联川生物现推出的特色降解组测序服务,助您快速大规模地筛选出动植物miRNA调控的靶基因,进而加速解析miRNA的生物学功能。
|
一次降解组测序即可鉴定出成百上千条miRNA作用的靶基因,远胜于传统的5’RACE方案。 |
|
提供Q30(PhredScore)以上数据,确保数据分析的准确性。 |
|
拥有自主开发的数据分析软件ACGT301-DEG101,并结合CleaveLand,可靠性已经过大量实验项目检验。 |
|
使用全新优化的文库构建方案使得样本起始量更少、建库步骤更简单、测序读长更长,同时PCR扩增次数和割胶纯化次数更少,因而能够更真实地反映样本降解组的丰度,进一步提高实验数据的准确性。 |

Nucleic Acids Res:使用降解组测序鉴定小鼠miRNA以剪切方式调控的靶基因
本研究中,作者使用降解组测序技术鉴定出成年小鼠组织中16个可能的miRNA剪切靶基因,其中miR-151-5p介导剪切N4BP1和let-7b介导剪切2410001C21Rik是最为显著的。

Plant Mol Biol:胡杨microRNA和靶基因研究
胡杨,是一种典型的湿盐生植物,能忍受荒漠中干旱的环境,对盐碱有极强的忍耐力,是木本植物中研究盐胁迫应答的理想模型。北京林业大学林业育种国家工程实验室的尹伟伦教授和夏新莉教授共同领衔其团队,使用深度测序对盐胁迫处理的胡杨中小RNAome,降解组和转录组进行研究。研究表明,胡杨在盐胁迫下,可以发现一大批新的miRNAs,已知和新的miRNA都能功能性的剪切它们的靶mRNA。详细内容>>

BMC Plant Biology: 二代测序鉴定铝胁迫下野生大豆miRNA及其靶基因
野生大豆(Glycine soja)是世界上种植面积最广的作物之一。相比于栽培大豆,野生大豆能够更好地适应自然环境的胁迫如干旱、碱、盐胁迫。华南农业大学亚热带农业生物资源保护与利用国家重点实验室年海教授领衔的课题组联合使用miRNA测序和降解组测序技术大规模系统地测定了铝胁迫下野生大豆的miRNA表达谱和靶基因及其功能, 为深入理解铝胁迫下miRNA发挥的调控作用提供了重要信息。详细内容>>
