常见问题
非放射性通量分析与膜片钳相比如何？
How does the non-radioactive flux assay compare to patch clamp?
非放射性通量分析被认为是一个高通量的解决方案，以研究广泛的膜蛋白，包括电中性目标，传统的电生理学无法应用。通量分析能够建立与膜片钳相同的药物效力等级。The non-radioactive flux assay is considered a high throughput solution to investigate a broad range of membrane proteins including electro-neutral targets, to which conventional electrophysiology cannot be applied. The flux assay is capable of establishing the same drug potency rank orders as patch clamps.
ICR可以应用于什么类型的膜蛋白靶点？
What type of membrane protein targets can the ICR be applied to?
膜蛋白靶点包括电压门控和配体门控离子通道、共转运蛋白和泵。Membrane protein targets including voltage-gated and ligand-gated ion channels, co-transporters and pumps.
建立通量分析的一般程序是什么？
What is the general procedure of setting up flux assays?
表达感兴趣的离子通道的细胞在被送入ICR之前要经过一系列的程序，包括示踪剂装载、药物孵育、清洗、处理和裂解。ICR可以完全自动化样品分析程序。Cells expressing the ion channels of interest go through a protocol of tracer loading, drug incubation, wash, treatment, and lysis before they are be fed into the ICR. The ICR can fully automate the sample analysis procedure.
ICR 8000和ICR 12000的主要区别是什么？
What are the main differences between the ICR 8000 and ICR 12000?
ICR 8000的最小样品装载量为50 ul，ICR 12000的最小样品装载量为20 ul。ICR 12000每天处理60000孔，而ICR 8000每天处理5000孔。ICR 12000还有一个可选的叠盘机。The minimal sample loading volume is for 50 ul for the ICR 8000 and 20 ul for the ICR 12000. The ICR 12000 has a throughput of processing 60000 wells/day as compared to 5000 wells/day on the ICR 8000. The ICR 12000 also has an optional plate stacker.
什么酶标板与ICR兼容？
