一般描述
eAMV™ 逆转录酶是一种增强型禽成髓细胞病病毒（AMV）逆转录酶，负责合成与 RNA、DNA 或 RNA:DNA 杂交体互补的 DNA 链。这种异常强大的 AMV逆转录酶比标准 AMV 或 Moloney 鼠白血病病毒（M-MLV）逆转录酶具有更优的热稳定性。eAMV™ RT 是从总 RNA 或 poly（A）+RNA获得高质量全长 cDNA 的理想酶，并且在转录长靶标方面也是有效的。
应用
Enhanced Avian Reverse Transcriptase可将RNA转录为DNA，同时显著提升mRNA模板合成cDNA的效率。这是由于本款增强型AMV-RT能够逆转录长链mRNA模板，能够有效穿越复杂的二级结构，可以通过RT-PCR反应检测低丰度mRNA。
增强型禽逆转录酶[eAMV™逆转录酶]已用于总 RNA 的逆转录，以在定量逆转录 PCR（RT-qPCR）分析中合成 cDNA。
生化/生理作用
逆转录酶能够加速dNTP形成磷酸二酯键，从而催化RNA模板整合到互补DNA中。
特点和优势
- 对低丰度信使核糖核酸的敏感性更高
- 在高温（高达 65°C）下通过复杂二级结构进行的无核转录
- 高效生成高达 14.1kb的全长 cDNA
- 产生可用于 PCR 扩增的第一链 cDNA
包装
提供1管10x反应缓冲液。
单位定义
一单位酶能够以多聚腺苷酸为模板，以12-18的oligo(dT)为引物，在10分钟内将1纳摩TMP整合进TCA沉淀材料中。
