IL-4 Protein

Description:
|Introduction The interleukin 4 receptor binds to IL13, which may contribute to many overlapping functions of this cytokine and IL13. STAT6, a signal transducer and activator of transcription, has been shown to play a central role in mediating the immune regulatory signal of this cytokine. This gene, IL3, IL5, IL13, and CSF2 form a cytokine gene cluster on chromosome 5q, with this gene |E. coli-derived. Predicted molecular mass: 14.9 kDa. The ED50 as determined by the dose-dependent stimulation of TF1 cells is less than 0.2 ng/ml, corresponding to a specific activity of >5.0×106 IU/mg. Purity: > 97.0% as determined by RP-HPLC and by SDS-|Lyophilized from a 0.2 um filtered concentrated solution in 1xPBS, pH 7.4. Reconstitution: It is recommended to reconstitute the lyophilized Interleikin-4 in sterile 18 MΩ-cm H2O not less than 100 ug/ml, which can then be further diluted to other aqueous solutions. Shipping: The product is shipped with ice |Use a manual defrost freezer and avoid repeated freeze-thaw cycles. 12 months from date of receipt, -20 to -70°C as supplied. 1 month, 2 to 8°C under sterile conditions after reconstitution. 3 months, -20 to -70°C under sterile conditions after reconstitution. |Other IL-4 Proteins: Reco|IL-4 Polyclonal Antibody IL-4 Polyclonal Antibody IL-4 Polyclonal Antibody IL-4 Polyclonal Antibody IL-4 Monoclonal Antibody IL-4 Monoclonal Antibody
