Description : Interleukin-4 (IL-4) is a pleiotropic cytokine that induces differentiation of naive helper T cells (Th0 cells) to Th2 cells. It is produced by mast cells, activated T cells and bone marrow stromal cells. It has many biological roles, including the stimulation of activated B-cell and T-cell proliferation, and the differentiation of CD4+ T-cells into Th2 cells. In addition, IL-4 enhances both secretion and cell surface expression of IgE and IgG1 and also regulates the expression of the low affinity Fc receptor for IgE (CD23) on both lymphocytes and monocytes. The mouse IL-4 has a compact, globular fold, stabilised by 3 disulphide bonds and contains 121 amino acids residues which is a single non-glycosylated polypeptide. The human IL-4 shares about 40% aa sequence identity with mouse/rat IL-4 and they are species-specific in their activities.
Source : E.coli

Form : Lyophilized from a 0.2μm filtered solution in PBS, pH 7.4.
Bio-activity : Fully biologically active when compared to standard. The ED50 as determined by the dose-dependant prolifiration of Murine HT-2 cells is less then 2 ng/ml, corresponding to a Specific Activity of > 5 × 10⁵ IU/mg.
Molecular Mass : Approximately 13.5 kDa, a single non-glycosylated polypeptide chain containing 121 amino acids.
Protein length : 121
AA Sequence : MHIHGCDKNHLREIIGILNEVTGEG TPCTEMDVPNVLTATKNTTESELVC RASKVLRIFYLKHGKTPCLKKNSSV LMELQRLFRAFRCLDSSISCTMNES KSTSLKDFLESLKSIMQMDYS
Endotoxin : Less than 1 EU/µg of rMuIL-4 as determined by LAL method.
Purity : >97% by SDS-PAGE and HPLC analysis.
Storage : Use a manual defrost freezer and avoid repeated freeze-thaw cycles. 12 months from date of receipt, -20 to -70 centigrade as supplied. 1 month, 2 to 8 centigrade under sterile conditions after reconstitution. 3 months, -20 to -70 centigrade under sterile conditions after reconstitution.
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 centigrade. Further dilutions should be made in appropriate buffered solutions.

    By testing immunogenicity in animal models, detect whether an immune response is induced.

    11/09/2020

      The structure of the recombinant protein was analyzed by nuclear magnetic resonance (NMR), X-ray crystallography or electron microscopy, and the results showed that the protein was stable.
