一般描述

膜联蛋白-V-FLUOS 是一种磷脂结合蛋白,对磷脂酰丝氨酸 (PS) 具有高度亲和力。因此,带膜联蛋白-V 细胞表面PS的检测可作为凋亡细胞的标记。可通过流式细胞术或荧光镜检法进行分析。

特异性

膜联蛋白-V 以 Ca 2 + 依赖性方式结合带负电荷的磷脂表面,并显示对磷脂酰丝氨酸的高度亲和力。

应用

细胞凋亡早期,细胞表面发生改变。其中一种质膜改变是磷脂酰丝氨酸 (PS) 从质膜内部向外层的移位,而PS 由此暴露在细胞外表面。
膜联蛋白-V-FLUOS 通过流式细胞术(FACS) 或荧光镜检法,通过结合凋亡细胞膜外叶上的磷脂酰丝氨酸,检测悬浮细胞中的凋亡细胞。 需要用 碘化丙啶 (PI)(举例来说)进行同时标记,以区分凋亡细胞和坏死细胞。
也可以进行其他二级标记,例如 ,用藻红蛋白或 TRITC 标记的单克隆抗体进行膜表面染色,以进一步确定细胞特征。

制备说明

工作浓度: 建议使用的 rGFP 量:
  • SDS-PAGE(考马斯亮蓝染色):1μg
  • 免疫印迹法:5 ng
储存条件(工作液): 稀释染色液总应新鲜配制。
检测: 膜联蛋白-V-FLUOS 可在 FACS 分析和免疫化学过程中直接检测,无需二次检测系统。
样品材料:细胞系和新鲜分离的细胞。

其他说明

仅用于生命科学研究。不可用于诊断。
