生物活性(Bioactivity)
Measure in a cell proliferation assay using PHA-activated human peripheral blood mononuclear cell (PBMC). The specific activity of GMP Human IL-7 is > 1 × 10^8 IU/mg, which is calibrated against the WHO reference standard (NIBSC code: 90/530) .
制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.

重构方法(Reconstitution)

Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.

存储(Storage)

The product is shipped with ice bag. Store it immediately at -20°C±5°C upon arrival.
-20°C±5°C for 36 months in lyophilized state.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.

背景(Background)

Interleukin (IL)-7 is a non-redundant cytokine in T-cell development and function. It is required in early T-cell development as well as for T-cell homeostasis and is secreted by stromal cells in the thymic and bone marrow (BM) environment. IL-7 binds to its receptor which is composed of the two chains IL-7Rα (CD127), shared with the thymic stromal lymphopoietin (TSLP), and the common γ chain (CD132) for IL-2, IL-15, IL-9 and IL-21. Whereas γc is expressed by most hematopoietic cells, IL-7Rα is nearly exclusively expressed on lymphoid cells. After binding to its receptor, IL-7 signals through two different pathways: Jak-Stat (Janus kinase-Signal transducer and activator of transcription) and PI3K/Akt responsible for differentiation and survival, respectively.
