GLCE Protein, Human, Recombinant (His)

产品编号 TMPH-01221

Converts D-glucuronic acid residues adjacent to N-sulfate sugar residues to L-iduronic acid residues, both in maturing heparan sulfate (HS) and heparin chains. This is important for further modifications that determine the specificity of interactions between these glycosaminoglycans and proteins. GLCE Protein, Human, Recombinant (His) is expressed in E. coli expression system with N-6xHis tag. The predicted molecular weight is 70.9 kDa and the accession number is O94923.

实验操作小课堂
常见问题解答
产品溶解需要超声吗?如果没有超声仪怎么办?
超声可以加快粉末的溶解速度,如果您的化合物溶解不了,建议您尝试超声。如果您没有超声仪,建议您选择较低母液浓度,或者较少粉末量,尝试溶解。
产品是否需要避光?
一般来说,如果有需要避光储存的分子,我们会选择棕色玻璃瓶发货的。
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。
得到的杀死细胞的 IC50 与网页上 IC50 差距较大怎么办?
您所测试的IC50是指细胞的增殖抑制实验(半抑制率),细胞增殖抑制实验 IC50值,和网页上的靶点IC50其实是不同的意义。文献里和网页上 IC50其实往往是指对于靶点无细胞实验的抑制率,这样的实验一般是通过激酶或者蛋白纯化实验做出来的,nM 级别的浓度比较常见,但是细胞的增殖抑制实验 IC50 是指细胞的半致死率,同时牵涉到细胞的代谢以及渗透,一般浓度会高一些。 另外,同一个化合物对不同细胞模型的效果也是不同的,建议尝试增加孵育量、延长孵育时间。
母液配置的计算方法?
(1) c=n/v=m/M/v 浓度=物质的量/体积=质量/相对分子质量/体积 (2) 官网产品详情页下方有溶液配制表格,可以参考计算好的加入溶剂体积

存储
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. Solutions are shipping with dry ice.
