| Scientific Background | Interleukin-4, also known as IL4, is a secreted protein which belongs to the IL-4/IL-13 family. Interleukin-4/IL4 has many biological roles, including the stimulation of activated B-cell and T-cell proliferation. In the presence of IL-4 and IL-13, cytokines that are produced in a Th-2 type response, particularly during allergy and parasitic infections, macrophages become differentially activated, and this cytokine is a ligand for interleukin 4 receptor. |
| Molecular Mass | The protein has a predicted MW of 40.9 kDa. Due to glycosylation, the protein migrates to 50-60 kDa based on Bis-Tris PAGE result. |
| Sl Sequence | His25-Ser153 |
| Solubility | Dissolve the lyophilized protein in distilled water. It is recommended to resuspend at 0.5 mg/mL if the lyophilized powder is 100 μg or less, at 1mg/ml for 500μg or 1mg lyophilized powder. Do not mix by vortex or vigorous shaking. |
| Appearance | Lyophilized |
| Endotoxin Levels | Less than 0.1 EU per μg by the LAL method. |
| Expression System | HEK293 |
| Gene Id | P05112-1 |
| Amino Acid Sequence | Recombinant Human IL-4 Protein is expressed from HEK293 with hFc (IgG1) tag at the C-terminus.It contains His25-Ser153. |
| Storage | -20 to -80°C for 12 months as supplied from date of receipt.；-80°C for 3 months after reconstitution.；Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles. |
