一般說明

PCR DIG探针合成试剂盒包含碱不稳定性洋地黄毒苷 (DIG)-11脱氧尿苷三磷酸(dUTP)制剂。该试剂盒可方便有效地制备聚合酶链式反应(PCR)所需的高灵敏度DIG标记DNA探针。这一探针可通过PCR方法利用DIG-11dUTP(碱不稳定性)标记。DIG-dUTP:dTTP的比例为1:2。
PCR DIG探针合成试剂盒包含增强高保真DNA聚合酶混合物。这种强大的酶混合物具有校对活性,以10 pg质粒DNA和10 ng基因组DNA为模板,可聚合40 bp至5 kb长的探针。DIG标记探针可稳定储存一年以上。

應用

利用PCR DIG探针合成试剂盒制备的洋地黄毒苷(DIG)标记DNA探针适于检测Southern和Northern杂交中的低(单)拷贝基因mRNA。DIG标记DNA探针也已用于原位杂交过程中的DNA标记。
可根据探针长度调节提供的dUTP-核苷酸混合物浓度。可在琼脂糖凝胶上快速确定标记效果。
可按照包装说明书中的方案,多次抗体剥离和重新检测。
一次PCR标记反应 (50 μl)制备的探针,通常足够用于20 ml杂交溶液。本试剂盒可进行约25次反应(50 μl)。

包裝

1个试剂盒包含6种组分。

品質

每个批次的PCR DIG探针合成试剂盒都在PCR中经过功能呢检测。扩增产品在基因组Southern blot中进行了检测。
在如本包装内插页所描述的PCR条件下,对照反应可生成442bp的扩增产物。由于在PCR过程中DIG-dUTP的多次插入,PCR产物的分子量将会相对于未标记PCR产物略有提高。在将PCR产物杂交至10μg人类基因组DNA后可通过后续的化学发光检测检测到特异性的片段模式。

CRISPR/Cas9 efficiently induces targeted mutations via non-homologous-end-joining but for genome editing, precise, homology-directed repair (HDR) of endogenous DNA stretches is a prerequisite. To favor HDR, many approaches interfere with the repair machinery or manipulate Cas9 itself. Using Medaka we show

Switchgrass (Panicum virgatum), a robust perennial C4-type grass, has been evaluated and designated as a model bioenergy crop by the U.S. DOE and USDA. Conventional breeding of switchgrass biomass is difficult because it displays self-incompatible hindrance. Therefore, direct genetic modifications

In filamentous fungi, secondary metabolism is often linked with developmental processes such as conidiation. In this study we analyzed the link between secondary metabolism and conidiation in the main industrial producer of the β-lactam antibiotic penicillin, the ascomycete Penicillium chrysogenum.

18S non-functional rRNA decay (NRD) eliminates non-functional 18S rRNA with deleterious mutations in the decoding center. Dissociation of the non-functional 80S ribosome into 40S and 60S subunits is a prerequisite step for degradation of the non-functional 18S rRNA. However, the mechanisms
