Product Description |
Recombinant Human IL-7 Protein is expressed from E.coli without tag.It contains Asp26-His177. |
Product Background |
Interleukin-7 (IL7) plays a nonredundant role in T cell survival and homeostasis, which is illustrated in the severe T cell lymphopenia of IL7-deficient mice, or demonstrated in animals or humans that lack expression of either the IL7Rα or γ c chain, the two subunits that constitute the functional IL7 receptor. |
