特异性结合到细胞表面而产生的背景染色。
同型对照
同型对照的主要目的是确定一抗的结合是特异性的,而不是非特异性的Fc受体或与其他蛋白的相互作用。还可以用来竞争性的结合抗体,与功能阻断抗体发挥同样的功能。
同型对照要与一抗的来源,Ig分型和标记完全一致。
如果一抗是多抗,可以用an normal serum(与一抗相同的正常血清) (must be the same
species as primary antibody)。This control is
easy to achieve and can be used routinely in immunohistochemical staining.这个可以咨询试剂商。同型对照为免疫荧光标记中的阴性对照。由于荧光标记单抗的组来源不同,应选用相同来源的未标记单抗作为同型对照来 调整背景染色。举个例子:比如检测一抗为单抗的mouse anti rat
CD11b,clone OX-42 purified IgG,那么它的isotype 是mouse IgG2a, 所以可以用purified(纯化的) mouse IgG2a来做OX-42的同型对照(Isotype Control)。一般的的生物技术公司和国内的代理都有出售。
同型对照:是指与MoAb相同的、未免疫小鼠的免疫球蛋白亚类,若使用直接免疫荧光染色法,同型对照也应标记荧光色素,如IgG1 FITC、IgG2a、PE等。主要考虑了细胞的自发荧光、FC受体介导的抗体结合和非特异性抗体结合等影响因素。此外,同型对照与MoAb所标记的荧光 色素、浓度、F:P比值(标记的荧光色素与免疫球蛋白分子的比值)应该相同为最佳,这对准确设定阴性与阳性细胞的界标有重要意义,切忌使用与MoAb不相 匹配的同型对照,最好为同一实验室、采用相同工艺或方法制备(如同一品牌)的产品。
