PDF DatasheetRat IL 1RA Bioactive Protein Product Attributes
Product Type: Bioactive Protein
Recombinant IL 1RA based upon sequence from Rat
Host: QP10697 protein expressed in E. Coli.
Available Tags: Untagged
Protein Construction: A cDNA sequence encoding the sequence of IL 1RA was constructred and used to recombinantly synthesize the protein.
Recommended Applications: Bioactive
Application Notes
Recommended Reconstitution Instructions: 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.
Bioactivity Data: 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.

Purity: Greater than 95.0% as determined by SDS-PAGE.
Endotoxin Levels: < 1.0 EU per ug protein as determined by the LAL method.
Buffer: Lyophilized from a 0.2µm filtered concentrated solution in PBS, pH 7.4.
Storage Conditions: 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.
Physical Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.
