常见问题解答
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
抑制剂加 DMSO 配成母液之后,能否放在常温的环境保存1周?
不建议这么做,母液配置好分装保存,建议存于 -20℃ 或 -80℃,尽量避免反复冻融。如果您订购的规格很大,可以考虑分装粉末保存,固体粉末是比较稳定的,-20℃ 可以保存三年。
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。
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。
抑制剂能否用于细胞实验?
可以的,我们的抑制剂都可以用于细胞/体外实验。但有些化合物还没有用于细胞实验的文献,这种情况下,建议您先做预实验,确保研究的可行性。

缓冲液Lyophilized from sterile 25 mM Sodium Citrate, 200 mM NaCl, 0.02% Tween 80, pH 6.0. Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hardcopy of datasheet or the lot-specific COA.
复溶方法
Please refer to the lot-specific COA.
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
Periostin ( POSTN ), also known as OSF2 (osteoblast specific factor 2), is a heterofunctional secreted extracellular matrix (ECM) protein comprised of four fasciclin domains that promotes cellular adhesion and movement, as well as collagen fibrillogenesis. Postn is expressed in unique growth centers during embryonic development where it facilitates epithelial-mesenchymal transition (EMT) of select cell populations undergoing reorganization. In the adult, Postn expression is specifically induced in areas of tissue injury or areas with ongoing cellular re-organization. In the adult heart Postn is induced in the ventricles following myocardial infarction, pressure overload stimulation, or generalized cardiomyopathy. Although the detailed function of Postn is still unclear, Postn-integrin interaction is thought to be involved in tumor development. Postn is frequently overexpressed in various types of human cancers, stimulating metastatic growth by promoting cancer cell survival, invasion and angiogenesis, and can be a useful marker to predict the behavior of cancer.
