注意事项
As with any protein, exposing IL-7 recombinant protein to repeated freeze / thaw cycles is not recommended. When working with proteins care should be taken to keep recombinant protein at a cool and stable temperature.
储存条件
-20 °C
储存方法
The recombinant protein is stable for at least 2 years from date of receipt at -20 °C. Reconstituted IL-7 is stable for at least 3 months when stored in working aliquots with a carrier protein at -20 °C.
有效期
24 months

背景
IL-7 is a hematopoietic growth factor which affects primarily early B and T cells. Produced by thymic stromal cells, spleen cells and keratinocytes, IL-7 can also co-stimulate the proliferation of mature T cells in combination with other factors such as ConA and IL-2. Human and murine IL-7 is cross-species reactive. Recombinant rat IL-7 is a 15.0 kDa protein containing 130 amino acid residues.
