产品详情

Qproteome FFPE Tissue Kit采用创新的专有试剂,逆转福尔马林固定导致的交联,并提供全长蛋白用于后续分析。

绩效

Qproteome FFPE Tissue Kit通过标准化的实验方案,可从 福尔马林固定、石蜡包埋组织样本中高效纯化蛋白质 。标准化的实验方案确保可重复的蛋白质产量(参见" Standardized and reproducible protein extraction")。使用Qproteome FFPE Tissue Kit得到的蛋白质 产量与冷冻样本的产量相媲美。可用于比较不同组织样本,检测疾病特异性标志物(参见" tissue-specific biomarker identification")。

原理

作为组织学样本制备的标准方法,每年都有几百万的福尔马林固定、石蜡包埋样品被分类并存档。以前,受到组织化学技术的限制,对其研究有限。Qproteome FFPE Tissue Kit打破了这一瓶颈,可高效提取适用于Western印迹、蛋白芯片和质谱分析的全长蛋白,为蛋白质组研究和蛋白表达分析提供了珍贵的资源。第一次,研究人员可在存档福尔马林固定、石蜡包埋组织中研究蛋白和表达路径。可同时应用Probing blots或包含多个抗体的芯片研究蛋白,获得多个蛋白表达谱的详细信息,如信号传导通路。

福尔马林固定会产生化学交联,稳定用于组织研究的样本,但会使后续的蛋白分离(如:通过SDS-PAGE)无法进行。Qproteome FFPE Tissue Kit应用创新的专有化学试剂反转交联过程,确保全长蛋白可应用western印迹或蛋白芯片以及后续的免疫学检测进行分析(参见" Compare FFPE Tissue Samples at the Protein Level")。

程序

将切片脱蜡并在Extraction Buffer孵育中,离心后收集上清获得蛋白质。回收所得的蛋白质和常规蛋白质一样,可直接与样本缓冲液混合,并上样到SDS-PAGE胶上。无需其他昂贵的仪器或处理过程。

应用

Qproteome FFPE Tissue Kit提供了特殊的分析方法,以分析病理学状态已确定的样本,但对其精确的蛋白修饰还未完全了解。这些从一系列处理和不同研究组先代那里传下来的样品,为比较蛋白质组学和生物标记研究提供了丰富的资源。
