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: 12615 Dalton. N-terminal sequence analysis: Met-His-Lys-Cys-Asp. The ED50 range = 1 to 4 ng/ml corresponding to a Specific Activity of 0.25-1 MIU/mg. The biological activity is determined by measuring the dose dependent proliferation of human TF-1 cells. A concentration range of 0.1 to 10.0 ng/ml is effective for most in vitro applications. Purity: > 95% by SDS-|Lyophilized from a concentrated (1 ug/ml) solution in water containing no additives. Reconstitution: It is recommended to reconstitute the lyophilized Interleikin-4 in sterile 18 MΩ-cm H2O not 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
