IL 1RA Protein

• Catalog Number: orb426476
• Category: Proteins
• Description: Recombinant of IL 1RA protein
• Form/Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.
• Buffer/Preservatives: Lyophilized from a 0.2µm filtered concentrated solution in PBS, pH 7.4.
• Purity: Greater than 95.0% as determined by SDS-PAGE.
• Protein Sequence: HPAGKRPCKM QAFRIWDTNQ KTFYLRNNQL IAGYLQGPNT KLEEKIDMVP IDFRNVFLGI HGGKLCLSCV KSGDDTKLQL EEVNITDLNK NKEEDKRFTF IRSETGPTTS FESLACPGWF LCTTLEADHP VSLTNTPKEP CTVTKFYFQE DQ
• Application notes: Cytokines And Growth Factors
• Source: Escherichia Coli
• 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.
• Solubility (25°C): 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.
• Storage: 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
• Alternative names: IRAP, IL1F3, IL1RA, IL-1ra3, ICIL-1RA, IL1RN, IL1
