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.
Dendritic cell inflammatory protein-1 (DCIP-1)/CXCL3 is also known as MIP2 beta (macrophage inflammatory protein 2 beta), or DCIP1 (dendritic cell inflammatory protein-1) in mouse, CINC2 (cytokineinduced neutrophil attractant 2) in rat, and GRO gamma (growth regulated oncogene gamma) in humans. It is an 8 kDa proinflammatory member of the CXC subfamily of heparinbinding chemokines, also called alpha chemokines. Mature mouse CXCL3 shares 88 % and 57 % amino acid (aa) sequence identity with rat and human CXCL3, respectively. Synonyms: DCIP-1 Murine, CXCL3 Murine
