溶解方式
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1 % BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20 °C. Further dilutions should be made in appropriate buffered solutions.
缓冲液
Lyophilized from a 0.2 μm filtered concentrated solution in PBS, pH 7.4.
注意事项
Avoid repeated freeze/thaw cycles.
储存条件
4 °C/-20 °C
储存方法
This lyophilized preparation is stable at 2-8 °C, but should be kept at -20 °C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8 °C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20 °C to -70 °C.
Eotaxin also called CCL11 is a CC chemokine that signals through the CCR3 receptor. It is produced by IFN-gamma stimulated endothelial cells and TNF-activated monocytes. Eotaxin selectively chemoattracts eosinophils and along Eotaxin-2 and Eotaxin-3, plays a key role in the regulation of eosinophil recruitment in the asthmatic lung, and in allergic reactions. Synonyms: Eotaxin murine, CCL11 murine
