Validation Data Gallery

• 

  Purity of recombinant human IL-4 was determined by SDS- polyacrylamide gel electrophoresis. The protein was resolved in an SDS- polyacrylamide gel in reducing and non-reducing conditions and stained using Coomassie blue.

• 

  Recombinant human IL-4 (HZ-1004) stimulates dose-dependent proliferation of the TF-1 human erythroleukemic indicator cell line. Cell number was quantitatively assessed by PrestoBlue® cell viability reagent. TF-1 cells were treated with increasing concentrations of recombinant IL-4 for 72 hours. The EC50 was determined using a 4-parameter non-linear regression model. The EC50 range is 0.07-0.4 ng/mL.

Background

Interleukin-4 (IL-4), a member of the α-helical cytokine family, is produced by activated CD4+ T cells, basophils, and mast cells. It promotes the proliferation and differentiation of antigen presenting cells. IL4 also plays a pivotal role in antibody isotype switching and stimulates the production of IgE. This cytokine has been applied in the treatment of autoimmune disorder like multiple myeloma, cancer, psoriasis, and arthritis. IL4 has also been extensively applied to inhibit detrimental effect of Th1. It may promote the growth of epithelial tumors by mediating increased proliferation and survival (PMID: 24489573;3049907;21663408)
