IL-7 Protein, Mouse, Recombinant: Product Information

Purity
> 90 % as determined by SDS-PAGE
Endotoxin
Please contact us for more information.
Activity
Measured in a cell proliferation assay using antibody against CD3-activated human peripheral blood lymphocytes (PBL).
The ED50 for this effect is typically 1.3-5.2 ng/mL.
Protein Construction
A DNA sequence encoding the mouse IL7 (NP_032397.1) (Glu26-Ile154) was expressed and purified with an initial Met.
Accession#
Expressed Host
E. coli
Species
Mouse
Predicted N Terminal
Met
Molecule Mass
The recombinant mouse IL7 consists of 130 amino acids and predicts a molecular mass of 15 KDa. It migrates as an approximately 18 KDa band in SDS-PAGE under reducing conditions.
Formulation
Lyophilized from sterile PBS, pH 7.4.
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.
Shipping
In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.
Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
Stability & Storage
Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃
Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
Reconstitution
A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.

IL-7 Background Information

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.
