Anti Iba1, Rabbit (for Immunocytochemistry)

Iba1(Ionized calcium-binding adapter molecule 1)是分子量约为17 kDa的钙结合蛋白。由于在中枢神经系统中,Iba1在小胶质细胞中特异性表达1),因此被用作小胶质细胞标志物。据报告称,Iba1在静息型小胶质细胞和活化型小胶质细胞中均有表达,但有报告称在活化型小胶质细胞中其表达会有所增加2)。另外,Iba1也会在外周组织的巨噬细胞中表达,被称为AIF-1(同种异体移植物炎症因子1,Allograft inflammatory factor-1)。Iba1在细胞内与F-肌动蛋白结合,发挥着形成肌动蛋白纤维束的作用。这种肌动蛋白纤维束的形成被认为是细胞迁移和吞噬过程中观察细胞膜波动结构形成所必须的3)

抗Iba1,兔源(免疫组化用)在免疫组织染色中可以对小胶质细胞包括突起一并进行染色,因此被世界各地的研究人员作为小胶质细胞标记抗体的标准来使用。

近年来,小胶质细胞因其神经营养和保护作用以及通过产生NO、TNF-α和IL-1β引起的神经损伤作用备受关注。
