| 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 IL7R? or ? c chain, the two subunits that constitute the functional IL7 receptor. |
| Recombinant Human IL-7 Protein is expressed from E.coli without tag. It contains Asp26-His177. |

| Lyophilized from 0.22 um filtered solution in 25mM PB, 250mM NaCl (pH 6.8). Normally 8% trehalose is added as a protectant before lyophilization. |
|
| Reconstituted protein stable at -80 C for 12 months, 4 C for 1 week. Use a manual defrost freezer and avoid repeated freeze-thaw cycles. |
|
| Shipped at ambient temperature. |
|
| Centrifuge tubes before opening. Reconstituting to a concentration of more than 100 ug/ml is recommended. Dissolve the lyophilized protein in 25mM PB, 250mM NaCl (pH 6.8). |
