基于邻位连接技术(PLA),Duolink® PLA可实现在单分子水平上内源性检测固定细胞中的蛋白质相互作用、翻译后修饰和蛋白表达水平。

Duolink® flowPLA检测试剂盒可通过流式细胞术灵敏地检测细胞群内蛋白质、蛋白质-蛋白质相互作用和蛋白质修饰。Duolink® flowPLA实验需要固定的悬浮细胞、两种可特异性识别目标蛋白的一抗、一对PLA探针(一个PLUS和一个MINUS)、洗涤缓冲液和Duolink® flowPLA检测试剂盒。flowPLA试剂盒具有5种不同荧光染料:紫色、红色、绿色、橙色或远红外。flowPLA试剂盒包含流式细胞术对结合的PLA探针进行扩增和检测所需的所有试剂。使用标准流式细胞术分析设备进行分析。使用者必须提供固定的细胞悬液、一抗和相应的OLA探针。

遵循Duolink® PLA流式细胞术方案使用本产品。

Many cytokine receptors are cell surface proteins that promiscuously combine to form active signalling homo- or heterodimers. Thus, receptor chain dimerization can be viewed as a direct measure of a high probability of intracellular signalling by specific cytokines. Proximity ligation

Considerations for proper experimental design, preparation and execution of the Duolink® PLA for flow cytometry protocol.

Traditional flow cytometry has been limited in the ability to detect protein-protein interactions and low abundant proteins events — until now. We have combined Duolink® Proximity Ligation Assay (PLA) with flow cytometry in a convenient kit, making the analysis of protein-protein interactions with flow cytometry readouts a reality.

General tips and tricks for proper experiment execution, aid in identifying potential problems, and provide solutions to ensure a successful Duolink® PLA experiment for flow cytometry.
