Recombinant of IL 1RA protein
Product Specifications
Product Name Alternative
IRAP, IL1F3, IL1RA, IL-1ra3, ICIL-1RA, IL1RN, IL1 inhibitor, IL-1ra, MGC10430.
Source
Escherichia Coli
Purity
Greater than 95.0% as determined by SDS-PAGE.
Bioactivity
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.
Form
Sterile Filtered White lyophilized (freeze-dried) powder.
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.
Storage Conditions
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
Notes
For research use only.
