Product Description
Interleukin-4 (IL-4), also known as B cell-stimulatory factor-1, is a pleiotropic cytokine that induces differentiation of naive helper T cells (Th0 cells) to Th2 cells and produced by by mast cells, activated T cells and bone marrow stromal cells. Mature human IL-4 shares 55%, 39% and 43% aa sequence identity with bovine, mouse, and rat IL-4, respectively.It is a potent cytokine produced by T cells and to a lesser extent by tumor-associated natural killer cells, basophils, and mast cells. IL-4 is a differentiation factor for transforming growth factor-beta secreting Th3. And IL-4 activates two distinct signalling pathways through tyrosine phosphorylation of Stat6, a signal transducer and activator of transcription, and of a 170K protein called 4PS.

| Physical Appearance |
Sterile Filtered White lyophilized (freeze-dried) powder. |
| Purity |
> 95% by SDS-PAGE and HPLC analyses. |
| Biological Activity |
Fully biologically active when compared to standard. The ED50 as determined by a cell proliferation assay using rat splenocytes is less than 1.0 ng/mL, corresponding to a specific activity of > 1.0 × 106 IU/mg. |
| Endotoxin |
< 1.0 EU per 1μg of the protein by the LAL method. |
| Formulation |
Lyophilized from a 0.2 μm filtered concentrated solution in PBS, pH 7.4, 5% trehalose. |
| Reconstitution |
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. 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℃. Further dilutions should be made in appropriate buffered solutions. |
Shipping and Storage
The products are shipped with ice pack and can be stored at -20℃ to -80℃ for 1 year.
Recommend to aliquot the protein into smaller quantities when first used and avoid repeated freeze-thaw cycles.
Cautions
Avoid repeated freeze-thaw cycles.
For your safety and health, please wear lab coats and disposable gloves for operation.
