一般描述
哺乳动物细胞亚细胞蛋白质组的快速、可重复提取
ProteoExtract®亚细胞蛋白质组提取试剂盒（S-PEK）设计用于从贴壁和悬浮生长的哺乳动物细胞中，快速且可重复地提取亚细胞蛋白质组。S-PEK利用了四种选定试剂中某些亚细胞室的不同溶解度。对于贴壁细胞，该程序直接在组织培养皿中进行，无需去除细胞。在亚细胞室的连续提取过程中，细胞或细胞的部分仍然附着在平板上，直到使用适当的提取试剂。因此，可以防止细胞从组织培养板上酶促或机械分离，以及不同亚细胞室的任何混合而导致细胞结构的早期破坏。对于悬浮培养的细胞，提取从温和沉淀和细胞清洗开始。分步提取可从一个样品中提取四种不同的蛋白质组分：
样品大小：3-5x106或25-50 mg组织。

- 细胞质部分(F1)
- 膜/细胞器蛋白质部分(F2)
- 核蛋白部分(F3)
- 细胞骨架部分(F4)
样品大小：3-5x106或25-50 mg组织。
特点和优势
- 从一个样品中逐步提取出四种不同的亚细胞蛋白质组。
- 高重复性
- 的无超速离心步骤
- 快速—仅需2小时，手动操作时间为 45 分钟，
- 即可生产出适合功能研究的蛋白质
组分
洗涤缓冲液、提取缓冲液I、提取缓冲液II、提取缓冲液III、提取缓冲液IV、蛋白酶抑制剂混合物、苯甲酸酶®核酸酶（目录号71206）和用户协议。
警告
毒性：多个毒性值，请参阅MSDS（O）
原理
Calbiochem ProteoExtract亚细胞蛋白质组提取试剂盒用于从贴壁组织培养细胞、悬浮组织培养细胞、冷冻细胞颗粒和碎片组织的胞质、细胞器和膜、细胞核和细胞骨架部分亚细胞提取哺乳动物蛋白质。
制备说明
一次提取所需的试剂盒组件
一次亚细胞提取所需的每种组分的体积取决于起始原料量。
一次亚细胞提取所需的每种组分的体积取决于起始原料量。
合适的样品类型包括：
- 贴壁组织培养细胞
- 混悬培养的组织培养细胞
- 冷冻细胞颗粒
- 碎片组织
储存及稳定性
在执行提取方案之前，所有冷冻缓冲液必须在室温下解冻。将水浴温度设置为25°C将有助于解冻过程。解冻后，轻轻摇动或旋转，充分混合缓冲液。
