实验操作小课堂
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
Transcobalamin II, also known as TCN2 and TC II, is a plasma protein that binds cobalamin (Cbl; vitamin B12) as it is absorbed in the terminal ileum and distributes to tissues. The circulating transcobalamin II-cobalamin complex binds to receptors on the plasma membrane of tissue cells and is then internalized by receptor-mediated endocytosis. Transcobalamin II is a non-glycolated secretory protein of molecular mass 43 kDa. Its plasma membrane receptor (TC II-R) is a heavily glycosylated protein with a monomeric molecular mass of 62 kDa. Human TCN2 gene is composed of nine exons and eight introns spanning approximately 2 kb with multiple potential transcription start sites. A number of genetic abnormalities are characterized either by a failure to express TCN2 or by synthesis of an abnormal protein. The TCN2 deficiency results in cellular cobalamin deficiency, an early onset of megaloblastic anaemia, and neurological abnormalities.
