一般描述

标记效率:来自1μg 线性模板DNA的约10μg的全长地高辛标记RNA被转录。
检测时间:135分钟
样本材料
线性化质粒DNA:
待转录的DNA将会被克隆至含有SP6,T7或T3 RNA聚合酶启动子并相邻于多接头的合适转录载体的多接头位点。对于“流失”转录本的合成,质粒是通过限制性酶进行线性化的。限制性酶生成的5′-突出应当被使用;3′ 突出应当被避免。线性化的模板DNA应当通过酚氯仿抽提及乙醇沉淀进行纯化,以避免RNase的污染。对于′run around′转录环状质粒DNA会被使用。
PCR产物:
含有RNA聚合酶启动子序列的PCR片段也可被用作转录的模板。推荐在转录之前对PCR片段使用HIghPure柱进行纯化。
通过这种方法,特定长度的DIG标记单链RNA探针通过体外转录被生成。在标准条件下,DIG-11-UTP通过SP6、T7和T3 RNA聚合酶以大约每20到25个核苷酸的间隔插入转录产物中。DIG RNA标记混合物专门设计用于优化转录缓冲液的SP6, T7和T3 RNA聚合酶。
便捷的核苷酸混合物用于基于地高辛-11-UTP的RNA标记

内含物
10x 溶液带有:
10 mM ATP, CTP, GTP (各), 6.5 mM UTP, 3.5 mM DIG-11-UTP.

特异性

热灭活:添加 2 μl 0.2 M EDTA (pH 8.0) 终止反应。

应用

利用SP6,T7及T3 RNA聚合酶通过体外转录而使用地高辛-11-UTP进行RNA标记。DIG标记RNA已用于多种杂交技术:
  • Northern blots
  • Southern blots
  • 斑点印迹
  • 菌斑或克隆提升
  • RNase保护实验
  • 染色体, 细胞, 及组织切片原位

特点和优势

DIG RNA标记混合物专门设计用于来自Roche并配以优化的转录缓冲液的SP6, T7和T3 RNA聚合酶。

质量

经DIG RNA标记试剂盒和DIG核酸检测试剂盒检测的功能。

Somatostatin (SS) and allatostatin-C (ASTC) are structurally and evolutionarily related neuropeptides that act as inhibitory regulators of physiological processes in mammals and insects, respectively. Here, we report the first molecular and functional characterization of SS/ASTC-type signalling in a deuterostome invertebrate-the

Experience-dependent plasticity of the adult visual cortex underlies perceptual learning and recovery of function following central nervous system lesions. To reveal the signal transduction cascades involved in adult cortical plasticity, we utilized a model of remapping of cortical topography following

Post-transcriptional regulatory mechanisms are widely used to control gene expression programs of tissue development and physiology. Controlled 3' poly(A) tail-length changes of mRNAs provide a mechanistic basis of such regulation, affecting mRNA stability and translational competence. Deadenylases are a conserved

Our laboratory and others have shown that overexpression of Dlx5 stimulates osteoblast differentiation. Dlx5(-/-)/Dlx6(-/-) mice have more severe craniofacial and limb defects than Dlx5(-/-), some of which are potentially due to defects in osteoblast maturation. We wished to investigate the
