| 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. . |
| Recombinant Human IL-4 is expressed from Expi293 with His tag and Avi tag at the C-terminal. It contains His25-Ser153. |

| The protein has a predicted MW of 17.8 kDa. Due to glycosylation, the protein migrates to 23-25 kDa based on the Tris-Bis PAGE result. |
|
| Immobilized Human IL-4 at 0.5ug/ml (100ul/well) on the plate. Dose response curve for Human IL-4 R alpha, hFc Tag with the EC50 of 18.4ng/ml determined by ELISA. See testing image for detail. |
