PolarScreen™ ER β 竞争剂检测试剂盒为潜在雌激素受体 (ER) β 配体的高通量、基于荧光偏振的筛选提供了一种敏感和高效的方法。该试剂盒以均一混合读数检测形式使用表达昆虫细胞的全长、天然(未标记)人 ER β (A15664) 和一种新型、高亲和力、荧光雌激素配体 (Fluormone™ ES2)。

该试剂盒可产生绿色读数;还可提供“红色”试剂盒 (A15891)。两种试剂盒均适合测定竞争性化合物的 IC50。颜色选择取决于待筛选化合物的光谱特性和可用的仪器。如需其他信息或帮助,请发送电子邮件至 drugdiscoverytech@lifetech.com。

PolarScreen™ ER β 竞争剂检测试剂盒:

•全套 & 即用型盒装—包括所有试剂,只需添加供试化合物即可
• 在 384 孔板中进行高通量兼容—20 µL 荧光偏振测定
• 便捷—可提供大规格的组分,以满足更大的筛选需求

检测原理
将全长 ER β 添加至荧光雌激素配体中以形成 ER-Fluormone™ ES2 复合物。将该复合物添加至多孔板中的单一供试化合物中。为测定相对亲和力,测定中测量了荧光偏振。竞争性供试化合物将置换 ER β 的 Fluormone™ ES2 配体,使其能够迅速翻转且产生的偏振值较低。在存在供试化合物的情况下,荧光偏振值的偏移可用于测定供试化合物对 ER β 的相对亲和力。

所有组分均按照极为严格的质量参数生产。根据分析证书,本产品的性能保证在购买后 6 个月内有效。如需大包装规格或帮助满足从检测方法开发到文库筛选等其他核受体检测需求,请联系我们。

What are the common issues encountered with FP assays?

-No assay window: Check that your instrument is designed to do FP experiments.
-Poor discrimination between the minimum and maximum mP Control (both include the receptor): This may be an indication of the quality of the receptor. Do not make single use aliquots of the receptor or store diluted.
-The type of microplate is critical: Please see if the protocol specifies untreated polystyrene or NBS-coated plates. If the plate binds the fluorescent substrate, it cannot freely rotate and the mP reading will always be high. White plates cannot be used for FP assays. Avoid the use of silanized pipette tips and vials.
-The “No Receptor Control' (free Fluormone/Tracer) should have much higher RFU values compared to buffer alone. If not, there is a problem with the instrument setup or less commonly with the Fluormone/Tracer.
-If the free Fluormone/Tracer mP value is greater than 100 mP or negative, please refer to the user manual for your instrument and reset the G factor.

What is the best type of microplate reader for fluorescence polarization (FP) assays?

For FP assays, plate readers must specifically have FP built in. Please see our instrument compatibility portal (http://www.thermofisher.com/us/en/home/industrial/pharma-biopharma/drug-discovery-development/dd-misc/instrument-compatibility-portal.html).

How can I test the fluorescence polarization (FP) settings of my microplate reader before doing the assay?

We offer a FP One-Step Reference Kit (https://www.thermofisher.com/order/catalog/product/P3088) to detect in green (Ex/Em = 488/535 nm) and red (Ex/Em = 525/590 nm) emission ranges, suitable for the PolarScreen Green and Red Assays. The alternative is to perform the Controls in the respective assay kit prior to performing the actual assay using test compounds.
