pGL4.36[luc2P/MMTV/Hygro] Vector【子货号:E136A,包装:1 x 20μg,,运保温度:-20℃】
描述:
核受体检测可以通过传统的方法即利用上游带有核受体反应元件的最小启动子载体来完成。您也可以选择病毒元件像小鼠乳腺肿瘤病毒长末段重复启动子来检测雌激素或糖皮质激素的响应( 如pGL4.36)。很多情况下,利用这些方法进行的研究需要选择含有合适的内源核受体的细胞系,就是说每一种核受体的研究可能需要选择不同的细胞系。利用酵母双杂交原理的方法也适用于核受体的研究。核受体配基结合域与GAL4 DNA 结合域相融合,通过上游含有GAL4 上游激活序列的重复片段的最小启动子的萤火虫萤光素酶载体转染至细胞中。配基结合区域会与配基结合形成同源或异源的二聚体,以及与激活因子或抑制因子相互作用。这种单杂交系统可帮助您在很多细胞系中研究您所感兴趣的核受体。
The pGL4.36[luc2P/MMTV/Hygro] Vector contains MMTV LTR (Murine Mammary Tumor Virus Long Terminal Repeat) that drives the transcription of the luciferase reporter geneluc2Pin response to activation of several nuclear receptors such as Glucocorticoid Receptor and Androgen Receptor.luc2Pis a synthetically derived luciferase sequence with humanized codon optimization. Theluc2Pgene also contains hPEST, a protein destabilization sequence. The protein encoded byluc2Presponds more quickly to induction than the protein encoded by theluc2gene. The vector backbone contains an ampicillin resistance gene to allow for selection inE. coliand the mammalian-selectable marker for hygromycin resistance.
