常见问题解答
超声应使用什么仪器?
建议使用“超声清洗仪”,不推荐用“超声破碎仪”。
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。
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。
购买多次产品,发现颜色不同,怎么办?
首先请您确认批次,如果是同一个批次产品,请联系技术同事核查产品颜色。如果是不同批次,请您放心,颜色不同可能是生产工艺不同而造成的,生产过程中的操作、温度、时间等因素可能会影响产品的颜色。如果您对该批次有疑虑,可在官网下载相应的质检报告,我们是对产品质量负责的。
抑制剂母液的储存方式?
母液配置完成后,一般储存于 -80℃,可以存 1 年以上。建议多分装几管,避免反复冻融,常用的存于 4 度,可放一周以上。

研究背景
VRK1 is a member of the vaccinia-related kinase (VRK) family of serine/threonine protein kinases. Serine/threonine protein kinases are tumor suppressor that controls the activity of AMP-activated protein kinase family members, thereby playing a role in various processes such as cell metabolism, cell polarity, apoptosis and DNA damage response. VRK1 contains 1 protein kinase domain and localizes to the nucleus. VRK1 gene is widely expressed in human tissues and has increased expression in actively dividing cells, such as those in testis, thymus, fetal liver, and carcinomas. As a serine/threonine kinase, VRK1 phosphorylates 'Thr-18' of p53/TP53 and may thereby prevent the interaction between p53/TP53 and MDM2. Defects in VRK1 are the cause of pontocerebellar hypoplasia type 1 (PCH1), also called pontocerebellar hypoplasia with infantile spinal muscular atrophy or pontocerebellar hypoplasia with anterior horn cell disease. PCH1 is characterized by an abnormally small cerebellum and brainstem, central and peripheral motor dysfunction from birth, gliosis and anterior horn cell degeneration resembling infantile spinal muscular atrophy.
