IL-33 Protein, Cynomolgus, Recombinant (His)

产品编号 TMPK-00163 IL-33 Protein, Cynomolgus, Recombinant (His)

Interleukin-33 (IL-33) is a cytokine belonging to the IL-1 family, playing a role in inflammatory, infectious and autoimmune diseases and expressed in the cellular nucleus in several tissues. High levels of IL-33 are expressed in epithelial barrier tissues and endothelial barriers. ST2 is a receptor for IL-33, expressed selectively on a subset of Th2 cells, mediating some of their functions.

常见问题解答

问Tween-20 可以用 Tween-80 替代吗？

答不建议使用 Tween-20。相较于 Tween-20，Tween-80 的耐受性更好，Tween-80已被用作评估实验药物和毒物的行为影响的工具，且没有明显的副作用。参考文献：Castro CA， Hogan JB， Benson KA， Shehata CW， Landauer MR. Behavioral effects of vehicles: DMSO， ethanol， Tween-20， Tween-80， and emulphor-620. Pharmacol Biochem Behav. 1995 Apr;50(4):521-6.

问如何稀释工作液？

答根据您的工作液浓度，计算母液所需要稀释的倍数和所需母液的体积。建议用水、生理盐水、PBS等溶剂进行稀释，如果是细胞实验，可以使用培养基。取适当的溶剂缓慢加入到母液中，直到达到您的工作液浓度，可以通过涡旋或者移液枪轻轻吹打帮助混匀。我们的化合物大部分是脂溶性的，所以在使用 PBS 或者培养基等稀释工作液的时候，会有沉淀析出，这些都是正常现象，大多时候可以通过超声完全溶解。工作液建议现配现用！

问小规格产品，收到瓶子后看不到任何东西？

答由于产品规格小，粉末在运输过程中产生的静电导致过于分散，管壁和盖子上皆会粘着，您可以放心，离心后加入适量溶剂直接配制母液、充分溶解即可。

问PEG300 可以用 PEG400 替代吗？

答PEG300 具有适度的粘稠度，有利于药物的溶解和给药过程，同时也能够提供良好的耐受性，不会对动物造成不良影响。PEG400 可以替代 PEG300。 PEG600 不是很建议，因为熔点接近常温。

问抑制剂能否用于动物实验？

答可以的，我们的抑制剂都可以用于动物/体内实验。但有些化合物还没有用于动物实验的文献，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 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.
