目录号 : GB20150Biotin-16-UTP是一种生物素标记的UTP,用于体外转录制备RNA探针。
Cas No.:280549-77-1 (free acid)
Sample solution is provided at 25 µL, 10mM.
Biotin-16-UTP is a biotin-labeled UTP used for in vitro transcription to prepare RNA probes[1]. Biotin-16-UTP is an active substrate for RNA polymerase and can be incorporated by a variety of RNA polymerases (including SP6, T3, and T7 RNA polymerases) to form labeled RNA[2, 3]. Biotin-16-UTP-labeled RNA can be detected by reporter molecules linked to streptavidin, avidin, or anti-biotin antibodies[4, 5]. Biotin-16-UTP can be used for molecular hybridization and RNA-protein interaction studies[6].

Biotin-16-UTP是一种生物素标记的UTP,用于体外转录制备RNA探针[1]。Biotin-16-UTP是RNA聚合酶的活性底物,能够通过多种RNA聚合酶(包括SP6、T3和T7 RNA聚合酶)掺入以形成标记的RNA[2, 3]。Biotin-16-UTP标记的RNA可以通过连接到链霉亲和素、亲和素或抗生物素抗体的报告分子来检测[4, 5]。Biotin-16-UTP能够用于分子杂交及RNA-蛋白相互作用研究[6]。
本方案仅提供一个指导,请根据您的具体需要进行修改。
1. 溶液配制
(1)储存液:本产品以10mM的储存液形式提供。
注意:未使用的储存液分装后在-20℃或-80°C避光保存,避免反复冻融。
(2)工作液:用实验缓冲液稀释储存液,通常配制成0.5mM的工作浓度。
注意:请根据实际情况调整工作液浓度,现用现配。
2. 用Biotin-16-UTP制备RNA探针[1](来自文献,仅做参考)
(1)模板DNA准备:在0.5mL试管中,将1μg纯化模板DNA或4μL对照DNA加入无菌、不含RNase的焦碳酸二乙酯(DEPC)水中,总样品体积为13μL。
(2)体外转录反应体系配制:对于每份样品,加入2μL 10×脱氧核苷三磷酸混合物、2μL 10×转录缓冲液、1μL Protector RNase抑制剂和2μL RNA聚合酶SP6或RNA聚合酶T7。
(3)标记反应:加入Biotin-16-UTP(终浓度通常为0.5mM),在37°C下孵育2h,制备RNA探针。
(4)终止反应:向每个管中加入2mL无RNase-free-DNase I以除去模板DNA,在37°C下孵育10min。向每个管中加入2mL 0.2M EDTA(pH 8.0)终止DNase I反应。
(5)分离RNA探针:通过氯化锂沉淀法分离RNA探针,并重悬于25μL DEPC水中。
