1. Measured by its binding ability in a functional ELISA.
Immobilized human IL7 at 10 μg/ml (100 μl/well) can bind human IL7Ra-Fch (Cat:10975-H03H), The EC50 of human IL7Ra-Fch (Cat:10975-H03H) is 15.2-35.6 ng/ml.
2. Measured in a cell proliferation assay using antibody against CD3-activated human peripheral blood lymphocytes (PBL). The ED50 for this effect is typically 1-10 ng/ml.
A DNA sequence encoding the mature form of human IL7 (Asp26-His177) was expressed with a N-terminal Met.
NP No.

The recombinant human IL7 consists of 153 amino acids and predicts a molecular mass of 17.5 KDa. It migrates as an approximately 19 KDa band in SDS-PAGE under reducing conditions.
Lyophilized from sterile 25mM NaH2PO4, 400mM NaCl, pH 6.8.
Please contact us for any concerns or special requirements.
Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
Please refer to the specific buffer information in the hard copy of CoA.
In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.

IL-7 背景信息

IL7, also known as interleukin 7, is a hematopoietic growth factor which belongs to the IL-7/IL-9 family. It is secreted by stromal cells in the bone marrow and thymus. IL7 stimulates the proliferation of lymphoid progenitors. It is important for proliferation during certain stages of B-cell maturation. IL7 and the hepatocyte growth factor (HGF) form a heterodimer that functions as a pre-pro-B cell growth-stimulating factor. It is found to be a cofactor for V(D)J rearrangement of the T cell receptor beta (TCRß) during early T cell development. IL7 can be produced locally by intestinal epithelial and epithelial goblet cells, and may serve as a regulatory factor for intestinal mucosal lymphocytes.
