IL⁻⁷重组蛋白
IL⁻⁷重组蛋白说明书
▍Backgound
Interleukin⁻⁷ （IL⁻⁷） is encoded by the IL7 gene ａnd secreted by stromal cells in the red marrow ａnd thymus. It binds to the IL⁻⁷ receptor, a heterodimer consisting of IL⁻⁷ receptor alpha ａnd IL-2 receptor gamma chain. IL⁻⁷ stimulates the differentiation of hematopoietic stem cells into lymphoid progenitor cells ａnd also stimulates proliferation of B cells, T cells ａnd NK cells. Murine IL⁻⁷ has approximately 65% amino acid sequence identity with human IL⁻⁷ ａnd both proteins exhibit cross-species activity. IL⁻⁷ as an immunotherapy agent has been examined in many human clinical trials for various malignancies ａnd during HIV infection.
▍Source
Recombinant Human IL⁻⁷ is expressed from Escherichia coli. It contains AA Asp 26 - His 177. Predicted molecular mass 20.2 kDa. This protein carries a polyhistidine tag at the N-terminus.
▍Endotoxin
Less than 1.0 EU per µg by the LAL method.

▍Purity
Purity >90% as determined by SDS-PAGE.
▍Formulation
Lyophilized from 0.22 µm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization. Contact us for customized product form or formulation.
▍Reconstitution
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.
▍Storage
For long term storage, the product should be stored at lyophilized state at -20°C or lower.
Please avoid repeated freeze-thaw cycles.
This product is stable after storage at:
-20°C to ⁻⁷0°C for 12 months in lyophilized state;
⁻⁷0°C for 3 months under sterile conditions after reconstitution.
▍SDS-PAGE
Human IL⁻⁷, His Tag on SDS-PAGE under reducing （R） condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 90%.
