产品介绍
超过60%的已知G蛋白偶联受体(GPCR)通过Gq以外的途径发出信号,导致细胞内钙增加。随着基因组学揭示出更多的G蛋白偶联受体靶标,这种趋势持续增加。 Screen Quest 细胞系能够研究通常不通过细胞内钙偶联的GPCR。 Screen Quest 细胞系基于一系列G蛋白嵌合体,包括混杂的G蛋白Gα16。嵌合体由Gq蛋白复合物的α亚基组成,该复合物的5个羧基末端氨基酸已被其他G蛋白之一(Gαs,Gαi,Gαo或Gαz)取代。这些氨基酸负责受体与其G蛋白的偶联。这些嵌合体与特定的非Gq偶联受体共表达可能会在受体刺激后导致细胞内钙信号的产生。 Screen Quest CHO-Ga16-NOP细胞系是用混杂G蛋白Gα16和三种人类阿片受体之一伤害感受器(也称为ORL-1)稳定转染的CHO-K1细胞。细胞中组成型表达的Gα16蛋白使通常通过cAMP途径发挥作用的该受体与Gq信号转导和动员的细胞内钙偶联。可以使用钙敏感染料(例如Calbryte 520 AM,Cal-520 AM,Fluo-8 AM或Fluo-4 AM)和相应的免洗钙试剂盒检测特定配体对这些细胞中阿片样物质/伤害感受器的激活。该细胞系已成功用于药物发现和筛选环境中,以研究通常不通过细胞内钙偶联的GPCR。它已与FLIPR,FDSS系统一起有效使用。金畔生物是AAT Bioquest的中国代理商,为您提供最优质的Screen Quest 人类孤啡肽受体 Ga16 CHO (NOP-Ga16)细胞株。
图示
图1.用Cal-520®,AM(Cat#21130)在CHO-Ga16-NOP细胞中测量了伤害感受肽刺激的钙反应。 将CHO-Ga16-NOP细胞以60,000个细胞/ 100 µL /孔在Costar黑色96孔板中接种过夜。 在含有20 mM Hepes缓冲液(HHBS)的Hanks中,将等体积(100 µL)的10 µMCal-520®AM和2 mM丙磺舒在37°C下孵育1小时。 用具有1 mM丙磺舒的HHBS代替Cal-520®AM上样溶液。 通过FlexStation(分子设备)添加了Nociceptin,以达到最终指示的浓度。 |
