| Introduction | IL-7 is a cytokine important for B and T cell development. This cytokine and the hepatocyte growth factor (HGF) form a heterodimer that functions as a pre-pro-B cell growth-stimulating factor. This cytokine is found to be a cofactor for V(D)J rearrangement of the T cell receptor beta (TCRB) during early T cell development. This cytokine can be produced locally by intestinal epithelial and epithelial goblet cells, and may serve as a regulatory factor for intestinal mucosal lymphocytes. Knockout studies in mice sµggested that this cytokine plays an essential role in lymphoid cell survival. |
| Synonyms | Lymphopoietin 1 (LP-1), pre-B cell factor, IL-7. |
| Source | HEK. |
| Physical Appearance | Sterile Filtered White lyophilized (freeze-dried) powder. |
| Formulation | The IL7 was lyophilized from 1mg/ml in 1xPBS. |
| Solubility | It is recommended to reconstitute the lyophilized IL-7 in sterile PBS containing 0.1% endotoxin-free recombinant HSA. |
| Stability | Lyophilized IL-7 althoµgh stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IL7 should be stored at 4°C between 2-7 days and for future use below -18°C.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles. |
| Purity | Greater than 95% as obsereved by SDS-PAGE. |
| Biological Activity | The activity was determined by the dose dependent stimulation of the proliferation of murine 2E8 cells and is typically 0.6ng/ml corresponding to a specific activity of 1,666,667units/mg. |
| Usage | NeoScientifics products are furnished for LABORATORY RESEARCH USE ONLY. The product may not be used as drµgs, agricultural or pesticidal products, food additives or household chemicals. |
