Kremen-2 Protein, Human, Recombinant (His)

产品编号 TMPK-01106

Kremen2 (Krm2) plays an important role in embryonic development, bone formation, and tumorigenesis as a crucial regulator of classical Wnt/β-catenin signaling pathway. Compared to para-cancerous tissues, Krm2 was significantly up-regulated in gastric cancer tissues and was positively correlated with the pathological grade of gastric cancer patients. Krm2 can be a potent candidate for designing of targeted therapy. Kremen-2 Protein, Human, Recombinant (His) is expressed in HEK293 mammalian cells with C-His tag. The predicted molecular weight is 37.1 kDa and the accession number is Q8NCW0-1.

实验操作小课堂
常见问题解答
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。
动物实验常用溶解方法?
首先,您需要确认给药剂量、给药方式。对于具体的产品,优先找引用我们产品的文献里的使用方法,再找其他文献里的配方。 如果没有相关的文献,且该化合物的 DMSO 溶解度比较好,我们推荐通用配方: 10% DMSO+40% PEG300+5% Tween-80+45% Saline/PBS/ddH2O。溶剂依次加入,尽量溶解后再加入下一个溶剂。正常鼠建议 DMSO 浓度在 10% 以下,裸鼠体弱鼠等配方的 DMSO 浓度建议在 2% 以下,根据溶液是否澄清,助溶剂 PEG300、Tween-80 的比例可以适当调整。如果有其他助溶剂也可以使用。 以上配方仅供参考,体内配方并不是绝对的,需要根据不同情况进行调整。建议先取少量化合物测试配方,再进行大量配制。配完也可以再使用超声、加热等方式助溶,看看能不能澄清一点。 腹腔注射对粉末的溶解度要求比较高,建议购买盐形式化合物。如果给药剂量比较大,也有报道使用混悬液进行腹腔给药的。 对于灌胃给药,且剂量比较大的情况下,建议用 0.5% CMC-Na 配置成均匀混悬液进行给药。
准备进行动物实验,收到大包装粉末后,如何分装溶解?
根据配制出来的溶液是不是澄清的确定一次性能配多少:如果配制出来是澄清溶液,可以一次性多配制一些,储存于4度冰箱,大概一周配一次,放久了可能会失效;如果配制出来是混悬液,建议每次使用的时候都现配现用。
产品的溶解度是多少?
建议您先查询TargetMol官网、陶术官网,看该抑制剂的产品介绍,找到溶解度信息。如果没有相应信息,建议联系技术对该化合物的溶解度进行测定。
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。

分子量37.1 kDa (predicted). Due to glycosylation, the protein migrates to 50-60 kDa based on Tris-Bis PAGE result.
内毒素< 1 EU/μg by the LAL method.
缓冲液Lyophilized from a solution filtered through a 0.22 μm filter, containing PBS (pH 7.4). Typically, 8% trehalose is incorporated as a protective agent before lyophilization.
复溶方法
Reconstitute the lyophilized protein in distilled water. The product concentration should not be less than 100 μg/ml. Before opening, centrifuge the tube to collect powder at the bottom. After adding the reconstitution buffer, avoid vortexing or pipetting for mixing.
存储
It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots.
运输方式In general, Lyophilized powders are shipping with blue ice.
