一般描述

成熟肌动蛋白丝是由两条F-肌动蛋白原丝组成的右旋双螺旋结构。
该抗体对肌动蛋白亚型和各种生物体显示出广泛的反应性。通过利用间接免疫荧光标记技术,该抗体能够对培养细胞中的典型应力纤维进行特异性染色,并且可用作肌动蛋白N-末端区域的探针。
肌动蛋白是一种高度保守的蛋白质,是所有种类细胞中细胞骨架和收缩结构的主要成分。它的含量会随细胞和组织的分化类型和功能状态改变。肌动蛋白具有两种不同聚集状态,即球状或纤维状,并且在脊椎动物中至少有6种不同亚型。肌动蛋白的亚型表现出超过90%的序列同源性,但每种亚型都具有独特的NH2-末端序列。这些亚型包括3种α 肌动蛋白(骨骼肌,心肌,平滑肌)、1种β 肌动蛋白(β-非肌肉)和2种γ 肌动蛋白(γ平滑肌和γ非肌肉)。

特异性

肌动蛋白抗体能够识别位于肌动蛋白N-末端区域的表位。在蛋白质免疫印迹中,该抗体能够特异性标记各种组织和物种中的肌动蛋白(42kDa的条带)。在间接免疫荧光染色和免疫组织化学分析中,它能对培养细胞中的典型应力纤维进行特异性染色。

免疫原

与多抗原肽(MAP)骨架连接的N-末端肌动蛋白肽。

应用

使用按1:8000比例稀释的兔抗肌动蛋白抗体作为一抗,通过蛋白质免疫印迹分析来自E13.5小鼠胚胎的肢体组织的匀浆。
兔抗肌动蛋白(20-33)抗体已被用于蛋白质免疫印迹测定。 本品还可用于免疫组织化学、间接免疫荧光和微阵列分析。

生化/生理作用

肌动蛋白可维持细胞形状并参与胞质分裂。 肌动蛋白提供细胞强度并促进细胞的主动运动。 肌动蛋白对于成熟血小板的形成至关重要。 在没有任何自身免疫性肝病早期证据的原位肝移植中,观察到ACTA1(肌动蛋白,α 1)基因的上调。

外形

溶于0.01M磷酸盐缓冲盐水,pH 7.4,含有15 mM叠氮化钠作为防腐剂。

储存及稳定性

需要连续使用时,可在2-8℃下储存最长一个月。对于更长期的储存,可以冷冻成工作等分试样。不建议重复冷冻和解冻,或储存在“无霜”冰箱中。如果长期储存时出现轻微混浊,使用前通过离心澄清溶液。
