GMP Human IL-7

产品信息(Product Info)
表达区间及表达系统(Source)

Recombinant GMP Human IL-7 is expressed from E.coli without tag.
It contains Asp26-His177 [Accession | P13232].

分子量大小(Molecular Weight)

The protein has a predicted MW of 17.5 kDa same as Bis-Tris PAGE result.

纯度(Purity)

≥ 95% as determined by SEC-HPLC.

内毒素(Endotoxin)

≤ 0.01 EU per μg by the LAL method.

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)

Dissolve the lyophilized protein in distilled water. Please refer to the Certificate of Analysis for detailed instructions.

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.

产品数据(Assay Data)
Bis-Tris PAGE

GMP Human IL-7 on Bis-Tris PAGE under reduced condition.

Cell Based Assay

Measured 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 human IL-7 WHO reference standard (NIBSC code: 90/530) (QC Test).

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.
