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 particularly close to IL13. IL4, IL13 and IL5 are found to be regulated coordinately by several long-range regulatory elements in an over 120 kilobase range on the chromosome.
BP000157-CYT-398: Recombinant Porcine IL-4 Protein
Source: 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-PAGE and RP-HPLC.
Formulation: 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 < 100 ug/ml, which can then be further diluted to other aqueous solutions.
Shipping: The product is shipped with ice pack. Upon receipt, store it immediately at the temperature recommended below.
Stability & Storage: 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.
