| Purity | Greater than 95.0% as determined by SDS-PAGE. | Source | Escherichia Coli. |
| Phycical Appearance | Sterile Filtered White lyophilized (freeze-dried) powder. | Shipping Condition | Shipped at Room temp. |
| Synonyms | IRAP; IL1F3; IL1RA; IL-1ra3; ICIL-1RA; IL1RN; IL1 inhibitor; IL-1ra; MGC10430. | ||
| Amino Acid Sequence | HPAGKRPCKM QAFRIWDTNQ KTFYLRNNQL IAGYLQGPNT KLEEKIDMVP IDFRNVFLGI HGGKLCLSCV KSGDDTKLQL EEVNITDLNK NKEEDKRFTF IRSETGPTTS FESLACPGWF LCTTLEADHP VSLTNTPKEP CTVTKFYFQE DQ | ||
| Solubility | It is recommended to reconstitute the lyophilized IL 1RA in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions. | ||
| Stability | Lyophilized IL 1RA although stable at room temperature for 3 weeks, should be stored desiccated below -18°C . Upon reconstitution IL 1RA should be stored at 4°C between 2-7 days and for future use below -18°C .Please prevent freeze-thaw cycles. | ||
| Biological Activity | Fully biologically active when compared to standard. Measured by its ability to inhibit IL1a-dependent proliferation in D10.G4.1 mouse helper T cells. The ED50 for this effect is typically 30-150ng/ml (corresponding to a specific activity of 6,667-33,334units/mg ) in the presence of 50pg/ml of rrIL1a. | ||
| Formulation | Lyophilized from a 0.2µm filtered concentrated solution in PBS, pH 7.4. | ||
Interleukin-1 ra is a member of the interleukin 1 cytokine family. This protein inhibits the activities of interleukin 1, alpha (IL1A) and interleukin 1, beta (IL1B), and modulates a variety of interleukin 1 related immune and inflammatory responses. This gene and five other closely related cytokine genes form a gene cluster spanning approximately 400 kb on chromosome 2. A polymorphism of this gene is reported to be associated with increased risk of osteoporotic fractures and gastric cancer. Four alternatively spliced transcript variants encoding distinct isoforms have been reported.
