| Introduction | |
| IL4 is a pleiotropic cytokine produced by activated T cells. IL4 is a ligand for interleukin 4 receptor. The interleukin 4 receptor also 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. Two alternatively spliced transcript variants of this gene encoding distinct isoforms have been reported. | |

| Escherichia Coli. | |
| Physical Appearance | |
| Sterile Filtered White lyophilized (freeze-dried) powder. | |
| Formulation | |
| Lyophilized from a 0.2 µm filtered concentrated solution in 1xPBS, pH 7.4. | |
| Stability | |
| Lyophilized Interleukin-4 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IL4 should be stored at 4°C between 2-7 days and for future use below -18°C. Please prevent freeze-thaw cycles. | |

| Biological Activity | |
| The ED 50 as determined by the dose-dependent stimulation of TF1 cells is less than 0.2ng/ml, corresponding to a specific activity of > 5.0×10 6 IU/mg. | |
| Solubility | |
| It is recommended to reconstitute the lyophilized Interleikin-4 in sterile 18MΩ-cm H2O not less than 100 µg/ml, which can then be further diluted to other aqueous solutions. | |
| Precautions | |
| IL 4 Rat is for research use only and not for use in diagnostic or therapeutic procedures. | |
