DNA ligase Protein, Colwellia psychrerythraea, Recombinant (His)

产品编号 TMPH-00425

DNA ligase that catalyzes the formation of phosphodiester linkages between 5'-phosphoryl and 3'-hydroxyl groups in double-stranded DNA using NAD as a coenzyme and as the energy source for the reaction. It is essential for DNA replication and repair of damaged DNA. DNA ligase Protein, Colwellia psychrerythraea, Recombinant (His) is expressed in E. coli expression system with N-10xHis tag. The predicted molecular weight is 42.1 kDa and the accession number is Q47YI0.

实验操作小课堂
常见问题解答
如果低于说明书给出的最高溶解度情况下,产品仍未溶解怎么办?
建议您使用一些辅助溶解方法,如水浴加热至 45℃ 或用超声震荡,加速粉末溶解。
如何设置母液浓度?
母液浓度需低于官网给出的溶解度,在这个范围内,根据工作液浓度设置母液浓度,细胞实验中,建议母液浓度设定在工作液浓度的 1000 倍以上。
抑制剂能否用于动物实验?
可以的,我们的抑制剂都可以用于动物/体内实验。但有些化合物还没有用于动物实验的文献,这种情况下,建议您先做预实验,确保研究的可行性。
是否能直接用缓冲液对抑制剂 DMSO 母液做梯度稀释?
大部分情况下,都是可以溶解的。但有时,有机试剂直接加入水相介质时会析出。建议将抑制剂先以DMSO做梯度稀释,再将经过稀释的抑制剂加入缓冲液或细胞培养基。有些抑制剂甚至只有在其工作浓度下才能溶于水相。 比如细胞实验中希望终浓度为 1 μM 的话,可以把 10 mM 的 DMSO 母液用 DMSO 稀释到 1 mM,再吸 2 μL 加入到 2 mL 的生理盐水/PBS/细胞培液,终浓度即为 1 μM。 为避免药物析出,稀释前,可将母液和培养基 37℃ 预热,避免温度低造成严重析出。若稀释过程中出现化合物析出的情况,建议您采用超声加热的方法使其复溶。
加药后检测结果没有作用,是不是产品质量有问题?
产品质量没有问题,都是经过两次严格质检的,HNMR确定产品结构,HPLC确定化合物纯度。同一个抑制剂由于实验材料(细胞、动物)的不同,IC50 和实验效果也是不一样的,不能照搬文献报道的方法,应该根据自己的实验设立浓度梯度,得到一个最适合的浓度。
