常见问题解答
化合物带有盐酸盐离子、硫酸盐离子等是否和其本身有什么区别?盐形式和游离态有什么区别?
盐和非盐形式化合物的活性分子是一样的,在生物实验中起到的效果也一致,活性和使用方法都是一样的。只是由于呈盐不同,物理性质比如溶解度会有差异。建议您根据溶解、实验需求进行选择。
如何选择某个靶点的特异性或总的抑制剂?特异性和非特异性的区别是什么?
抑制剂按照特异性分为广谱 pan 和特异性 selective 两种。Pan 为某个靶点总的抑制剂,对所有亚型或整个家族的成员都有抑制作用。Selective 抑制剂针对某个蛋白激酶的某个亚型或家族中某个成员抑制率特别高或有特异性抑制作用。 一般评价一个抑制剂的抑制效率主要看 IC50 值,IC50 值越低,说明抑制剂效率越高。建议您根据以上几个特征进行综合选择,也可联系技术帮您推荐相关抑制剂。

缓冲液Lyophilized from a solution filtered through a 0.22 μm filter, containing PBS, pH 7.4. Typically, a mixture containing 5% to 8% trehalose, mannitol, and 0.01% Tween 80 is incorporated as a protective agent before lyophilization.
复溶方法
A Certificate of Analysis (CoA) containing reconstitution instructions is included with the products. Please refer to the CoA for detailed information.
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.
研究背景
Nicastrin (NCST, or NCT), a single-pass membrane glycoprotein that harbors a large extracellular domain, is an essential component of the gamma-secretase complex. Several lines of evidence indicate that the members of these complexes could also contribute to the control of cell death. NCT controls cell death via phosphoinositide 3-kinase/Akt and p53-dependent pathways and that this function remains independent of the activity and molecular integrity of the gamma-secretase complexes. Increasing pieces of evidence have shown that Nicastrin/NCSTN plays a crucial role in gamma-cleavage of the amyloid precursor protein (APP). The glycoprotein Nicastrin is an essential component of the gamma-secretase complex, a high molecular weight complex that also contains the presenilin proteins, Aph-1 and Pen-2. The gamma-secretase complex is not only involved in APP processing but also in the processing of an increasing number of another type I integral membrane proteins. As the largest subunit of the gamma-secretase complex, Nicastrin plays a crucial role in its activation. Inhibition of NCSTN demonstrated an altered gamma-cleavage activity, suggesting its potential implication in developing Alzheimer's disease (AD). Besides, Nicastrin can function to maintain epithelial to mesenchymal transition during breast cancer progression. Anti-nicastrin polyclonal and monoclonal antibodies were able to decrease notch1 and vimentin expression and reduced the invasive capacity of breast cancer cells in vitro.
